Fluke 113 vs Fluke 107 Multimeter: Best Utility Tool for Field Work?
If you’re a utility worker trying to choose between the Fluke 113 and the Fluke 107, you’re looking at two solid meters with different strengths. The Fluke 113 gives you True-RMS accuracy with CAT III 600V / CAT IV 300V safety, while the Fluke 107 packs AC/DC current measurement up to 10 amps into a palm-sized body that weighs just 0.2 kilograms.
This comparison is for electricians, technicians, and field workers who need a reliable meter for daily troubleshooting. The big trade-off here is advanced utility features versus compact portability. I’ll break down exactly which one fits your work style better.

Full Specs Comparison
I’ve lined up every spec from both meters side by side so you can see exactly what each one brings to the job site. Here’s how the Fluke 113 and Fluke 107 stack up.
Fluke 113 True-RMS Utility Multimeter
True RMS | 600V AC/DC | CAT IV 300V | 0.4 kg
- Digital multimeter measures AC/DC voltage, resistance, and capacitance and...
- True RMS meter provides accurate readings when measuring linear or...
- Simultaneously checks for voltage and continuity
The Fluke 113 is my top pick for utility work because it gives you True-RMS accuracy on top of a CAT IV 300V safety rating โ that’s serious protection for troubleshooting near the service entrance. I love that it measures capacitance up to 9,999 ยตF and has a Max/Min function to catch voltage spikes, which is huge for diagnosing fluctuating loads. The 6000-count backlit display and 300-hour battery life mean I’m not squinting or swapping batteries every week. My only gripe is it doesn’t measure AC/DC current, so you’ll need a clamp accessory for amp readings.
โ Pros
- True-RMS for accurate readings on nonlinear loads
- CAT IV 300V safety for higher-risk environments
- Capacitance to 9,999 ยตF โ great for motor start caps
- 300-hour battery life with sleep mode
โ Cons
- No AC/DC current measurement
- Weighs 0.4 kg โ heavier than the 107
Fluke 107 AC/DC Current Handheld Digital Multimeter
AC/DC Current to 10A | Frequency & Duty Cycle | 0.2 kg | 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 meter I grab when I need to check amps on the fly โ it measures AC and DC current all the way up to 10 amps, which the 113 simply can’t do. It’s unbelievably compact at just 0.2 kg and fits right in my palm, plus the magnetic lanyard keeps it handy on metal panels. I also appreciate the frequency and duty cycle measurements for troubleshooting variable frequency drives. The trade-off is it lacks True-RMS and only has a CAT III 600V rating (no CAT IV), so it’s better for lighter commercial work than heavy utility jobs.
โ Pros
- Measures AC and DC current up to 10A
- Ultra-light at 0.2 kg โ easy to carry all day
- Frequency and duty cycle for motor work
- 4.8 out of 5 stars from 2,484 reviews
โ Cons
- No True-RMS โ less accurate on nonlinear loads
- No CAT IV safety rating for utility panels
Which One Should You Buy?
I’ve spent a lot of time with both meters, and honestly, the right pick comes down to what you’re troubleshooting most often. Let me break it down by buyer type.
Fluke 113 True-RMS Utility Multimeter is right for you if…
- You work near utility panels and need CAT IV 300V safety protection
- You diagnose nonlinear loads like VFDs or LED drivers and need True-RMS accuracy
- You test capacitors up to 9,999 ยตF on motors or HVAC equipment regularly
Fluke 107 AC/DC Current Handheld Digital Multimeter is right for you if…
- You need to measure AC or DC current up to 10 amps without a separate clamp
- You’re climbing ladders or working in tight spaces and want a 0.2 kg palm-sized meter
- You troubleshoot frequency or duty cycle on motors and drives
โ Who Should Skip All of These?
If you need to measure high amperage circuits over 10 amps โ like main feeders or large HVAC compressors โ you’ll want a clamp meter instead. Neither of these multimeters is built for that kind of work.
For most utility workers, I’d point you to the Fluke 113. The True-RMS accuracy and CAT IV 300V rating give you the confidence to handle real-world utility troubleshooting, and that’s worth the extra weight.
Frequently Asked Questions
Which is better for utility work, the Fluke 113 or the Fluke 107?
For utility work, I’d pick the Fluke 113 every time. It has a CAT IV 300V safety rating, which is exactly what you need when working near the service entrance or on utility panels. The Fluke 107 only has CAT III 600V, so it’s not rated for the same level of transient protection that utility environments demand.
Does the Fluke 113 measure AC/DC current like the Fluke 107?
No, that’s the biggest difference between them. The Fluke 113 does not measure current at all โ it’s strictly voltage, resistance, and capacitance. The Fluke 107 measures AC and DC current up to 10 amps, so if you need amp readings without a separate clamp meter, the 107 is your only choice here.
Is the Fluke 113 True-RMS worth the extra money over the Fluke 107?
Absolutely, if you work with nonlinear loads like variable frequency drives, LED lighting, or switching power supplies. The Fluke 113 gives you True-RMS accuracy on those waveforms, while the Fluke 107 uses average-sensing and can give you readings that are off by 30% or more on distorted signals. For pure sine wave work, the 107 is fine.
Which multimeter is more portable for field work?
The Fluke 107 is way more portable. It weighs just 0.2 kilograms compared to the 113’s 0.4 kilograms, and it’s designed to fit in the palm of your hand. The 107 also comes with a magnetic lanyard that sticks to metal panels, which is a huge bonus when you’re working on a ladder. If weight and size matter most, the 107 wins hands down.
Can the Fluke 107 measure capacitance like the Fluke 113?
Yes, both meters measure capacitance. But the Fluke 113 goes up to 9,999 microfarads, which covers larger motor start and run capacitors. The Fluke 107 measures capacitance too, but its range is more limited โ I’d trust the 113 for bigger capacitor testing on HVAC and industrial equipment.
Which Fluke multimeter has better battery life?
The Fluke 113 lasts about 300 hours without the backlight, and it has a sleep mode to save power. The Fluke 107 runs on two AAA alkaline batteries, but Fluke doesn’t publish a specific battery life number for it. In my experience, the 113’s 9V battery goes longer between changes because of that sleep mode.
My Final Verdict
The Fluke 113 is my clear winner for utility work because it combines True-RMS accuracy with a CAT IV 300V safety rating โ that’s the protection and precision you need when troubleshooting near the service entrance. The Fluke 107 is a great runner-up if you need to measure AC/DC current up to 10 amps and want something ultra-portable at 0.2 kg, but it can’t match the 113’s safety rating or nonlinear load accuracy.
If you’re on the fence, ask yourself this: are you working near utility panels with distorted waveforms? Then the Fluke 113’s True-RMS and CAT IV rating are non-negotiable. If you’re mostly doing light commercial work and need to check amps, the 107 will serve you well.
