When you think of great tools and devices to have around the house, typically the first thing that comes to mind are power drills, sanders, and others, but the Multimeter doesn’t get as much attention. A multimeter has become for me one of the top required home DIY items that you must have.
So, what is it? A multimeter at first glance will look like it’s written in a foreign language with all sorts of symbols and buttons on it but don’t let that intimidate you. A multimeter is an electronic device that is used by electricians and DIY homeowners to test items for voltage, temperature, amps, and resistance in different items like outlets, batteries, metal objects, and electrical wires.
Why would you need one of these? If you’re living in a small apartment or don’t own a car then you probably will not find many uses for one of these. If you’re a homeowner and you have your own car (which the majority of us do) then you should definitely have one of these.
How we pick multimeters?
There are many different multimeters on the market with different functionality, measurement types, and price. So how do we pick them out? Below are the main factors we look at when determining the best multimeter:
- Price and Value for your money
- Measurement types:
- True RMS and Autoranging capabilities
- LCD or LED display types and backlight
- Needs and uses
- Safety ratings
- Known/trusted brand types
If you’re just starting out, some of these terms may be foreign to you, but we will discuss more of these in detail when we review each of the multimeters below which will help you decide which is best for you.
Overview of the TOP 10 Best Multimeters
When we were selecting the best multimeters for 2018, we had a fun time trying them out and determining which functionalities are the most important. The hard time about comparing each multimeter against the other is that each multimeter can often be specific to a type of multimeter. No multimeter can do every measurement as the devices simply have limitations on how many different measurements you can get on one small hand-held device.
When we selected some of the top functionalities to compare these were the ones which we found consistently across many of the multimeters that we felt were important to the every-day user.
These are the top 10 best multimeters of 2018 and some of the key highlights of each (Check multimeter comparison table below).

What Are The 4 Different Types of Digital Multimeters?
There are many different types of meters that can measure different objects, devices, wires, and circuits. If it’s dealing with electrical measurements, typically you’ll need a multimeter to accomplish this. The best multimeters are designed to be able to measure the voltage and amps of a specific object without harming the user.
If you’re looking to be able to take electrical measurements or to measure continuity, you’ll need a multimeter but which one will you get? Here in this guide, we’ll review the 4 most common types of multimeters on the market that you may see and why you would use them.
Fluke Digital Multimeter
When you start your search for the best multimeter and start understanding the different types and brands, the first thing you’ll see a lot of us the Fluke Brand. They are extremely well known in the multimeter industry and are top of the line when it comes to quality and precision. If you want a multimeter you can trust to get the job done right every time, go for Fluke. They typically come with an increased price tag, but they will be worth it in the long run.
The first and most important multimeter to understand is the digital multimeter. This is the most common type of multimeter that you’ll see around most homes and garages. A digital multimeter is most commonly used to measure voltage and resistance in your home, office, or vehicle.
This is done by using two probes black/red one which is the lead and one being the grounding probe. Each measurement setup and a process is very different but typically follows the same process. Make sure to review and understand each process for measurement prior to completing it so you don’t damage the multimeter or get injured.
Below is a full list of the potential capabilities of a digital multimeter although this can change from each device to device:
- DC/AC Amps
- Diode Testing
- Voltage Detection
- Non-Contact Detection
No matter what level of expertise you are with using a multimeter, the digital multimeter is easy to use and learning the basics can be quick by review a few YouTube videos. If you’re not sure which brand to go with when selecting a digital multimeter, go with Fluke. Some of my favorite are the Fluke 116 and Fluke 117 devices.
While most multimeters are similar, there is a key difference between a digital multimeter and a clamp multimeter (Or just clamp meter). A clamp multimeter is used to measure current in a wire while the digital multimeter primarily measures voltage.
The great thing about the recent developments in technology, both of these multimeters has so many overlapping measurement capabilities that it can be hard to determine which one you should get. The key difference between the two really is the clamp which is either a part of the multimeter or a separate attachment. The functionality of the clamp is to measure the current flowing through a specific wire.
To use a clamp meter, it’s much different than a standard multimeter which has 2 probes. Instead, you’ll open the hinges of the circular clamp and put the wire inside it and close the clamp around the wires. The multimeter will then measure the flow that is pulsing through the clamp to determine the amps running through it.
While a clamp meter is primarily known for measuring flow through wires, it still also comes with probes used in a standard digital multimeter and can still measure most of the same things. Using the probes allows for some of the following measurements:
- AC and DC Amps
If you’re looking for great clamp meters, Fluke also has some really great models including the Fluke 323. You can also go with a more affordable meter like the Amprobe 210 which has most of the same measurements but is not branded with the Fluke name but still performs similarly.
Autoranging Multimeter and True RMS
While in the past most multimeters whether it be a digital or clamp multimeter relied on the user understanding each measurement and how to adjust the range of it to appropriately understand it. But a new functionality built into many multimeters is the auto-ranging functionality.
These types of multimeters are great because they typically allow you to either use manual mode or auto-ranging mode. When in the auto-ranging mode you typically don’t have to adjust the measurements or change the dial when you’re completing your measurements. It will adjust as necessary to output the results for you.
On top of just auto-ranging, it’s important to understand some other features which can be found on different multimeters these days. The True RMS technology which almost all Fluke devices have is one of the best as it ensures that no matter what measurement you’re making if there is external electrical interference, it will still provide proper measurements to you. This is important especially if you plan to use the multimeter for professional use.
Some important functionality you should look for when purchasing one is the auto shut-off functionality which saves you on battery life. You will also find the hold and min/max functionality useful for saving measurements and finding out the highest and lowest range when you completed the measurement.
Now let’s go back in time and understand the oldest form of multimeters and that’s the analog multimeter. While analog multimeters are still sold in stores today, we do not suggest purchasing analog multimeters as they are more difficult to get accurate measurements and tend to get uncalibrated easily.
An analog multimeter doesn’t have a digital screen but rather a measurement range with a bar that moves to show the range of the current. You can think of this similar to a weighing scale at home. In the past, most of them when you stepped on had a circular disk that moved to show how much you weigh, but now they all have a digital screen which is more effective and accurate.
While it’s important that you know these exist when you’re making a purchase, we still suggest to go with a multimeter with a digital screen that has the more advanced technology.
If you’re still stuck with what multimeter to get, read further on each of our guides for the best digital multimeters and clamp multimeters to help you decide more.
What to Consider Before Buying a Multimeter?
If you’re ready to buy your multimeter, there are a few key things to think about before you take that next step. The first thing to consider is the cost. There is a large range ($20 to $500) in terms of cost for multimeters. Sometimes the cost can be warranted as the device has many great features and capabilities, however, many times the cost does not justify the device.
If you’re a DIY home owner or car owner, there should be no need to spend more than $50 on a multimeter. If you are a professional, you’ll definitely want to consider the brand and price as a good sign to the accuracy and functionality of the device.
The next thing to consider is what features you need in a multimeter. Do you need it for testing switches, power sources, batteries, motors, components, wires, etc? You also want to know if the different built-in capabilities like auto-ranging, data hold, backlight, min/max, and other functions are important. While to many these are important, some others may not need them.
If you want to measure temperatures for heating and cooling, then make sure the device comes with a thermometer probe. This helps when working with objects which may get too warm due to electricity flow.
If you’re working with computers, you may want to make sure the multimeter can measure in ohms and that you are able to select a larger range of voltages.
If you get stuck, a very trustworthy way to see which device is best for you is to determine what you’ll use it for and then find the closest devices that match it and read as many of the reviews online about it before you buy it.
Difference between digital multimeter and analog multimeter
While there are two different types of multimeters, analog and digital, it is quite rare to see analog multimeters any longer.
An analog multimeter is one that has a needle that will show the current flow of energy running through the multimeter by traveling through a coil meter. Inside the multimeter based on the measurement selected it will have certain resistors which allow the device to determine the AC or DC current/voltage.
With a digital multimeter, different circuits are used to test the sample of current being sent to the device. It is then displayed on the screen of the device quickly for the user to see.
In general, analog multimeters are more inaccurate and difficult to use and read. If you are looking to purchase a multimeter, we do not suggest to get an analog multimeter any longer. Even the cheapest multimeters on the market these days are more accurate that the more expensive analog ones.
How to use a multimeter
If you’ve just got your multimeter and you’re ready to use it, there are a few quick tips on getting it setup and ready to use. The first thing is to ensure you have working batteries in the device. Depending on your device, you will need to open the battery compartment and enter either 9V, AA, or AAA batteries into the device.
Once the batteries are in, the next step is to input the leads into the device. It will come in both black and red leads. Simply plug the black lead into the one that says COM and the red one into the one for Volts (labeled with V). You may need to change the red one for different measurements but the black one always remains constant.
Plugging these in won’t hurt you to start but it’s best to only ever touch the colored rubber part of the leads and never touch the metal parts if you want to avoid getting shocked (which can be dangerous).
The next step in using the multimeter will be to determine what you’re looking to test. This is where the user manual and using different YouTube tutorials will come in great.
Best Multimeter for Electronics Technicians
While there are many great multimeters on the market, there are two that come top of mind for electronics technicians, and it’s no surprise that they are both the Fluke brand.
- The Fluke 179 is one of the best for everyday use in industrial troubleshooting. It can read up to 1,000 Volts and can measure resistance, frequency, temperature, and both AC/DC current and voltage. It also has true RMS reading capability.
- The Fluke 115 is as well one of the best in the market for both electronics and field service applications. It can read up to 600 volts and can measure both AC/DC current and voltage as well as measuring resistance and frequency.
All Fluke branded devices are made to withstand heavy use and although they are on the more expensive side, they are definitely built to last and provide you with the most accurate readings.
Best Multimeter for Electronics Hobbyist
For those DIY type who want to be able to measure basic electrical devices and objects, there is no reason to spend outrageous amounts of money on the expensive Fluke brands. In this case, I have one recommendation for an all-around the best multimeter for hobbyists.
- The Innova 3320 is by far my favorite for an affordable multimeter to use around the house. It has a built-in auto-ranging capability making it easy to use. It also has an easy to see display with large print as well as a nice rubber casing making it perfect for those of us who are clumsy and knock it around or drop it.
Multimeter Basics – Everything You Need to Know
While you may not know what the different symbols and letters mean right away you should be somewhat familiar with the important terms:
- DC/AC: Direct Current and Alternating current. You can change this by simply pushing a button or selector on your multimeter. The difference in these two currents is simple in that with DC the flow of electricity is only going one way where as in AC the current can flow in one direction and then change to the other direction.
Most electrical outlets are AC which is easy as they usually have a large grid to work on and can transfer power back and forth to eliminate waste. Most electronic devices and household appliances work on DC as they only require the power source to go one way to the device.
- Continuity: This allows you to test if there are breaks in an electrical circuit like a faulty/cut wire etc. It sends electricity into one end and checks if it has a response on the other end.
- Voltage: This measures how strong electricity is being pushed through a specific circuit. The higher the voltage the stronger the force. This is measured in Volts (V).
- Current: This measures the amount of electricity going through a circuit and is measured in amperes (A).
- Resistance: This measures the difficulty of a current of electricity to flow through an object. The higher the resistance means it’s more difficult for energy to flow through it. This is measured in ohms (Ω).
There are many other values including frequency, capacitance, transistor, temperature, etc, but those are useful to specific situations and may not be needed if you are an average at-home user. If you want something that can test everything, then for a little bit more money you can invest in a good quality one that has more options.
Features of the best Multimeters
When we look at selecting the best multimeter we always take into consideration the capabilities, price, durability, and features.
One of the most important features of a multimeter is the auto-ranging functionality. If your device doesn’t have auto-ranging then it should only be sold to advance users who understand all aspects of electricity and know how every measurement works. Auto-ranging is perfect for almost all uses so this is a very important capability.
Other great functionalities are the hold and min/max functionalities. The hold is perfect for keeping data present when you may not be able to write it down. The min/max keeps both the lowest and highest measurement you took during a specific reading.
I personally feel that the auto-shutoff capability is very important as well when selecting a multimeter as it has saved my battery (and cost) hundreds of times.
The display is as well a huge consideration when we select the best multimeter as some multimeters are difficult to read and require you to be in the perfect lighting situation. That is why a large, clear, easy to read screen is very important as well as it having a backlight to ensure you can see the readings even in a low-light situation.
From here, each multimeter starts to become drastically different from cost to measurement features including capacitance, resistance, voltage, temperature and much more.
Cost may not be important to some people but to others, it’s very important. There are a few things to know when seeing the cost of a multimeter.
If you are a hobbyist and just want a simple multimeter to test basic DIY home tasks, select one of the great multimeters that don’t have a high cost. You can typically get one for around $20-30 USD and it will be able to do many of the tasks you need with accuracy and last quite a long time as well.
If you are a professional, there are still some decent options that won’t break the bank for around $100-150 USD.
If cost isn’t an option, then my best recommendation for you is to go with only the Fluke branded multimeters. These will always be higher in cost but you are guaranteed to have a great device with accurate readings and output.
Digital multimeters present measurements in a direct format that does not require any manual calculating of the exact value. They are also free from the errors of analog meters as they have no moving parts and don’t wear down due to shock and movement issues.
This does not mean that a multimeter can become inaccurate over time. To ensure your multimeter is accurate, it is suggested to have it calibrated at least once a year. Calibration of a multimeter can be done manually by reading the user guide, however, if your multimeter is used for professional use it is suggested to contact an expert to have your multimeter calibrated.
Here you can see an example of how to calibrate multimeter:
Using a multimeter is quite simple to do, however, there are some things you need to pay close attention to in order to protect yourself and the multimeter alike.
The first safety precaution is to always watch for signs of damage to the device. If you see cracks, leaks, or any other damage to the device this could put you at risk of shock as the built-in shock protection may no longer be working properly.
Along with the device itself from being damaged, one of the more important parts of the multimeter is the probes used to test objects. If they become damaged in any way (cracking, breaking, etc) they should be removed and replaced before using the multimeter again. Additionally, if they no longer fit into the ports, they should be replaced.
Another safety reminder is that you should always assume any object you are testing which “might” be connected to an electrical source is probably live. Meaning it has electricity flowing through it and you should never touch it before testing it with your multimeter. This will help you to avoid getting shocked which can often be life threatening.
As a last safety reminder, water and electricity never mix well so if ever you are working in a situation that liquids are present, make sure to always wear your safety gear including gloves, head ware, and other protective gear to keep you safe.
Multimeter Extra Probes and Accessories
My personal favorite accessory for my multimeter is a carrying case. While many multimeters don’t come with a carrying case, I find it to be very helpful to keep all of the cords collected and to keep it from getting too much dust and dirt on it keeping it clean and lasting long.
There are also many different types of probes which can be used with your multimeter for testing surfaces and temperatures. While it is not required to have extra probes, it may be useful to have this if you are working in a professional environment in case one breaks you won’t have to wait to continue the job until you buy new probes. Some probes are also much longer than others which can be very useful if you are trying to reach hard to get areas under a car or inside a large engine.
Clamps are also very useful to attach your multimeter to a specific object while you move the probes to a different area.
When you’re looking at basic multimeters they typically measure AD/DC Voltage, current, resistance, continuity, and diodes. When you start looking at advance multimeter features these typically include measurements like capacitance, frequency, temperature, and pressure.
When you start shopping for the best multimeter you want to consider what functions and measurements you want not only present but also possibly in the future.
For some advanced features which may only show up in more high-end multimeters include graphical display on-screen for identifying irregularity. You may also see a data-log to monitor and store data over a longer period of time.

Overall, there are many amazing multimeters on the market currently and finding the best one can often be difficult. It’s important to always remember to consider the cost and the measurement features as the primary importance when starting your selection process. Once you know what you need it for and your cost range, you can start to limit the number of multimeters to choose from.
As a general rule, if you want one of the best multimeter brands, go for the Fluke branded ones. If you’re a new multimeter user, make sure it always has auto-ranging capabilities. And not all multimeters measure temperature, so if that is a requirement make sure it includes a thermometer.
Keep learning more about the use of a multimeter as they can often be a huge cost saving device eliminating the need for you to pay extra money for professionals to do simple tests on your home and car. Saving you time, and money.
