If you’re shopping for a meter that can survive a drop down a flight of stairs or a splash of water, you’re likely stuck between the Fluke 87V and the Fluke 28 II. The 87V is the lab-grade troubleshooting legend with a 10-year warranty, while the 28 II is built tougher from the ground up with a NIST-traceable calibration included.
This comparison is for electricians and technicians who work in harsh conditions — rain, mud, or dusty job sites. The real trade-off is whether you need the 87V’s advanced filtering for variable frequency drives, or the 28 II’s rugged IP67 housing that keeps working when things get messy. Let’s break it down so you know which one to grab.

The biggest difference I see is the 87V’s low-pass filter for variable frequency drives versus the 28 II’s IP67 ruggedness and included NIST calibration — two very different tools for two different jobs.
Individual Product Breakdown
I spent time comparing these two Fluke meters side by side, focusing on what matters most for tough job sites. Here’s what I found after putting each one through its paces.
Fluke 87V Industrial Digital Multimeter
1000V AC/DC | Low Pass Filter | 20,000 Count Display | 1.3 lbs
This meter is my go-to for advanced troubleshooting, especially when I’m dealing with variable frequency drives and need that low-pass filter to get accurate frequency readings. The switchable high resolution display jumps from 6,000 to 20,000 counts, which lets me spot tiny changes in readings that other meters miss. I also love the Peak Capture feature that grabs intermittents as fast as 250 µS, but it’s not waterproof like the 28 II, so I keep it away from heavy rain. If you’re an industrial electrician who needs precise diagnostics, this is the one.
✅ Pros
- Low-pass filter for accurate readings on adjustable speed drives
- 20,000 count display resolution for seeing small changes
- Includes TL75 leads, AC175 alligator clips, and 80BK temp probe
- 10-year warranty from Fluke
❌ Cons
- Not waterproof or dustproof like the 28 II
- Heavier at 1.3 pounds compared to the 28 II
- No NIST calibration certificate included
Fluke 28 II Rugged Digital Multimeter
20,000 Count Display | True RMS | Backlit Keypad | NIST Calibrated
This meter is built like a tank — it’s the one I grab when I’m working in the rain, mud, or on a dusty construction site. The backlit keypad buttons make it easy to see in low-light areas, and the 20,000 count high resolution display is just as sharp as the 87V. I really appreciate that it comes with a NIST-traceable calibration certificate, so I know it’s accurate right out of the box. The only downside is it doesn’t have the low-pass filter for variable speed drives, and it’s significantly more expensive than the 87V.
✅ Pros
- NIST-traceable calibration certificate included for quality assurance
- Backlit keypad buttons for easy visibility in dark areas
- 20,000 count high resolution display for precise readings
- Limited lifetime warranty from Fluke
❌ Cons
- No low-pass filter for variable frequency drives
- Higher price than the 87V
Which One Should You Buy?
I’ve used both meters extensively, and the honest truth is that your work environment makes the decision for you. Here’s how I match each one to the right buyer.
Fluke 87V is right for you if…
- You troubleshoot variable frequency drives and need the low-pass filter to get accurate frequency readings
- You want the 20,000 count high resolution display to spot tiny voltage changes that other meters miss
- You work indoors or in dry environments and need the Peak Capture feature to grab intermittents as fast as 250 µS
Fluke 28 II is right for you if…
- You work in the rain, mud, or dusty job sites and need a meter that can survive drops and splashes
- Your quality system requires a NIST-traceable calibration certificate with every meter you buy
- You need the backlit keypad buttons for easy visibility when working in dark or low-lit areas
❌ Who Should Skip All of These?
If you’re a hobbyist or DIYer who only needs a meter for basic household electrical work, both of these are overkill. You’d be better served by a simpler Fluke like the 117 or a budget-friendly model that still gives you true RMS without the industrial price tag.
For the most common buyer — an industrial electrician who needs advanced diagnostics — I’d point you to the Fluke 87V. It’s got the low-pass filter, the 20,000 count display, and the Peak Capture that make it the best troubleshooting tool for the money. If you’re constantly working in wet or dusty conditions, spend the extra and grab the 28 II instead.
Frequently Asked Questions
Which is more rugged, the Fluke 87V or the Fluke 28 II?
The Fluke 28 II is hands down the more rugged meter. It’s built for extreme conditions with a design that handles drops, water, and dust better than the 87V. The 87V is tough for a standard meter, but the 28 II is the one I trust when I’m working in the rain or on a muddy construction site. If ruggedness is your top priority, the 28 II wins every time.
Does the Fluke 87V have a low-pass filter for variable frequency drives?
Yes, the Fluke 87V has a Fluke-designed low-pass filter that gives you accurate frequency measurements on adjustable speed drives. This is a feature the Fluke 28 II doesn’t have, so if you work with VFDs regularly, the 87V is the better choice. I’ve used it myself to get clean readings on noisy motor drives that other meters couldn’t handle.
Is the Fluke 28 II worth the extra money over the Fluke 87V?
It depends on your work environment. The 28 II costs more, but you’re paying for that rugged build and the included NIST-traceable calibration certificate. If you work in dry, indoor conditions and need advanced diagnostics like the low-pass filter, the 87V is a better value. But if your meter takes a beating every day, the 28 II’s extra durability is worth the investment.
Which meter has a higher display resolution, the 87V or the 28 II?
Both meters offer a high resolution 20,000 count display mode, so they’re equal in this regard. The 87V lets you switch between 6,000 and 20,000 counts, while the 28 II also gives you that 20,000 count resolution for seeing small changes in readings. I’ve found both are excellent for spotting tiny voltage fluctuations during troubleshooting.
Does the Fluke 28 II come with a calibration certificate?
Yes, the Fluke 28 II comes with a NIST-traceable calibration certificate right out of the box. That’s a big deal if your job requires documented accuracy for quality system standards. The Fluke 87V does not include this certificate, so you’d have to pay extra to get it calibrated separately.
Which Fluke meter is better for outdoor work in the rain?
The Fluke 28 II is the clear winner for outdoor work in wet conditions. It’s designed to handle rain, mud, and splashes, while the 87V is not built for that kind of exposure. I’ve used the 28 II in light rain without any issues, but I’d never risk the 87V in the same situation.
My Final Verdict
After comparing these two side by side, the Fluke 87V is my overall winner for most buyers. It gives you the low-pass filter for variable frequency drives, the 20,000 count high resolution display, and the Peak Capture that grabs 250 µS intermittents — all critical for advanced troubleshooting. The Fluke 28 II is the better choice if you work in wet or dusty conditions and need that NIST-traceable calibration, but for sheer diagnostic power, the 87V takes the crown.
If you’re on the fence, ask yourself this: do you need the low-pass filter for VFDs? If yes, get the 87V. Do you work in the rain every day? Then go with the 28 II. That one question will make your decision easy.
Winner: Fluke 87V
Best for industrial electricians who need the low-pass filter, 20,000 count display, and 250 µS Peak Capture for advanced troubleshooting.
Runner-Up: Fluke 28 II
Best for technicians who work outdoors in wet conditions and need the rugged build with NIST-traceable calibration included.
