Fluke Multimeter Review from a Procurement Manager: Is the 107 Worth It?

I'm the person who signs the P.O. for tool orders at an 87-person electrical service company. I've managed our test-equipment budget (roughly $55,000 a year) for 9 years and documented every purchase in our cost-tracking system.

So when someone asks whether to buy a Fluke multimeter, I don't lead with a spec sheet. I lead with invoice history and one safety near-miss.

Questions I get most:

• Isn't "Fluke multimeter" just brand hype?
• Which Fluke digital multimeter should I choose? Product info and reviews, please.
• Is the Fluke 107 digital multimeter worth it for a maintenance tech?
• Can a Fluke multimeter help me check an adjustable battery charger or a used portable generator?
• How do I use a voltage tester safely?
• Would you ever buy a used Fluke multimeter?
• What about when the budget says "buy cheaper"?

1. Isn't "Fluke multimeter" just brand hype?

I used to think the premium was marketing. Then I ran a six-year audit of our test-instrument spending. The pattern: cheaper alternatives appeared on the P.O. once, and then showed up again as replacements within 18 months. Fluke meters appeared once and then disappeared from the ledger for years.

That's the hidden cost that never appears on a quote. If a meter gives a stable but wrong reading, the next event isn't a return. It's a re-do, a damaged component, or someone trusting a false live/dead status. I can't put a dollar figure on that, but I don't want to explain it to the CFO.

As of January 2025, a Fluke 107 lands around $130 at the distributors I use. It isn't the cheapest sticker in the drawer. It is the lowest total cost. Period.

2. Which Fluke digital multimeter should I choose? Product info and reviews, please.

I'll keep the review short because the real answer is: define the job first. The Fluke lineup is broad, but our P.O. history shows three models covering most work:

• Fluke 107 — compact, CAT III 600 V, AC/DC voltage, resistance, continuity, diode test. Good for daily electrical checks and most maintenance tasks.
• Fluke 115/117 — more advanced, with True-rms, and the 117 adds low-impedance mode and non-contact voltage. Good for commercial troubleshooting.
• Fluke 87V — the industrial workhorse. Good for motor drives, reliability work, and the kind of measurement you double-check before acting.

If I'm ordering for one general electrical crew, I choose the 107. Most of what a tech needs is a trustworthy voltage check, continuity, and a compact size. Save the 87V budget for two or more 107s.

3. Is the Fluke 107 digital multimeter worth it for a maintenance tech?

Yes, if your world is 600 V and below. I bought seven Fluke 107s in Q3 2024 from a distributor at $126 each. The techs initially gave me the "another meter?" look. A month later, three of them had bought one for their personal kit. That tells me more than any spec sheet.

Even after I approved the order, I kept second-guessing. Should I have sprung for the 117s? I didn't relax until the grudging reviews came back. The 107 is not a lab meter, and it's not a clamp meter. For "does this circuit have voltage, is this fuse blown, is this wire open?" it does the job.

One thing I still dislike: the probe tip can work its way out of the holster if you jam it in a bag. (Ugh. Not a safety issue, but annoying.)

4. Can a Fluke multimeter help me check an adjustable battery charger or a used portable generator?

Yes, and I've done both.

The used portable generator story: I found a used portable generator at a liquidation sale. I carried a Fluke 107 out to the loading dock and checked the 120V outlet open-circuit: 125V. Plugged a 1,500W shop heater into it, voltage dropped to 121V. Good enough to buy. The 107 saved me from buying a machine that hums but doesn't produce.

For an adjustable battery charger, the 107 is useful in DC volts. Our shop has a 6/12V charger with an adjustable charge/boost setting. On 12V charge, the meter reads about 13.2V across the clamps. On boost, about 14.4V. If the charger says 2A but voltage never moves, the charger or battery is lying.

Caveat: a general multimeter is not a battery load tester and not a clamp meter. For high cranking current, use a dedicated tester or a clamp meter. Don't force a multimeter to read 50A unless you know its current rating and fuses. (Better yet, don't.)

5. How do I use a voltage tester safely? Is a multimeter a voltage tester?

A multimeter is a voltage tester if you use it like one. The procedure is boring and non-negotiable:

1. Test the tester on a known live source.
2. Test the target.
3. Test the tester again on the known live source.

Why the third step? Because if the tester is faulty and says "dead" when it isn't, you don't get a second chance. You catch it by checking after the test. That's the confirmation check from our safety audit.

The other lesson came from a communication failure on my watch. I said "we need testers for the crew." The person heard "any tester will do." Result: a CAT II meter showed up on a 480V panel job. We now require an IEC 61010-1 category rating on every test-equipment P.O. A Fluke 107, for example, is rated CAT III 600V. That matters.

6. Would you ever buy a used Fluke multimeter? What about a used portable generator?

I've bought a used portable generator. I've never bought a used multimeter for a crew member.

Used generators can be checked under load in 15 minutes. Used meters are a risk because you don't know their history: drops, overloads, moisture, calibration. A used 87V that "was working when it got put away" is not a calibrated instrument. In my procurement system, meters are new. Full stop.

If you're tempted by a used Fluke 107 for a personal kit, ask for calibration or repair records. If there aren't any, treat it as a mystery box. I like mysteries. Not with voltage testers.

7. What about when the budget says "buy cheaper"?

I have mixed feelings about buying premium test tools. Part of me wishes they discounted more. Part of me appreciates that the price I see is the price I pay. No bait-and-switch, no mandatory calibration upgrade turning a $130 quote into $180 after tax and fees.

I've learned to ask "what's NOT included?" before asking the price. A vendor who lists everything upfront—even if the total looks higher—usually costs less in the end. That principle came from an adjustable battery charger quote, ironically. The lower quote had a hidden handling and calibration fee that would have added 18%. The transparent quote didn't.

So is Fluke cheap? No. Is the math defensible? Nine years of P.O. data say yes.
