If you’re an industrial electrician or technician, you already know the Fluke 87V is the gold standard for troubleshooting. But the real question is whether you should grab the standalone Fluke 87V or the Fluke 87V/IMSK kit that throws in the i400 current clamp and a pile of accessories.
I’ve spent years working with both setups, and this comparison is for anyone who needs to measure up to 1000 V AC/DC and capture intermittent faults as fast as 250 µs. The key trade-off is whether the included i400 clamp (handling up to 400 A AC) justifies the extra cost — and I’ll show you exactly how that plays out in real jobs.

The biggest difference is the i400 clamp in the 87V/IMSK kit, which lets you measure AC current up to 400 A — something the standalone 87V can’t do without buying an extra accessory.
Individual Product Breakdown
I took a close look at both kits to see how they handle real-world industrial troubleshooting — from chasing intermittent faults to measuring high-current circuits.

This kit is my top pick if you’re doing industrial work and need to measure both voltage and current on the same job. The included i400 clamp converts the 87V into a clamp meter that handles AC current up to 400 A, which is perfect for motor circuits and panel troubleshooting. The 87V itself captures intermittent faults as fast as 250 µs with Peak Capture, and the kit throws in a temperature probe, test leads, and alligator clips so you’re ready to go out of the box. My only gripe is that the clamp is AC-only — if you need DC current measurements, you’ll need a different accessory.
✅ Pros
- i400 clamp measures AC current up to 400 A
- Includes temp probe, test leads, and alligator clips
- Peak Capture catches glitches as fast as 250 µs
- Limited lifetime warranty on the meter
❌ Cons
- i400 clamp only measures AC, not DC current
- Bulky kit takes up more space in your bag

If you already own a current clamp or rarely need to measure current above 10 A, the standalone Fluke 87V is the smarter buy. It’s the same core meter with the same 250 µs Peak Capture and switchable resolution up to 20,000 counts, plus the built-in low-pass filter that’s a lifesaver when troubleshooting variable frequency drives. The kit includes TL75 test leads, AC175 alligator clips, and the 80BK temperature probe, so you’re still getting a complete setup. The downside is you don’t get the i400 clamp, so you’ll have to buy one separately if you need to measure AC current beyond the meter’s internal 10 A range.
✅ Pros
- Low-pass filter for accurate readings on VFDs
- Switchable resolution from 6,000 to 20,000 counts
- Includes temp probe, leads, and alligator clips
- Lighter at 1.3 lbs — easier to carry
❌ Cons
- No current clamp included — need to buy separately
- Internal meter only measures up to 10 A AC
Which One Should You Buy?
Both of these Fluke 87V setups are built for serious industrial work, but the right choice comes down to whether you already own a current clamp or need one in the box. Here’s how I’d match each kit to a specific buyer.
Fluke 87V/IMSK Industrial Digital Multimeter with Fluke i400 Current Clamp Kit is right for you if…
- You regularly troubleshoot motor circuits and need to measure AC current up to 400 A without buying a separate clamp
- You want a complete all-in-one kit with temp probe, test leads, and alligator clips so you’re ready the day it arrives
- You’re starting from scratch and prefer getting the clamp and meter in one package rather than hunting for accessories later
Fluke 87V Industrial Digital Multimeter is right for you if…
- You already own a current clamp and only need the best handheld meter for voltage, resistance, and temperature measurements
- You troubleshoot variable frequency drives and need the built-in low-pass filter for accurate frequency readings on ASDs
- You want a lighter meter at 1.3 lbs that’s easier to carry in a tool bag all day
❌ Who Should Skip All of These?
If you mostly work on residential or light commercial electrical systems and rarely need to measure above 600 V, a less expensive meter like the Fluke 117 or 179 will save you a lot of money. You also don’t need the 250 µs Peak Capture or 20,000-count resolution unless you’re chasing intermittent faults on industrial equipment.
For most industrial electricians and technicians, I recommend the Fluke 87V/IMSK kit — the included i400 clamp gives you AC current measurements up to 400 A right out of the box, and you get the same legendary 87V meter with its 250 µs Peak Capture and low-pass filter. It’s the complete package that saves you from buying accessories later.
Frequently Asked Questions
Which is better for industrial troubleshooting — the Fluke 87V/IMSK kit or the standalone Fluke 87V?
The Fluke 87V/IMSK kit is better for most industrial troubleshooting because it includes the i400 current clamp that measures AC current up to 400 A. That clamp alone can save you from buying a separate accessory later. The standalone 87V is the same core meter, but you’ll need to buy a clamp separately if you ever need to measure current beyond the meter’s internal 10 A range.
Is the Fluke 87V/IMSK kit worth the extra money over the standalone 87V?
Yes, if you regularly measure AC current above 10 A on motor circuits, panels, or industrial equipment. The i400 clamp in the kit handles up to 400 A AC, and buying that clamp separately would cost you nearly as much as the price difference between the two setups. If you never measure current with a clamp, you can skip the kit and save your money.
Can the Fluke 87V/IMSK measure DC current with the included clamp?
No — the i400 current clamp that comes in the 87V/IMSK kit only measures AC current, not DC. If you need to measure DC current with a clamp, you’ll need to buy a different accessory like the Fluke i410 or i250. The standalone 87V meter itself can measure DC current up to 10 A through the test leads, just not through the included clamp.
Does the standalone Fluke 87V include a temperature probe?
Yes, the standalone Fluke 87V comes with the 80BK temperature probe, along with TL75 test leads and AC175 alligator clips. So both the kit and the standalone meter give you the ability to measure temperature right out of the box. The big difference is the i400 current clamp that only comes in the 87V/IMSK kit.
Which one has the low-pass filter for variable frequency drives?
Both the Fluke 87V/IMSK kit and the standalone Fluke 87V have the built-in low-pass filter for accurate frequency measurements on adjustable speed drives. That’s a standard feature of the Fluke 87V meter itself, regardless of which kit you buy. So if you troubleshoot VFDs, either option will work fine.
Which Fluke 87V setup is lighter and easier to carry in a tool bag?
The standalone Fluke 87V is lighter at 1.3 pounds, while the 87V/IMSK kit weighs about 355 grams for just the meter — but the kit includes the i400 clamp and extra accessories that add bulk. If you’re carrying this in a tool bag all day and already own a current clamp, the standalone 87V is the more portable choice.
My Final Verdict
The Fluke 87V/IMSK kit is my clear winner for industrial troubleshooting because it gives you the same legendary 87V meter with 250 µs Peak Capture plus the i400 clamp that measures AC current up to 400 A — all in one package. The standalone Fluke 87V is the runner-up and the better choice if you already own a current clamp and just need the meter with its low-pass filter for VFD work. If you’re starting fresh or upgrading your whole toolkit, the 87V/IMSK saves you from buying the clamp later.
If you’re still on the fence, ask yourself one question: do you ever need to measure AC current above 10 A on motor circuits or panels? If yes, get the kit. If no, save your money and grab the standalone 87V.
