Fluke 116 vs 117: Which One’s Best?

Image Product Details
Best for HVAC Technicians
Fluke 116 Fluke 116
  • Rugged
  • Accurate
  • Measures microamps
  • Best for Electricians
    Second place
    Fluke 117 Fluke 117
  • Fast
  • Built tough
  • No contact voltage alert
  • Asking which is better, the Fluke 116 or the Fluke 117, is like asking what’s a better shovel—a shovel for digging dirt or a snow shovel. They’re both superior about their intended uses. In the case of these Flukes, the 116 is designed for HVAC work while the 117 is geared toward electricians. They’re also both from Fluke’s 110 line of digital multimeters, which means that aside from their specialty designs, they’re essentially identical.

    But we’re going to go with the Fluke 116 because, even though we weren’t entirely sold on its built-in thermometer, at least it can measure amperage down to the micro-level. That’s a feature that many similar models come with. And while there aren’t a ton of things that require it that low, there are enough that if you’re looking for overall, everyday use that the 116 is probably the more versatile of the two.

    What’s the difference between them?


    The 117 comes with contact-free voltage sensing. You can tell if a line has a current without touching the leads, which is handy, fast, and makes the job safer. That’s for electricians. The 116 has a built-in thermometer and can read amperage down to the micro range. That’s for HVAC work. But this is also why we gave the 116 the nod. If you’re doing straight-up electric work, the electrician’s feature makes it a lot more attractive. If you’re doing all-around work, you’re more likely to make use of the 116’s microamp measurement feature.

    Both cost the same. That makes a lot of sense since they’re basically the same frame with slightly different guts packed in. These are specialty models of a basic multimeter, and neither specialty is particularly more expensive than the other. Depending on the day and what deal you can find, either model might be more affordable than the other.

    Fluke’s reputation for rock-solid building is well earned. These multimeters can take a beating and are as reliable as old Toyotas. They stay accurate for years and years. And, again, the 116 and the 117 are built from the same frame. So, neither model can claim any kind of advantage.


    Both come with Fluke’s low impedance input to reduce ghost signaling. We weren’t really crazy about the 116’s built-in thermometer because we felt like the margin of error was pretty big at the outside part of its range, but it did okay in field testing. We also liked playing with the 117’s voltage alert feature. But we liked the 116’s ability to measure microamps, which is a handy departure from other Flukes that don’t do this.

    • Doesn’t measure microamps

    What Users Say

    We get it. You think you probably would like us as people, but at the end of the day you don’t know us and we don’t know you. So you’re wondering if you can really take what we say all that seriously. You’d like to get a wider range of opinions available on the Internet, but there are so many kooks with keyboards that you wonder how much time you’ll have to spend to find reliable feedback. We also check out online reviews when we look at tools to make sure that we haven’t had an outlier experience. We’ve summarized our experiences below.

    People generally like both multimeters. Of course they do. These are both Flukes. They’re designed and built to give accurate readings for long, long years. Fluke has gotten this part of being a test tool company down.

    Overall, both models were also very much liked by the professionals they were designed for. More than one electrician called the 117 an electrician’s best friend. Others called the 116 essential for HVAC technicians. These are heady endorsements.

    Probably because these multimeters were built on the same frame, they share a common complaint: the LED display isn’t always so easy to read. This is a complaint that’s common to the 110 line, so it’s probably not model specific.

    But that’s really about it. Both models are popular with their customers for reasons that are familiar with Fluke multimeters in general. They’re built to take punishment and to deliver accurate readings quickly.


    We liked both models of Fluke multimeters as great investments within their respective professional groups—for HVAC technicians it was the 116 and for electricians, it was the 117. Both models came with features built for those professions. And it was one of those features—the 116’s microamp measuring capability—that ultimately prompted us to give that our nod. The 117’s contact-free voltage alert might be handy, but it’s not necessary. If you have something with micro amperage, then you absolutely have to have a multimeter that can test it. But, that little hitch aside, both are great multimeters that offer a generous return on your investment.
