If you’re an industrial maintenance tech trying to decide between the Fluke 87V, the Fluke 179, or the Fluke 1587 FC, you’ve got a real dilemma. I’ve spent time with all three, and each one serves a different purpose — the 1587 FC is a 2-in-1 insulation multimeter that measures up to 1000 volts, while the 87V is the gold standard for advanced troubleshooting with its low-pass filter for variable frequency drives.
This comparison is for anyone who needs a meter for daily plant-floor work, motor testing, or electrical panel troubleshooting. The key trade-off here is insulation testing versus pure multimeter precision, and I’ll help you figure out which one actually saves you time and money. Let’s break it down.

The Fluke 1587 FC is a beast for anyone who does motor insulation testing regularly. I love that it combines a full-featured multimeter with insulation resistance testing up to 1000 volts, and the PI/DAR graphing through the Fluke Connect app is a big improvement for spotting problems faster. The memory storage through the mobile app eliminates writing down results, which saves me time and reduces errors on the job. My only gripe is that it’s the most expensive of the three, and at 300 grams it feels light but the bulk of the insulation function adds size.
✅ Pros
- 2-in-1 design saves carrying two separate tools
- PI/DAR graphing with Trend It identifies problems faster
- Temperature compensation through app for accurate baselines
- Fluke Connect app stores data for historical tracking
❌ Cons
- Premium price tag compared to the 87V and 179
- Overkill if you only need a standard multimeter

The Fluke 87V is the meter I grab most often for plant-floor troubleshooting. Its low-pass filter is a lifesaver when I’m working on variable frequency drives, and the Peak Capture feature catches intermittents as fast as 250 microseconds. I also appreciate the switchable high display resolution from 6000 to 20,000 counts, which lets me see tiny changes in readings that other meters miss. It’s a bit heavier at 1.3 pounds compared to the 1587 FC, but that rugged build gives me confidence it’ll survive drops on the job.
✅ Pros
- Low-pass filter for accurate frequency measurements on ASDs
- 20,000-count resolution for seeing small changes
- Peak Capture catches intermittents at 250 µS
- CAT III 1000V / CAT IV 600V safety rated
❌ Cons
- No insulation testing capability like the 1587 FC
- Heavier at 1.3 pounds compared to the lighter 179

The Fluke 179 is a solid all-around meter that punches above its weight for general maintenance work. I really like the built-in thermometer that measures up to 400°C with the included thermocouple, which is rare to find at this level. It gives you True-RMS readings, a backlit display, and Min/Max-Average recording, all in a compact package that weighs just 300 grams. The downside is it lacks the advanced motor drive filtering of the 87V and the insulation testing of the 1587 FC, so it’s not for specialized industrial tasks.
✅ Pros
- Built-in thermometer with included temperature probe
- True-RMS for accurate AC measurements on non-linear loads
- Lightweight at 300 grams for easy carrying
- Backlit display and analog bar graph for quick readings
❌ Cons
- No low-pass filter for variable frequency drives
- Lower resolution than the 87V’s 20,000-count display
Which One Should You Buy?
I’ve spent enough time with all three to know that the “best” choice really comes down to what you’re troubleshooting day in and day out. Let me help you match the right meter to your specific work.
Fluke 1587 FC is right for you if…
- You regularly test motor insulation and need PI/DAR graphing to identify problems faster
- You want to log and track insulation resistance data over time using the Fluke Connect app
- You need a 2-in-1 tool that handles both standard multimeter tasks and insulation testing up to 1000 volts
Fluke 87V is right for you if…
- You troubleshoot variable frequency drives and need the low-pass filter for accurate frequency readings
- You chase intermittent faults and need Peak Capture that catches glitches as fast as 250 microseconds
- You want high-resolution readings up to 20,000 counts to spot small changes in voltage or current
Fluke 179 is right for you if…
- You need a True-RMS meter with a built-in thermometer that measures up to 400°C for HVAC or panel checks
- You want a lightweight 300-gram meter for everyday general maintenance without specialized features
- You’re on a tighter budget but still want Fluke reliability and a 10-year warranty
❌ Who Should Skip All of These?
If your work is strictly residential electrical or basic DIY projects around the house, you’re probably overpaying for industrial-grade features you’ll never use. A simpler meter like the Fluke 117 or even a budget-friendly Klein would serve you just fine without the extra cost.
For most industrial maintenance techs, my clearest recommendation is the Fluke 87V — it’s the most versatile workhorse that handles 90% of plant-floor troubleshooting, and its low-pass filter and high-resolution display give you capabilities you’ll actually use every day.
Frequently Asked Questions
Which is better for industrial maintenance, the Fluke 87V or the Fluke 1587 FC?
For general industrial maintenance, I’d pick the Fluke 87V because it’s the more versatile troubleshooting tool. Its low-pass filter handles variable frequency drives, and the 20,000-count resolution lets me see tiny changes in readings that the 1587 FC can’t match. The 1587 FC only makes sense if you specifically need insulation testing up to 1000 volts with PI/DAR graphing.
Is the Fluke 1587 FC worth the extra money over the Fluke 87V?
Only if you regularly test motor windings or cable insulation. The 1587 FC is a 2-in-1 tool that combines a multimeter with an insulation tester, and the Fluke Connect app with temperature compensation helps you track resistance trends over time. If you never do insulation testing, you’re paying for a feature you won’t use — stick with the 87V.
Can the Fluke 179 handle industrial maintenance tasks?
It can handle light industrial work like checking voltage, continuity, and temperature up to 400°C with its built-in thermometer. But it lacks the low-pass filter for variable frequency drives and the high 20,000-count resolution of the 87V, so it’s better suited for HVAC, commercial, or general facility maintenance rather than heavy industrial troubleshooting.
Which Fluke meter has the best warranty?
Both the Fluke 87V and the Fluke 179 come with a 10-year warranty, which is outstanding for industrial tools. The Fluke 1587 FC only has a 3-year warranty, which is a noticeable difference given its higher price point. That longer warranty on the 87V gives me more confidence for daily use on the plant floor.
What’s the difference between the Fluke 87V and the Fluke 179?
The big differences are the 87V’s low-pass filter for motor drives, its Peak Capture that catches faults at 250 microseconds, and a switchable display up to 20,000 counts. The 179 weighs only 300 grams compared to the 87V’s 1.3 pounds, and it includes a built-in thermometer with a temperature probe, which the 87V doesn’t have standard.
Should I buy the Fluke 1587 FC or just get a separate insulation tester and multimeter?
I’d go with the 1587 FC if you want one tool that does both jobs and you value the Fluke Connect app for logging PI/DAR data over time. But if you already own a solid multimeter like the Fluke 87V, buying a standalone insulation tester separately might give you more flexibility and better specs in each tool for the same money.
My Final Verdict
My clear overall winner for industrial maintenance is the Fluke 87V — it’s the most versatile and capable meter for the widest range of plant-floor tasks. Its low-pass filter for variable frequency drives and 20,000-count resolution give it an edge that the other two can’t touch for everyday troubleshooting. The Fluke 1587 FC is the runner-up for anyone who specifically needs insulation testing with PI/DAR graphing, while the Fluke 179 is the smart choice for general maintenance on a budget.
If you’re still on the fence, ask yourself one question: do you troubleshoot motor drives and intermittent faults, or do you test motor insulation? If it’s the former, buy the 87V. If it’s the latter, the 1587 FC is your tool. The 179 is only the right call if you need a solid basic meter with a built-in thermometer and don’t need advanced features.
