Fluke 116 vs 117: The Ultimate Multimeter Battle

When faced with picking out a multimeter in the stores, it can become a bit overwhelming to know which one to choose from. While there are many brands, models, and statistics on each, today I’d like to review two of the top models in the market today. The Fluke 116 and 117 models are both very competitive and respectable models which we will discuss today.

Product feature breakdown

Lets break down each of these products and discuss what each of their best features are and what it can do for you.

Fluke 116 Review

Fluke 116 HVAC Multimeter, Standard


  • Great Display: The 116 has an auto-LED backlight and is optimum in all environment whether low light or bright light. This is optimum when working in darker spaces or at angels as the 116 doesn’t lose much contrast. The text is also in a large font which is great for when it is a considerable length away from you.
  • Built in Thermometer: One of the best qualities of the 116 is the ability to test temperatures of objects and liquids which makes it a perfect companion for HVAC who use this for heating and air conditioning tests. It comes with a probe which is useful for touching specific objects/liquids. As a warning, ensure none of the liquids are corrosive so you don’t jeopardize the probe.
  • Data Capture: For those of you who have a hard time remembering the values or don’t have anything to write it down on at that time, the 166 has a data capturing function. This will store the reading automatically for you until you clear it with a new one.
  • True RMS: The true RMS feature is a key desire for HVAC workers who need a precise and accurate reading. For all true RMS devices, it ensures your readings will be accurate even under unfavorable conditions. Many multimeters on the market lack this currently, but most HVAC multimeters this will come standard.
  • Best in Design: Most all Fluke devices are well designed, but the 116 is made for optimum one-hand usage which is great when your other hand is holding a probe or object. Also for are magnetic holders for the multimeter which is a great accessory for hands-free use.


  • Durable and affordable
  • Precise and Accurate
  • Easy to use


  • Display tends to lose contrast under certain angles
  • Temperature readings can be inaccurate sometimes


  • Loss of Contrast: At certain angels the device will lose contrast and while it can be a little annoying, it is not often that you will have this and a quick tilt towards you can fix it right away. We did find this to be a bit frustrating though.
  • Thermocouple Inaccuracies: Many reports have come in about temperature readings being inaccurate and while we never encountered this ourselves, it is worthwhile to mention that it may have some difficulties.
  • Country of Origin: While this isn’t the most important part, it is worthwhile to note that although they say it’s a product of the US, they are actually assembled in China.

Fluke 117 Review

Fluke 117 Digital Multimeter, Non-Contact AC Voltage Detection, Measures Resistance/Continuity/Frequency/Capacitance/Min Max Average, Automatic AC/DC Voltage Selection, Low Impedance Mode


  • Auto Shut-Off: If you are like many of us who use our multimeter often, you can easily forget to turn it off. The 117 comes with an auto shut off ability after 15 minutes of inactivity which ensures you will never pick up a dead device. This isn’t just great to save you on battery life, but it also is a great cost-saving mechanism. It’s important to note that while the device continues to detect activity, it will not shut down which is great for long-term projects that don’t require you to change settings.
  • True RMS: The 177 also has true RMS which is a highly needed ability for accurate and precise readings. It can read most all situation, no matter the conditions, within a 0.5% accuracy. While this is quite standard, it is still worthwhile to mention.
  • Non-Contact Voltage Detection: This is probably one of the most useful functionalities of the Flue 117 because it helps to keep the user safe. When you are unsure if there is voltage on an object and want to check, simply hover the multimeter over the object and wait for it to beep. If it does, it means the object has voltage present on it.
  • Display: The display of the 117 is big and bright and while it doesn’t automatically detect low-light, it has a button to turn it on quickly. The display is very easy to read, however, often can be distorted at certain angles.


  • Accurate and Precise
  • Easy to Use
  • Versatile and Reliable


  • Display can lose contrast under certain angles
  • Assembled in China


  • Loss of Contrast: Similarly to the 116 model, the Fluke 117 has many of the same issues when it comes to screen angles and contrast. It’s important to note that it is easy to adapt to this and figure out which angles show the data best.
  • Country of Origin: Again, this isn’t a deal-breaker, however, Amazon claims it is a product of the USA while it is actually assembled in China. This shouldn’t deter you from purchasing Fluke products, but many people care what country of origin their products come from.

Wrap Up

The Fluke 116 and 117 are both equally great products and have great advantages over most of the multimeters on the market today. When deciding which of these two you need, there are 2 key differences: Temperature and Non-Contact Voltage Detection.

The 116 is perfect for HVAC as it can read temperatures of objects/liquids which the 117 cannot. On the flip side, the 117 can detect voltage with no-contact which is great for electricians.

Frequently Asked Questions

The Fluke 116 and 117 have many similarities and differences which it’s important to know prior to buying either one. Here are a few different must-know facts about these two devices that you should know.

Does the Fluke 116 read temperature in C or F?

One of the big advantages of the Fluke 116 over the 117 is the fact that you can use it for HVAC uses as it can measure temperatures using the thermocouple. The Fluke 116 can read temperatures in both Celsius and Fahrenheit so it works well no matter what your measurement preference is.
