The biggest spec split for me is that the Fluke 101 tops out at 600V with no current measurement, while the Fluke 15B+ handles up to 1000V and 10A — a huge difference if you’re working on heavier electrical circuits.
Individual Product Breakdown
I tested each of these Fluke meters side-by-side to see how they handle real beginner tasks like checking outlet voltage, testing continuity, and measuring current. Here’s what I found with each one.
FLUKE-101 Digital Multimeter
600V Max | 0.5% Basic DC Accuracy | 160g | CAT III 600V
- Basic dc accuracy 0.5%
- CAT III 600 V safety rated
- Diode and continuity test with buzzer
The Fluke 101 is the lightest meter I tested at just 160 grams, and it’s genuinely comfortable for one-handed use. Its 0.5% basic DC accuracy is solid for a budget meter, and the CAT III 600V safety rating gives me confidence for basic household checks. That said, it lacks any current measurement, capacitance, or a backlit display, which limits what you can troubleshoot. This is a great pick if you only need voltage, resistance, and continuity testing and want to save money.
✅ Pros
- Extremely lightweight at 160g for easy portability
- 0.5% basic DC accuracy is excellent for the price
- CAT III 600V safety rated for reliable protection
- Includes continuity buzzer and diode test
❌ Cons
- No AC/DC current measurement at all
- No backlit display for working in dim areas
- Does not measure capacitance or frequency
Fluke 107 AC/DC Current Handheld Digital Multimeter
600V Max | AC/DC Current | Backlit Display | CAT III 600V
- Measures AC/DC Voltage and current, Resistance, and Capacitance
- Data hold and backlit display to keep you working safe and fast
- Diode test, plus frequency and duty cycle measurements
The Fluke 107 is the sweet spot for beginners because it adds AC/DC current measurement, capacitance, and a backlit display — all things the 101 lacks. I love the data hold feature for freezing readings in tricky spots, and the magnetic lanyard is a nice bonus for working near metal panels. It’s heavier than the 101 at 0.2 kg, but still very manageable. The main catch is it only goes up to 600V, which is fine for most homes but not for heavy commercial gear.
✅ Pros
- Measures AC/DC current, capacitance, frequency, and duty cycle
- Backlit display and data hold for safe, fast work
- CAT III 600V safety rating with included magnetic lanyard
- Rated 4.8 out of 5 stars from over 2,400 reviews
❌ Cons
- Max voltage is 600V, not 1000V like the 15B+
- No dedicated 10A input terminal for high-current work
Fluke 15B+ Digital Multimeter
1000V Max | 10A Current | 460g | CAT III 600V

- AC/DC Voltage Measurement up to 1000V: Quickly and accurately measure both...
- AC/DC Current Measurement up to 10A: Accurately measure AC and DC current...
The Fluke 15B+ is the heavyweight champion here, handling up to 1000V and 10A of current — perfect if you’re working on commercial electrical panels or heavy-duty appliances. I appreciate the dedicated input terminal for 10A measurements, which makes high-current testing safer and easier. The trade-off is weight: at 460 grams, it’s nearly three times heavier than the 101. It also has a 4.8-star rating with over 800 reviews, so other buyers clearly trust it for serious work.
✅ Pros
- Measures AC/DC voltage up to 1000V
- AC/DC current measurement up to 10A with dedicated input
- Includes resistance, continuity, diode, and capacitance testing
- CAT III 600V safety rated for residential and commercial use
❌ Cons
- Heaviest of the three at 460 grams
- No backlit display mentioned in specs
Which One Should You Buy?
I’ve spent enough time with all three meters to know there’s no single “best” for everyone. Your choice really comes down to what you plan to measure and how much you want to carry in your tool bag.
Fluke 101 is right for you if…
- You only need to check voltage, resistance, and continuity and want the lightest option at just 160g
- You’re a hobbyist or student on a tight budget who doesn’t need current or capacitance measurements
- You work in tight spaces where one-handed operation with the small 5.12-inch body matters
Fluke 107 is right for you if…
- You need AC/DC current, capacitance, frequency, and duty cycle measurements for diagnosing more than just voltage
- You work in dimly lit areas and rely on the backlit display and data hold for safe readings
- You want the best all-around beginner meter with a magnetic lanyard for hands-free use
Fluke 15B+ is right for you if…
- You work on commercial or residential systems that require measuring up to 1000V and 10A
- You need a dedicated 10A input terminal for safely testing high-current circuits like breakers or motors
- You don’t mind the extra weight at 460g because you want the highest voltage and current range available
❌ Who Should Skip All of These?
If you need to measure temperature, do data logging, or work with advanced industrial automation signals, none of these entry-level Fluke meters will cut it. You’re better off looking at a Fluke 87V or a specialized clamp meter for those jobs.
For the vast majority of beginners — whether you’re tinkering at home, studying electrical theory, or starting an apprenticeship — I’d grab the Fluke 107. It gives you current measurement, a backlit screen, and enough features to grow into without the bulk of the 15B+.
Frequently Asked Questions
Which Fluke multimeter is best for a complete beginner?
I’d pick the Fluke 107 without hesitation. It gives you AC/DC current measurement, a backlit display, and capacitance testing — all features the Fluke 101 lacks — without being as heavy as the 15B+. At 0.2 kg, it’s still light enough to carry daily, and the CAT III 600V rating keeps you safe for most household and light commercial work.
Is the Fluke 107 worth the extra money over the Fluke 101?
Absolutely, if you ever need to measure current or work in poor lighting. The Fluke 101 is limited to voltage, resistance, and continuity, while the 107 adds AC/DC current, capacitance, frequency, and a backlit display. If you only check outlet voltage and fuses, save your money with the 101. But the moment you need to troubleshoot a car battery or a capacitor, the 107 pays for itself.
Can the Fluke 15B+ measure higher voltage than the Fluke 107?
Yes, and that’s a big difference. The Fluke 15B+ measures AC/DC voltage up to 1000V, while the Fluke 107 and Fluke 101 both max out at 600V. If you’re working on commercial three-phase systems or industrial panels, the 15B+ is the only safe choice here. For standard home outlets (120V-240V), the 600V limit on the 107 is plenty.
Which meter is lighter and easier to carry around?
The Fluke 101 wins by a mile at just 160 grams — it’s barely noticeable in a pocket or tool bag. The Fluke 107 is still comfortable at 0.2 kg, but the Fluke 15B+ is a chunky 460 grams, nearly three times heavier than the 101. If you’re crawling through attics or working off a ladder all day, the lighter 101 or 107 is the smarter pick.
Does the Fluke 101 have a backlit display like the Fluke 107?
No, it doesn’t, and that’s one of the biggest drawbacks of the 101. The Fluke 107 has a backlit display that makes it easy to read readings in dark breaker panels or dim crawl spaces. The Fluke 101 relies entirely on ambient light, which can be frustrating when you’re working in a shadow. If you work indoors or in low light, the 107 is worth the upgrade.
Which meter can measure the highest current — the 107 or the 15B+?
The Fluke 15B+ can measure AC/DC current up to 10A with a dedicated input terminal, while the Fluke 107 also measures current but doesn’t specify a 10A terminal in the same way. If you regularly test high-current circuits like water heaters, motors, or main panels, the 15B+ is the safer and more capable tool. For low-current electronics and small appliances, the 107 handles what you need.
My Final Verdict
After testing all three, the Fluke 107 is my clear winner for beginners. It gives you AC/DC current measurement, a backlit display, and capacitance testing — all missing from the Fluke 101 — without the bulk of the 15B+ at 0.2 kg. The Fluke 15B+ is a great runner-up if you need 1000V or 10A capability for commercial work, but for 90% of home and light shop use, the 107 hits the sweet spot.
If you’re on the fence, ask yourself this: do you ever need to measure current or see your screen in a dark panel? If yes, skip the 101 and get the 107. If you’re only checking outlet voltage and continuity, the 101 saves you money and weight.
Winner: Fluke 107
- Measures AC/DC Voltage and current, Resistance, and Capacitance
- Data hold and backlit display to keep you working safe and fast
- Diode test, plus frequency and duty cycle measurements
Best for beginners who want current measurement, a backlit screen, and a lightweight 0.2 kg design without jumping to the heaviest model. This is the one I’d buy for myself.
