Fluke 374 FC vs 375 FC vs 376 FC vs 902 FC (2026): Which Clamp Meter?

Why you should trust this comparison

I built this comparison from Fluke’s published datasheets and the documented feature sets for each model, not from an invented bench test. I have not personally measured these four meters side by side, so every number you see here is attributed to the manufacturer’s spec sheet or to the Amazon feature snippets supplied for each tool. Where Fluke lists a hard figure I cite it; where I am not certain of an exact value, I say so plainly and use a qualitative description instead of guessing a precise number.

That approach matters with a lineup like this because the four meters look almost identical and share the same Fluke Connect ecosystem, yet they are aimed at very different jobs. The 374, 375 and 376 FC are general-purpose AC/DC clamp meters that climb in capability, while the 902 FC is a dedicated HVAC clamp meter that happens to share the same wireless platform. Reading the spec sheets carefully is the only honest way to separate them, so that is what this guide does.

How we compared them

I focused on the criteria that actually decide which clamp meter belongs in your bag: current measurement type and range, whether DC current is supported, true-RMS accuracy on non-linear loads, the bandwidth and resolution Fluke documents, wireless and logging features, and the safety rating. I also weighed which trade each meter is built for, because a combustion-focused meter and a motor-shop meter are not interchangeable even when they share a body.

I leaned hardest on capability differences that Fluke documents clearly, such as the 376 FC’s onboard logging and trending and the 902 FC’s microamp flame-rod range, since those are the features that genuinely change what you can do on a job. I avoided ranking on small accuracy deltas that I cannot verify firsthand, and I flagged one honest limitation for each model so you know the trade-off before you commit.

How they compare at a glance

Fluke 374 FC

The Fluke 374 FC is the entry point into Fluke’s wireless 370-series clamp meters. Fluke describes it as a true-RMS meter that reads 600 A AC and DC current, expandable to 2500 A AC with the optional iFlex flexible probe, and it pairs with the Fluke Connect app so you can read measurements on your phone at a safer distance while wearing less PPE. Results record straight to your phone and the cloud, which is the headline reason to step into this family rather than a standard non-wireless clamp.

It suits a technician who wants Fluke build quality, true-RMS accuracy on non-linear signals, and wireless logging to a phone without paying for the higher models. If your daily work is general motor, panel and HVAC current checks where DC current and 600 A coverage are enough, the 374 FC covers it.

The honest limitation is that the 374 FC sits at the bottom of the range, so its true-RMS measurement range and feature depth are narrower than the 375 FC. If you regularly need the widest range Fluke offers in this body or expect to grow into more demanding work, the small saving over the 375 FC can be a false economy.

Fluke 375 FC

The Fluke 375 FC is the model I would point most electricians toward. It shares the 374 FC’s core, with the same Fluke Connect wireless capture, 600 A AC and DC current, and 2500 A AC expansion using the optional iFlex probe, but Fluke positions it a step above the 374 with a wider true-RMS measurement envelope. For everyday electrical work that mix of AC and DC current plus wireless logging hits the sweet spot.

It is the natural pick for a working electrician or maintenance tech who wants one clamp that handles motors, drives and general panels without thinking about whether the range will run out. The Fluke Connect integration means you can stand clear of the arc-flash zone and still log results, which is a genuine safety benefit Fluke emphasizes across this line.

The honest limitation is that the 375 FC does not log and trend measurements onboard the way the 376 FC does. If you are chasing intermittent faults that only appear over hours, the 375 FC will not capture that history for you, and you would need to step up to the 376 FC.

Fluke 376 FC

The Fluke 376 FC is the top general-purpose model in this group, and its defining feature is logging and trending. Fluke documents that it can log and trend measurements to pinpoint intermittent faults, capture readings outside the arc-flash zone with Bluetooth to your Apple or Android device, and transmit results wirelessly through the Fluke Connect app. It also commonly ships with the iFlex flexible probe, so the 2500 A AC expansion is in the box rather than an add-on.

This meter is for the technician whose hardest problems are intermittent: a breaker that trips occasionally, a motor that draws odd current only under load, or a circuit that misbehaves overnight. The ability to record a trend and review it later is the single biggest reason to choose the 376 FC over the 375 FC, and the bundled iFlex adds flexibility for awkward, large or tightly packed conductors.

The honest limitation is cost and complexity. For a tech who never needs trending, the logging capability is capability you pay for and rarely use, and the 375 FC would do the same daily measurements for less outlay.

Fluke 902 FC

The Fluke 902 FC is the odd one out, and deliberately so: it is a true-RMS HVAC clamp meter rather than a general electrical instrument. Fluke designed it for combustion and refrigeration work, with 200 microamp DC current measurement to check a flame rod, an extended resistance range to read thermistors up to 60 kiloohms, and the ability to capture flue-gas temperature. Like the rest of the lineup it connects to your phone through Fluke Connect over Bluetooth, and it offers true-RMS voltage and current for accurate readings on non-linear signals.

It suits HVAC and refrigeration technicians who need those combustion-specific functions in one clamp. The microamp flame-rod range and thermistor measurement are tasks a general clamp meter simply cannot do, so for that trade the 902 FC is the right tool in this family.

The honest limitation is that the 902 FC is specialized. If your work is general electrical rather than HVAC, you would be buying ranges tuned for combustion diagnostics and giving up the broader general-purpose strengths of the 375 or 376 FC. Match it to the trade, not to the badge.

Which should you buy?

If you are a general electrician who wants one do-everything wireless clamp, buy the Fluke 375 FC. It gives you AC and DC current, true-RMS accuracy and Fluke Connect logging without the premium of the top model. If you are price-sensitive and your work stays within the entry range, the Fluke 374 FC is the same platform for a bit less, with a slightly narrower spec.

If your job involves intermittent faults that only logging can catch, step up to the Fluke 376 FC for its onboard trending and the bundled iFlex probe. And if you are an HVAC or combustion tech, the Fluke 902 FC is the only one of the four built for flame-rod, thermistor and flue-gas work, so buy it for that purpose and nothing else.

Frequently asked questions

What is the difference between the Fluke 374 FC and 375 FC? Both are wireless true-RMS AC/DC clamp meters reading 600 A and expandable to 2500 A AC with iFlex. Fluke positions the 375 FC a step above with a wider measurement range, so most electricians prefer it; the 374 FC is the slightly more basic, lower-cost entry.

Do I need the Fluke 376 FC over the 375 FC? Only if you need to log and trend measurements to catch intermittent faults. Fluke gives the 376 FC onboard logging and typically bundles the iFlex probe. For straightforward daily readings the 375 FC is enough.

Can the Fluke 902 FC be used for general electrical work? It is built as an HVAC clamp meter for flame rod, thermistor and flue-gas measurements, so it is not the best choice for general electrical jobs. For panels and motors, choose the 374, 375 or 376 FC instead.

The verdict

Across this lineup the Fluke 375 FC is the meter most buyers should choose: it pairs true-RMS AC and DC current with Fluke Connect wireless logging at a sensible step above the entry 374 FC. Move up to the 376 FC when intermittent faults demand onboard logging and trending, drop to the 374 FC if budget rules and the narrower spec is fine, and reserve the 902 FC for HVAC and combustion work where its flame-rod and flue-gas functions are exactly what the job needs. Match the meter to the trade and any of these four will serve you well.
