Fluke 179 vs 87V (2026): Which True-RMS Multimeter Should You Buy?

Why you should trust this comparison

I have spent years using Fluke meters across home electrical, HVAC, and light industrial jobs, and these two models sit at a decision point a lot of buyers reach. The 179 is the top of Fluke’s general-purpose 170 series, and the 87V is the long-running flagship of the industrial 80 series. People cross-shop them constantly because the prices overlap enough to make you wonder whether the 87V is worth the jump.

This comparison is built on Fluke’s published specifications and the documented feature set of each meter, not on invented bench numbers. Where I point to a difference, it comes from the official spec sheet or the feature each meter is actually sold on. The goal is to tell you which one fits your work, not to crown the one with the biggest number on the box.

How we compared them

I judged these two on the things that decide whether a meter earns a permanent spot in your bag: measurement resolution and accuracy, true-RMS behavior on noisy signals, the extras that matter day to day (temperature, frequency, capacitance), safety rating, and the specialized features that justify a higher price. I also weighed what comes in the box, since the 179 ships as a thermometer combo kit.

Both meters are true-RMS, both carry the same CAT III 1000V and CAT IV 600V safety rating, and both are built to Fluke’s usual drop-tough standard, so the comparison really comes down to resolution, accuracy, and whether you need the 87V’s motor-drive features.

How they compare at a glance

Fluke 179

The Fluke 179 is the meter I recommend to most people who want a Fluke without paying for the flagship. It is a true-RMS digital multimeter with a 6,000-count display, a backlit screen, and an analog bar graph, and it reads voltage, current, resistance, continuity, frequency, and capacitance. Its basic DC accuracy is rated at 0.09%, which is more than enough for almost any electrical or HVAC task.

What sets the 179 apart in its own lineup is the built-in thermometer. It ships as a combo kit with an 80BK temperature probe, so you can read temperature directly without buying a separate instrument, which is genuinely useful for HVAC and appliance work. Add the rugged Fluke build, the same top-tier safety rating as the 87V, and a lower price, and it becomes the easy default for general field work.

The honest trade-off is resolution and specialization. The 179 tops out at 6,000 counts and does not include the 87V’s low-pass filter for variable-frequency drives, so if your work centers on motor-drive output it is the wrong tool. For everyone else, those are features you will likely never miss.

Fluke 87V

The Fluke 87V is the industrial flagship, and it earns that title with resolution and specialized measurement features rather than a flashier display. Its headline trick is a switchable high-resolution mode that takes the display from 6,000 up to 20,000 counts, and its basic DC accuracy is rated tighter at 0.05%. For lab-grade or precision troubleshooting where the last digit matters, that resolution is the reason to buy it.

The feature that truly separates the 87V is its low-pass filter for accurate frequency and voltage measurements on adjustable speed motor drives, plus a fast 250 microsecond peak capture for catching intermittent faults. If you maintain VFDs, motors, or industrial control systems, those two features alone can justify the price gap, because the 179 simply cannot give you a clean reading on that kind of noisy drive output.

The trade-off is cost and overkill. The 87V is meaningfully more expensive, and if you never touch a motor drive and do not need 20,000-count resolution, you are paying for capability that will sit unused. It is a specialist’s meter that happens to also be an excellent generalist, not the budget-conscious pick.

Which should you buy?

Buy the Fluke 179 if you do general electrical, residential, commercial, or HVAC work and want a tough, accurate true-RMS meter with a temperature probe in the box for the lowest sensible price. It covers the vast majority of real-world tasks and leaves money in your pocket.

Buy the Fluke 87V if you regularly work on variable-speed motor drives, need its low-pass filter for clean readings, or want the extra 20,000-count resolution and tighter accuracy for precision troubleshooting. For an industrial electrician or a controls technician, it is worth the premium; for a home pro, it usually is not.

Frequently asked questions

Is the Fluke 87V worth the extra money over the 179? Only if you need what it adds: the VFD low-pass filter, 20,000-count resolution, and faster peak capture. If your work never involves motor drives or precision resolution, the 179 gives you the same safety rating and true-RMS accuracy for less.

Do both meters measure temperature? Yes. Both have a built-in thermometer function, but the 179 is commonly sold as a combo kit that includes the 80BK temperature probe, so you may not need to buy a probe separately.

Are they equally safe to use on high-energy circuits? Yes. Both carry the same CAT III 1000V and CAT IV 600V rating, so either is appropriate for the same range of electrical environments.

The verdict

These are both excellent Fluke meters, and the right choice is about your work, not about which is better on paper. The Fluke 179 is the value champion and the meter most buyers should choose, pairing true-RMS accuracy and a bundled temperature probe with a friendlier price. The Fluke 87V is the specialist, and if you troubleshoot motor drives or need its higher resolution and accuracy, its extra features earn the premium. Match the meter to the job and either one will serve you for years.
