Why This Comparison Exists (and Why You Should Care)
Here's the thing: I manage procurement for a mid-size industrial services company. Our team of 12 electricians goes through a lot of meters. Over the past 6 years, I've tracked every single purchase in our system—from the cheap $50 options to the top-of-the-line Flukes. And I've learned something uncomfortable: the "best" multimeter isn't always the most expensive one.
When someone asks me, "What is the best Fluke multimeter for electricians?" my first response is always: "Best for what?" The question everyone asks—"Which model has the highest specs?"—is the wrong one. The right question is: "What's the total cost of ownership (TCO) for the work I actually do?"
In this comparison, I'm pitting two of Fluke's most popular models head-to-head: the Fluke 117 (the electrician's workhorse) and the Fluke 87V (the industrial gold standard). We'll look at accuracy, safety, durability, and—critically—where the hidden costs live. Let's dive in.
Dimension 1: Accuracy—Precision vs. Practicality
Fluke 117: 0.1% basic DC accuracy. True-RMS. Auto-sensing Volts function. Good for 95% of electrical work.
Fluke 87V: 0.05% basic DC accuracy. True-RMS. A/D converter. Designed for variable frequency drives (VFDs) and high-noise environments.
Here's what most buyers miss: the 87V's precision is overkill for routine electrical troubleshooting. Unless you're dealing with VFDs, sensitive electronics, or lab-level measurements, you'll never notice the difference.
The 87V is like having a microscope to read a newspaper headline—it's not wrong, but it's wasted capability. For 90% of electricians doing service calls, panel work, or commercial installations, the 117 is more than enough. (And I say that as someone who owns both models.)
Conclusion: For 80-90% of electricians, the 117 wins on value-adjusted accuracy. The 87V only justifies its cost if you're working with VFDs or precision electronics regularly.
Dimension 2: Safety Features—The Silent Differentiator
Fluke 117: CAT III 600V, CAT IV 300V. Auto-volt (detects voltage without a specific range). Low impedance mode to prevent ghost voltage readings.
Fluke 87V: CAT III 1000V, CAT IV 600V. Peak min/max capture. Integrated temperature measurement.
This is where things get interesting. The 117 has something the 87V doesn't: Auto-volt. It automatically detects AC or DC voltage. For a field electrician juggling multiple tools, this is a game-changer. I cannot tell you how many times I've seen an electrician blow a fuse because they forgot to switch modes. (We track that in our incident logs—it's more common than you think.)
On the other hand, the 87V's safety rating is higher: CAT IV 600V vs. CAT IV 300V. If you're working on utility-level gear or high-energy circuits, that's a legitimate safety margin you shouldn't compromise on. But for commercial and residential work? The 117's safety rating covers almost everything you'll encounter.
What most people don't realize is that safety isn't just about ratings—it's about how the meter handles real-world slip-ups. Both models handle input protection well, but the 117's smart features can prevent user error before it happens.
Conclusion: For safety in typical electrical work, the 117's smart features (Auto-volt) give it an edge. The 87V wins if you need the absolute highest CAT rating for high-energy environments.
Dimension 3: Durability & Build—The Long Game
Fluke 117: Drop-tested to 3 meters. Overvoltage protection. 1-year warranty on most models (included).
Fluke 87V: Drop-tested to 3 meters. IP67 rated (dust and waterproof). 3-year warranty (included).
I wish I had tracked our repair costs more carefully over the years. What I can say anecdotally is that our electricians have dropped both models off ladders, trucks, and scaffolds. The 87V survives better in wet conditions—IP67 vs. the 117's standard protection. But for indoor work? The 117 holds up fine.
Here's the inside scoop vendors won't tell you: the longer warranty on the 87V isn't free—it's built into the price. The 117's shorter warranty assumes you'll replace it faster, but for most of our team, the 117 lasted 4-5 years before needing a replacement. The 87V is still running after 7+ years. That matters for TCO.
Conclusion: The 87V's durability edges win for long-term ownership. The 117 is no slouch, but if you need a meter that can survive rain and drops, the 87V is the better bet.
Dimension 4: Total Cost of Ownership (The Surprising Winner)
Let's do the math.
Fluke 117: ~$180-$220 as of January 2025 (pricing varies).
Fluke 87V: ~$400-$450 as of January 2025 (pricing varies).
Looking at that, the 87V is 2x the upfront cost. But here's the kicker: when I analyzed our team's spending over 6 years, the 87V's TCO was roughly 60% higher than the 117, not 100%. Why? Because the 87V lasted longer, required fewer repairs, and had superior resale value (yes, we've sold used meters).
But here's what the numbers don't show: the cost of having the wrong tool. If an electrician needs to measure VFDs and they're stuck with a standard meter, they lose time, risk mistakes, and frustrate the client. That's a hidden cost no spreadsheet captures easily.
Every cost analysis pointed to the 117 being the "budget" option. My gut said the 87V might be better for our situation. I went with my gut on a trial—bought 3 of each. Turns out, for our team's work (mostly commercial and light industrial), the 117 was the right call. The 87V was overkill and sat in the toolbox most days. (Note to self: actually track usage next time.)
Conclusion: For most electricians, the 117 is the TCO winner. The 87V only pays off if you need its unique features (VFD support, higher CAT rating) regularly.
Final Verdict: When to Buy Which
There's no single "best" Fluke multimeter for all electricians. The answer depends on your situation:
Buy the Fluke 117 if:
- You do commercial, residential, or light industrial electrical work.
- You need a reliable, accurate meter for 95% of your jobs.
- You value features like Auto-volt that prevent user error.
- Your budget is under $250.
- You're okay with a standard warranty (1 year).
Buy the Fluke 87V if:
- You regularly work with VFDs, high-noise environments, or precision electronics.
- You need the highest safety ratings (CAT IV 600V).
- You work in harsh conditions (wet, dusty, drop-prone).
- You plan to keep the meter for 10+ years and want a 3-year warranty.
- Your budget allows for $400+.
For the majority of electricians—and I mean 8 out of 10—the Fluke 117 is the better investment. It gives you 90% of the capability at 50% of the cost. The 87V is a specialist tool for specialist work. Don't let marketing convince you otherwise.
