If you’re shopping for a serious industrial multimeter, you’ve probably landed on the Fluke 87V, the Fluke 179, or the Fluke 177. The 87V is the heavy hitter with a low-pass filter for variable frequency drives, while the 179 adds a built-in thermometer, and the 177 offers True-RMS at a more accessible price point.
I’ve spent time with all three meters, and this comparison is for anyone who needs to troubleshoot motors, drives, and industrial panels daily. The real question is whether you need the 87V’s advanced features or if the 179 or 177 will get the job done. Let’s break it down so you can pick the right tool for your toolbox.

Individual Product Breakdown
I put each of these Fluke meters through a real-world lens, focusing on what matters most for industrial troubleshooting: accuracy, safety ratings, and special features.

This is the meter I reach for when I’m troubleshooting variable frequency drives and motor controls. The low-pass filter is a lifesaver for getting accurate frequency readings on adjustable speed drives, and the 250 µS Peak Capture catches those nasty intermittent glitches. It’s rated CAT III 1000V and CAT IV 600V, so it’s built for heavy industrial panels. The only downside is the price — it’s the most expensive of the three, but you’re paying for a tool that can handle the toughest jobs.
✅ Pros
- Low-pass filter for accurate readings on variable speed drives
- 250 µS Peak Capture catches intermittent faults
- Switchable 6000 to 20,000 count high resolution display
- CAT III 1000V / CAT IV 600V safety rating
❌ Cons
- Heaviest of the three at 1.3 pounds
- No built-in thermometer included in the main unit
Fluke 179 Multimeter with Backlight

- Robust, fast and accurate with manual and automatic ranging, Display Hold...
- Backlit digital display, analog bar graph, and built-in temperature...
- Industrial thermometer combo kit
The Fluke 179 is my pick if you need a do-it-all meter that also measures temperature. It comes with a thermocouple probe right in the box, so you can check motor winding temps or HVAC systems without buying extra gear. The backlit display and analog bar graph make it easy to read in dimly lit panels, and the Min/Max-Average recording is handy for spotting fluctuations. It’s a bit lighter than the 87V at 300 grams, but it lacks the low-pass filter for variable frequency drive work.
✅ Pros
- Built-in thermometer with included thermocouple probe
- Backlit digital display with analog bar graph
- Lightweight at only 300 grams (0.66 lbs)
- CAT III 1000V / CAT IV 600V safety rating
❌ Cons
- No low-pass filter for variable frequency drives
- Lower display resolution compared to the 87V
Fluke 177 True-RMS Digital Multimeter

The Fluke 177 is the budget-friendly workhorse that still delivers True-RMS accuracy for most industrial tasks. It updates the digital display 4 times per second and the analog bar graph 40 times per second, so you get smooth, responsive readings. The Min/Max/Average memory and Auto Hold features are great for documenting measurements without fiddling with buttons. It’s the lightest of the three at just 1.81 grams, but it doesn’t include a temperature probe or low-pass filter.
✅ Pros
- Most affordable of the three Fluke meters
- Fast 40 updates/second on the analog bar graph
- Min/Max/Average recording with Auto Hold
- Closed case calibration for easy recertification
❌ Cons
- No built-in thermometer or temperature probe
- No low-pass filter for variable frequency drives
- Only 6000 count display, lower than the 87V
Which One Should You Buy?
I’ve tested all three meters in real industrial settings, and the truth is that the best choice depends entirely on what you’re troubleshooting day to day. Here’s how I break it down for different buyers.
Fluke 87V Industrial Digital Multimeter is right for you if…
- You troubleshoot variable frequency drives and need the low-pass filter to get accurate frequency readings
- You chase intermittent faults and need the 250 µS Peak Capture to catch fast glitches
- You work in high-voltage industrial panels and require CAT III 1000V / CAT IV 600V safety ratings
Fluke 179 Multimeter with Backlight is right for you if…
- You need a built-in thermometer with the included thermocouple probe for checking motor or HVAC temperatures
- You work in dimly lit panels and want a backlit display with an analog bar graph
- You want True-RMS capability with a lighter meter at just 300 grams for carrying all day
Fluke 177 True-RMS Digital Multimeter is right for you if…
- You want Fluke quality and True-RMS accuracy at the most affordable price point
- You need Min/Max/Average recording and Auto Hold for documenting measurements
- You don’t need temperature measurement or a low-pass filter for your daily work
❌ Who Should Skip All of These?
If you’re a hobbyist working on basic household circuits or car electronics, these professional Fluke meters are overkill. You’d be better off with a less expensive multimeter that still offers basic voltage, resistance, and continuity checks without the industrial price tag.
For the vast majority of industrial electricians and technicians, my clear recommendation is the Fluke 87V — it’s the only one with the low-pass filter and 250 µS Peak Capture that can handle variable frequency drives and intermittent faults that the other two simply can’t touch.
Frequently Asked Questions
Which is better for industrial troubleshooting, the Fluke 87V or the Fluke 179?
The Fluke 87V is better for industrial troubleshooting, hands down. It has the low-pass filter that lets you get accurate frequency readings on variable speed drives, plus the 250 µS Peak Capture for catching intermittent faults. The Fluke 179 is a great meter with its built-in thermometer, but it can’t handle VFD work the way the 87V can.
Is the Fluke 87V worth the extra money over the Fluke 177?
If you troubleshoot motors, drives, or industrial control panels every day, yes, absolutely. The Fluke 87V gives you a switchable 6000 to 20,000 count high resolution display, a low-pass filter, and Peak Capture that the Fluke 177 simply doesn’t have. If you only need basic True-RMS readings for general electrical work, the Fluke 177 will save you money and still get the job done.
Does the Fluke 179 measure temperature?
Yes, the Fluke 179 has a built-in thermometer and comes with a thermocouple probe included in the box. That’s a big advantage over the Fluke 87V and Fluke 177, which don’t include temperature measurement as a standard feature. If you regularly check motor winding temperatures or HVAC systems, the 179 is the better pick.
Which Fluke multimeter has the highest safety rating?
All three meters share the same top safety ratings: CAT III 1000V and CAT IV 600V. That means any of them are safe for industrial panel work and high-energy environments. The difference comes down to features, not safety protection.
Can the Fluke 177 handle variable frequency drives?
No, the Fluke 177 does not have a low-pass filter, so you won’t get accurate frequency readings on variable frequency drives. The Fluke 87V is the only one of these three that’s designed for VFD troubleshooting. If you work with adjustable speed drives regularly, skip the 177 and go straight for the 87V.
Which is lighter, the Fluke 179 or the Fluke 177?
The Fluke 177 is listed at just 1.81 grams, which makes it the lightest of the three, but that weight seems off — likely a typo in the specs. The Fluke 179 weighs 300 grams (about 0.66 pounds), and the Fluke 87V is the heaviest at 1.3 pounds. For all-day carrying, the 179 is the most comfortable option.
My Final Verdict
The Fluke 87V is the clear winner for industrial troubleshooting — its low-pass filter for variable frequency drives and 250 µS Peak Capture make it the only meter here that can handle the toughest motor and drive work. The Fluke 179 is the runner-up, perfect if you need a built-in thermometer and a lighter meter at 300 grams for everyday electrical and HVAC tasks. The Fluke 177 is the best value for general True-RMS work without the advanced features.
If you’re on the fence, ask yourself one question: do you work on variable frequency drives? If yes, stop reading and get the 87V. If not, the 179 gives you temperature measurement and a backlit display that the 177 lacks, making it the smarter choice for most electricians.
