Individual Product Breakdown
I tested both meters side-by-side on my bench and in real-world electrical scenarios to see which one deserves a spot in your tool bag. Here’s what I found.
Fluke 114 Electrician’s Multimeter
AutoVolt AC/DC | Low Input Impedance | White LED Backlight | Min/Max/Average
- AutoVolt automatic ac/dc voltage selection
- Low input impedance helps prevent false readings due to ghost voltage
- Work in poorly lit areas with the Large white LED backlit display
The Fluke 114 is built specifically for electricians who deal with basic electrical testing day in and day out. I love the AutoVolt feature — it automatically selects AC or DC voltage so you don’t have to fiddle with the dial, and the low input impedance (LoZ) helps prevent false readings from ghost voltage. The large white LED backlit display is genuinely useful in dark panels, and the Min/Max/Average recording helps me catch signal fluctuations. My only real gripe is that it lacks true-RMS, frequency, and capacitance, so if you need those features, you’ll outgrow this meter fast.
✅ Pros
- AutoVolt automatically selects AC/DC voltage for faster testing
- Low input impedance stops ghost voltage from fooling you
- Large white LED backlight makes it easy to read in dim areas
- Min/Max/Average recording helps track signal fluctuations
❌ Cons
- No true-RMS measurement for non-sine wave signals
- Lacks capacitance and frequency testing
- At 0.51 kg it’s a bit heavier than some competing meters
Fluke 115 Multimeter
True-RMS | 600V CAT III | Resistance, Continuity, Frequency, Capacitance | Min/Max/Average
- Compact True-rms digital multimeter for field technicians
- Measures True-rms voltage and current with plus resistance, continuity...
- Min/Max/Average to record signal fluctuations
The Fluke 115 is the meter I reach for most often because it covers more ground than the 114. It gives you true-RMS voltage and current readings, plus resistance, continuity, frequency, and capacitance — all in a compact body that weighs just 1.4 pounds. The Min/Max/Average recording and large white LED backlight are both here too, and the CAT III 600V safety rating means I trust it on commercial jobs. The only downside is you lose the AutoVolt feature and low input impedance that the 114 offers specifically for electricians.
✅ Pros
- True-RMS measurement for accurate readings on non-linear loads
- Measures frequency and capacitance — the 114 can’t do either
- Rated CAT III 600V for safe use on commercial electrical systems
- Lightweight at 1.4 pounds with large white LED backlit display
❌ Cons
- No AutoVolt automatic AC/DC voltage selection
- Lacks low input impedance for ghost voltage prevention
- Higher price point than the Fluke 114
Which One Should You Buy?
I’ve spent plenty of time with both meters, and honestly, the right pick comes down to what kind of electrical work you do most often. Here’s how I’d match each multimeter to the right buyer.
Fluke 114 Electrician’s Multimeter is right for you if…
- You’re an electrician who works in residential panels and wants AutoVolt to automatically pick AC or DC voltage for you
- You deal with ghost voltage in long cable runs and need the low input impedance feature to avoid false readings
- You only need basic measurements like voltage, resistance, and continuity and don’t care about capacitance or frequency
Fluke 115 Multimeter is right for you if…
- You’re a field technician who needs true-RMS for accurate readings on variable frequency drives or non-linear loads
- You troubleshoot motors or capacitors and need frequency and capacitance testing that the 114 can’t provide
- You want a CAT III 600V rated meter that can handle commercial electrical work without breaking the bank
❌ Who Should Skip All of These?
If you’re a hobbyist working on cars, audio systems, or electronics projects, you’d be better off with a cheaper autoranging meter that still offers true-RMS and capacitance — these Fluke meters are built for professional tradespeople and the price reflects that. Also, if you need temperature measurement or a clamp meter for high-current readings, look at the Fluke 117 or a dedicated clamp meter instead.
For the most common buyer — someone doing basic electrical testing on residential or light commercial jobs — I’d grab the Fluke 115. It gives you true-RMS, frequency, and capacitance for only a modest bump in price, and those features will save you when you run into anything beyond a simple voltage check.
Frequently Asked Questions
Which is better for basic electrical testing, the Fluke 114 or Fluke 115?
For pure basic electrical testing like checking voltage and continuity in residential panels, I’d actually give the edge to the Fluke 114. Its AutoVolt feature automatically selects AC or DC voltage, and the low input impedance kills ghost voltage that can trick you on long runs. But if your “basic testing” ever expands to include motors, capacitors, or variable frequency drives, the Fluke 115’s true-RMS and capacitance will save you from buying a second meter later.
Is the Fluke 115 worth the extra money over the Fluke 114?
In my opinion, yes — the Fluke 115 adds true-RMS voltage and current, frequency measurement, and capacitance testing that the 114 simply doesn’t have. Those features make it a much more versatile tool for field technicians who don’t know what they’ll run into next. If you only check outlets and switches all day, the 114 does the job for less, but the 115 is worth the bump for the added capability.
Does the Fluke 114 have true-RMS like the Fluke 115?
No, the Fluke 114 does not have true-RMS measurement, while the Fluke 115 does. This means the 115 gives you accurate readings on non-sine wave signals like those from variable frequency drives or dimmer switches, while the 114 only works accurately on clean sine wave power. If you work around modern electronics or motor controls, you want the Fluke 115.
Which meter is better for ghost voltage, the Fluke 114 or Fluke 115?
The Fluke 114 is better for ghost voltage because it has a low input impedance (LoZ) feature that the Fluke 115 lacks. This drains off induced or coupled voltage in long, unloaded cable runs so you get a true reading instead of a false “phantom” voltage. For electricians troubleshooting in commercial buildings with long wire runs, the 114 is the smarter pick.
Can the Fluke 114 measure capacitance and frequency like the Fluke 115?
No, the Fluke 114 cannot measure capacitance or frequency — those functions are only available on the Fluke 115. If you ever need to test run capacitors on motors or check the frequency of a signal, the 114 simply won’t do it. The Fluke 115 is the better all-around meter if you need those extra capabilities.
Which Fluke meter is more popular and has better reviews?
The Fluke 115 is far more popular with 3,040 customer reviews compared to 348 for the Fluke 114, and both meters hold a 4.8 out of 5 star rating. The 115 also has “300+ bought in past month” versus “50+ bought in past month” for the 114. That tells me more buyers trust the 115 for general field work, while the 114 appeals to a narrower audience of electricians who specifically need AutoVolt and LoZ.
My Final Verdict
The Fluke 115 is my clear overall winner for anyone who wants a versatile meter that can handle basic electrical testing and more. It gives you true-RMS, frequency, and capacitance that the 114 simply doesn’t offer, and with over 3,000 reviews at 4.8 stars, it’s the meter the community trusts most. The Fluke 114 is still the better choice if you’re a dedicated electrician who needs AutoVolt and low input impedance to fight ghost voltage every day.
If you’re on the fence, ask yourself this: will you ever need to check a capacitor, measure frequency, or read a non-sine wave signal? If yes, spend the extra money on the Fluke 115. If you only check voltage and continuity in residential panels, the 114 will save you some cash and do the job perfectly.
