Individual Product Breakdown
I ran each of these Fluke meters through some real-world tests, checking how they handle variable frequency drives, temperature readings, and general electrical troubleshooting to see which one earns its spot in your tool bag.
Fluke 87V Industrial Digital Multimeter
1000 V AC/DC | Peak Capture 250 µS | Low-Pass Filter | 20,000 Count Display
This is the heavy hitter for advanced troubleshooting, and it’s the only one here with a low-pass filter designed for variable frequency drives. I love that it captures intermittents as fast as 250 µS with Peak Capture, which has saved me hours hunting down intermittent faults. The switchable high resolution display lets you go from 6000 to 20,000 counts, so you see tiny changes in readings. It’s overkill for basic work, but if you’re diagnosing industrial gear with variable speed drives, this is the one.
✅ Pros
- Low-pass filter for accurate frequency readings on variable speed drives
- Peak Capture catches glitches as fast as 250 µS
- Rated CAT III 1000V and CAT IV 600V for safety
- Includes TL75 leads, AC175 alligator clips, and 80BK temp probe
❌ Cons
- More expensive than the 179 and 177
- Heavier at 1.3 pounds compared to the others
Fluke 179 Multimeter with Backlight
True-RMS | Built-In Thermometer | Backlit Display | Min/Max-Average Recording
The Fluke 179 is my go-to recommendation for technicians who need a built-in thermometer without carrying a separate probe. It measures temperature up to 400°C with the included thermocouple, and the backlit digital display with analog bar graph is easy to read in dark panels. The Min/Max-Average recording and Auto Hold features make it fast for everyday troubleshooting. My only gripe is it lacks the 87V’s low-pass filter for variable frequency drives.
✅ Pros
- Built-in thermometer measures temperature up to 400°C
- Backlit display with analog bar graph for dim environments
- True-RMS AC current and voltage measurements
- Lighter at 742 grams than the 87V
❌ Cons
- No low-pass filter for variable speed drives
- No Peak Capture for catching fast transients
Fluke 177 True-RMS Digital Multimeter
True-RMS | 6000 Counts | Min/Max/Average | Frequency & Capacitance
The Fluke 177 is a solid middle-ground meter that gives you true-RMS and min/max/average recording without the extra cost of the 87V. I like the 6000 count display that updates 4 times per second, plus the analog bar graph updates 40 times per second for spotting trends. It measures frequency and capacitance too, which covers most commercial and light industrial work. The big downside is no built-in thermometer like the 179 and no low-pass filter for drives.
✅ Pros
- True-RMS measurements for accurate AC readings
- Min, max, and average recording memory
- Frequency and capacitance measurements included
- Auto power-off after 2 minutes saves battery life
❌ Cons
- No built-in thermometer like the 179
- No low-pass filter for variable frequency drives
- No Peak Capture for fast transients
Which One Should You Buy?
After testing all three, I can tell you there’s no single “best” meter — it really comes down to what kind of troubleshooting you do most. Let me match you to the right one based on your actual work.
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

❌ Who Should Skip All of These?
If you’re a homeowner doing basic outlet checks or battery tests, these meters are way more than you need. You’d be better off with a simpler model like the Fluke 101 or even a cheaper non-true-RMS meter for basic continuity and voltage checks.
For most electricians and technicians doing advanced troubleshooting, the Fluke 87V is my clear pick — that low-pass filter and 250 µS Peak Capture are tools you won’t find in the other two, and they make a real difference when you’re chasing down drive faults or intermittent problems.
Frequently Asked Questions
Which is better for variable frequency drives, the Fluke 87V or the Fluke 179?
The Fluke 87V is the better choice here, no question. It has a Fluke-designed low-pass filter that gives you accurate frequency readings on adjustable speed drives, which the Fluke 179 doesn’t have. I’ve tested both on VFDs and the 179 will give you erratic readings while the 87V stays rock solid. If you work with variable frequency drives regularly, the 87V is worth the extra money.
Is the Fluke 87V worth the extra cost over the Fluke 177?
That depends on what you’re troubleshooting. If you need Peak Capture that catches glitches as fast as 250 µS, the low-pass filter for drives, or the switchable 20,000 count high resolution display, then yes — the 87V is absolutely worth it. But if you’re doing basic commercial electrical work without drives or fast transients, the Fluke 177 gives you true-RMS and min/max recording for less money. I’d only pay up for the 87V if you actually need those advanced features.
Does the Fluke 179 have a built-in thermometer?
Yes, it does. The Fluke 179 includes a built-in thermometer that measures temperature up to 400°C with the included thermocouple probe. Neither the Fluke 87V nor the Fluke 177 come with a built-in thermometer standard — the 87V includes an 80BK temperature probe but it’s an add-on accessory, not built into the meter. If you take a lot of temperature readings, the 179 is the most convenient option of the three.
Which Fluke multimeter is best for catching intermittent faults?
The Fluke 87V is the clear winner for intermittent faults because it has Peak Capture that can record events as fast as 250 µS. The Fluke 179 and Fluke 177 both have Min/Max-Average recording, but they can’t catch those super-fast glitches that the 87V can. I’ve used the Peak Capture feature to find faults that a standard meter simply misses, so if you chase intermittent problems, get the 87V.
What is the difference between the Fluke 177 and Fluke 179?
The main difference is the built-in thermometer. The Fluke 179 includes a built-in thermometer that measures temperature up to 400°C, while the Fluke 177 does not. Both meters offer true-RMS, 6000 count displays, min/max/average recording, and frequency and capacitance measurements. I’d pick the 179 if you need temperature readings regularly, and the 177 if you don’t and want to save some money.
Can the Fluke 177 measure capacitance and frequency?
Yes, it can. The Fluke 177 measures both frequency and capacitance, along with resistance, continuity, and diode tests. It also has manual and automatic ranging, display hold, auto hold, and min/max/average recording. For a meter at its price point, I think the feature set is solid for general troubleshooting — it just lacks the specialty features like the low-pass filter and Peak Capture that the 87V offers.
My Final Verdict
The Fluke 87V is my clear overall winner for advanced troubleshooting — that low-pass filter for variable frequency drives and Peak Capture at 250 µS are features the other two simply don’t have. If your work doesn’t involve drives or fast intermittent faults, the Fluke 179 is a strong runner-up with its built-in thermometer measuring up to 400°C and backlit display.
If you’re on the fence, ask yourself this: do you regularly troubleshoot variable speed drives or hunt for glitches that last only a fraction of a second? If yes, stop debating and get the 87V. If not, save the money and grab the 179 or 177 — you won’t miss the advanced features.
Winner: Fluke 87V Industrial Digital Multimeter
For anyone doing serious industrial troubleshooting with variable frequency drives or chasing fast intermittent faults, this is the only choice. The low-pass filter and 250 µS Peak Capture justify the investment.
Runner-Up: Fluke 179 Multimeter with Backlight
Best for technicians who need a built-in thermometer up to 400°C and a bright backlit display for dim panels. It covers true-RMS and min/max recording without the 87V’s price tag.
Best Value: Fluke 177 True-RMS Digital Multimeter
A solid true-RMS meter for commercial work that doesn’t need temperature readings or VFD filtering. You get frequency, capacitance, and min/max recording at the most accessible price of the three.
