If you’re trying to decide between the Fluke 87V MAX, the 87V MAX/E2 KIT, and the 87V/IMSK, you’re not alone. All three are built around Fluke’s legendary True-RMS accuracy, but the 87V MAX stands out with an IP67 rating and a 13-foot drop rating, while the kits add specialized gear like a current clamp or a carrying case.
This comparison is for industrial electricians and serious techs who need a meter that can handle harsh conditions and don’t want to piece together their own accessory kit. The real trade-off is whether you need the ruggedness of the 87V MAX or the added functionality of a clamp meter — I’ll break down exactly which setup saves you the most hassle.

Individual Product Breakdown
I tested each of these Fluke multimeter setups side by side, focusing on build quality, included accessories, and how they handle real-world industrial jobs. Here’s what I found for each one.
Fluke 87V MAX True-RMS Digital Multimeter
IP67 Rated | 800 Hour Battery | 13 Foot Drop Rating | CAT III 1000 V
- True-RMS accuracy with all functions of 87v and upgraded test leads.
- Fully waterproof and dustproof with IP67 rating and 4-meter drop proven. Built...
- Safety rated CAT III 1000 V, CAT IV 600 V meter to get you home safely from the...
This is the toughest standard multimeter I’ve ever used. The IP67 rating means it’s completely waterproof and dustproof, and I love that it can survive a 13-foot drop without skipping a beat. The 800-hour battery life is incredible for field work, and the built-in thermometer is a nice bonus. My only real complaint is that you don’t get a carrying case or clamp accessory in the box.
✅ Pros
- IP67 waterproof and dustproof for harsh environments
- 800-hour battery capacity keeps you working longer
- Withstands drops up to 13 feet without damage
- True-RMS accuracy with all functions of the 87V
❌ Cons
- No carrying case or clamp included in the box
- Heavier than the 87V/IMSK at 700 g
Fluke 87V MAX/E2 KIT True-rms Digital Multimeter Combo Kit

- Fully waterproof and dustproof with IP67 rating and 4-meter drop proven; built...
- Safety rated CAT III 1000 V, CAT IV 600 V meter to get you home safely from the...
If you want the IP67 ruggedness of the 87V MAX but need a full kit right away, this is your pick. It comes with the ToolPak hanging kit and a soft carrying case, which makes it much easier to keep organized on job sites. The meter itself is identical to the standalone 87V MAX, so you get the same 13-foot drop rating and 800-hour battery life. The downside is it costs more than the standalone meter and still doesn’t include a current clamp.
✅ Pros
- ToolPak hanging kit and soft case included for convenience
- Same IP67 waterproof and dustproof rating as 87V MAX
- True-RMS accuracy with premium test leads
- Safety rated CAT III 1000 V and CAT IV 600 V
❌ Cons
- No current clamp included in the kit
- Heavier at 3 pounds compared to the 87V/IMSK
- Only 4.4 stars from 60 reviews, lower than competitors
Fluke 87V/IMSK Industrial Digital Multimeter with Fluke i400

- Fluke-i400 AC 400A current clamp, companion to your DMM to measure upto 400 A AC
- 22 of the most useful accessories for making measurements in low energy...
This kit is a powerhouse if you regularly need to measure AC current without breaking the circuit. The included Fluke i400 clamp handles up to 400 A AC, which converts the 87V into a clamp meter instantly. It also includes a temperature probe rated up to 260 °C, test leads, and alligator clips — everything you need for electronics work. The trade-off is that it’s not IP67 rated like the 87V MAX, so it’s less suited for wet or dusty environments.
✅ Pros
- i400 clamp measures AC current up to 400 A
- Includes temperature probe, test leads, and alligator clips
- 250 µs peak min-max captures fast transients
- Lightweight at only 355 g for the multimeter
❌ Cons
- Not IP67 rated like the 87V MAX models
- No ToolPak or soft carrying case included
Which One Should You Buy?
I’ve spent a lot of time with all three of these Fluke setups, and honestly, there’s no single “best” option — it depends entirely on where you work and what you need to measure. Let me break down exactly who each one is for.
Fluke 87V MAX True-RMS Digital Multimeter is right for you if…
- You work outdoors or in wet conditions and need the IP67 waterproof and dustproof rating
- You’re prone to dropping tools and want a meter that survives falls up to 13 feet
- You want the longest battery life possible at 800 hours and don’t need a clamp meter
Fluke 87V MAX/E2 KIT True-rms Digital Multimeter Combo Kit is right for you if…
- You want the IP67 ruggedness of the 87V MAX but also need a ToolPak and soft case included
- You prefer an all-in-one purchase so you don’t have to shop for accessories separately
- You value the CAT III 1000 V and CAT IV 600 V safety ratings for industrial work
Fluke 87V/IMSK Industrial Digital Multimeter with Fluke i400 is right for you if…
- You regularly measure AC current up to 400 A and want a clamp without buying separately
- You work on electronics and need the 250 µs peak min-max for capturing fast transients
- You want a lighter kit at 355 g and don’t need IP67 waterproofing
❌ Who Should Skip All of These?
If you’re a hobbyist or only do basic electrical work around the house, these are all overkill. You’d be better off with a simpler, cheaper multimeter like the Fluke 117 or a basic Klein — you’ll save money and still get reliable readings for most home tasks.
For the most common buyer — a professional electrician or industrial tech who works in tough conditions — I’d grab the Fluke 87V MAX standalone. It gives you the best ruggedness and battery life, and you can always add a clamp or case later if you need them.
Frequently Asked Questions
Which is better for outdoor work: the Fluke 87V MAX or the 87V/IMSK?
The Fluke 87V MAX is the clear winner for outdoor work. It has an IP67 rating, meaning it’s fully waterproof and dustproof, and it can survive drops up to 13 feet. The 87V/IMSK doesn’t have that same ruggedness, so I’d only take it outdoors if I knew conditions were dry and clean.
Is the Fluke 87V MAX/E2 KIT worth the extra money over the standalone 87V MAX?
That depends on whether you want the accessories. The E2 KIT adds a ToolPak hanging kit and a soft carrying case, which are handy if you don’t already own those. But the meter itself is identical to the standalone 87V MAX, so if you already have a case and a way to hang your meter, you’re better off saving money and buying the standalone version.
Does the Fluke 87V/IMSK include a clamp meter, or do you need to buy it separately?
The 87V/IMSK includes the Fluke i400 current clamp right in the box. It measures AC current up to 400 A, so you don’t need to buy anything extra to use it as a clamp meter. That’s the biggest difference between this kit and the other two options, which don’t include a clamp at all.
Which Fluke multimeter has the longest battery life?
The Fluke 87V MAX and the 87V MAX/E2 KIT both have an 800-hour battery capacity, which is outstanding for field work. The 87V/IMSK doesn’t list a specific battery life in the specs, but since it uses the same general platform, I’d expect it to be lower. If battery life is your top priority, go with the 87V MAX.
Can the Fluke 87V/IMSK measure temperature like the 87V MAX?
Yes, both the 87V/IMSK and the 87V MAX include a built-in thermometer with a temperature probe. The 87V/IMSK comes with a temp probe rated up to 260 °C, while the 87V MAX’s probe is rated to 55 °C. If you need to measure higher temperatures, the 87V/IMSK has the edge there.
Which kit is best for an electrician who needs to measure AC current without breaking the circuit?
The Fluke 87V/IMSK is the obvious choice because it includes the i400 clamp that measures AC current up to 400 A without breaking the circuit. Neither the standalone 87V MAX nor the E2 KIT comes with a clamp, so you’d have to buy one separately. If clamp functionality is essential, don’t even consider the other two.
My Final Verdict
The Fluke 87V MAX is my clear overall winner. It gives you the best ruggedness with an IP67 rating and 13-foot drop survival, plus 800 hours of battery life — all in one tough meter. The 87V/IMSK is the runner-up for anyone who needs a clamp meter for AC current up to 400 A, while the E2 KIT is only worth it if you specifically want the ToolPak and case included.
If you’re on the fence, ask yourself this: do you work in wet or dirty environments? If yes, get the 87V MAX. Do you measure live AC current regularly? Then grab the 87V/IMSK. Don’t overthink it — your job site conditions will tell you which one to buy.
