Fluke Clamp Meters Buying Guide
Regarded by industry experts and trade professionals to be the ultimate manufacturer of investigative equipment, this US company is renowned for its robust, reliable, accurate, and long-warranty machines.
Its clamp meter catalog caters to a wide spectrum of meter users — including serious amateurs, light commercial, high-energy contractors, and HVACR engineers. Meaning there’s a unit for every electrical applicational and frequency of operation.
The Fluke Brand
He was shocked at the frequent malfunction of electrical-powered machines at his workplace — typically not due to mechanical failure, but because of incorrect or unreliable voltages, current, and resistance.
As a ‘can-do’ type of guy — he spent all his free time developing and building unique measuring, testing, and analysis tools in order to address the problems. However, his employer, General Electric, considered these inventions nothing more than a novelty and had no interest in pursuing them as a business opportunity.
Hence, in 1948, John Fluke took the initiative and founded the John Fluke Manufacturing Company, Inc — later to become the Fluke Corporation.
Over the following years, Fluke grew into the world’s most respected brand of electrical testing equipment. Today, with over 2500 employees, it has an annual turnover in excess of $851 million — and is run from its headquarters in Everett, Washington, USA.
The Fluke Clamp Meter Range
Make no mistake, Fluke clamping meters are primarily designed for the trade market.
They’re built to withstand the knocks and bumps concomitant to commercial work, typically feature testing capabilities that are contractor project-specific, and retail at premium price points.
That said, if you’re a serious amateur electrician, Fluke does cater to your more basic requirements with the Fluke 323 model. As you progress up the specification ladder, the brand delivers more specialized testing tools — such as the confined space 365, the large component testing Fluke 376, and the HVACR focused 902 model.
What to Look For In Your Fluke Digital Clamp Meter
Your perfect clamp meter has to meet the demands of your projects and your personal preferences. This is particularly crucial when opting for a unit from the premium-priced Fluke machine range, as incorrectly choosing a tool that’s over-specced may excessively hurt your pocket.
For an in-depth guide of clamp meter functions, capabilities, and whether you need them for your job types — take a look at my informative Clamp Meter Buying Guide. However, for considerations that are crucial in Fluke testers, think about the following:
- CAT Safety Certification — indicating the environments suitable for use.
- Head type — fixed clamp, removable clamp, or flexible cable.
- Temperature testing — crucial for HVAC, automotives, and CPU work.
- Auto-ranging — saving the hassle of adjusting dials.
- Microamps — necessary for flame sensor diode investigation.
- Inrush current — for checking start-up motor amperages.
- Low-pass filter — if you deal with VFD motors.
- Low-impedance — shielding against stray and ghost voltages.

Incorporating a unique flexible current probe, the 376 from Fluke delivers a novel take on circuit testing.
A patented iFlex cable — detachable if required — allows you to encircle oddly-shaped components and large wiring looms, offering more versatility than a standard clamp jaw. And, focusing on the trade pro-market, it boasts job-specific capabilities such as VFD (variable frequency drive) investigative motor testing, and inrush current detection.
Rated for CAT III and IV scenarios, it’s suitable for high energy industrial loads, while TRMS tech guarantees analysis accuracy. Its backlit LCD screen promises effortless operation in poorly lit locations, and auto-ranging means you don’t have to manually adjust metrics mid-project.
- Unique current testing flexible probe.
- Low pass filter.
- Detects inrush current.
- Accurate TRMS tech.
- Time-saving auto-ranging.
- No temperature testing facility.
- Some features will be redundant for DIYers and general electricians.
Targeting the residential and commercial market — the high-end Fluke 325 offers reassuring durability combined with electrical testing versatility.
Its temperature testing capability — investigating heat levels from 14 degrees to 752 degrees Fahrenheit — makes the clamper suited to automotive and light HVAC applications. Furthermore, with memory hold and MIN/MAX settings, you can store your readouts for later analysis.
Rated up to CAT IV, safety is assured when using on high-energy utility mains systems. And, its lightweight design in conjunction with an included padded carry case makes the machine ideal for portable use.
- Backlit LCD screen.
- Arrives with batteries.
- CAT III and IV certification.

Stripped back to the essentials of a clamp meter, the 323 from Fluke is a suitable unit for the light commercial user and amateur electrical enthusiast.
Although the premium price point could prove off-putting for casual DIYers, the impressive CAT IV certification should appeal to lay users tackling high-energy projects. It boasts the expected capabilities of resistance, voltage, continuity, and current testing — although it has no temperature, capacitance, or frequency settings.
The machine’s slimline design means it can effortlessly access confined space locations, while TRMS offers welcome precision. What’s more, a generously-sized easy turn selector dial promises thumb operation — ideal for one-handed use.
- Memory hold.
- Durable construction.
- Two-year warranty.
- CAT IV rated.
- A premium-priced basic unit.
- No heat level investigative properties.

Boasting an almost unique removable clamping jaw, the Fluke 365 offers a novel method of circuitry testing.
Permitting you to remove the clamper head and locate around wiring and cables — you can access areas that are inaccessible by a typical meter. And, with a bright backlit LCD screen and in-built flashlight — it’s ideal for environments where illumination is less than ideal.
The machine is suitable for three-phase systems with its CAT III certification, while auto-ranging and TRMS technology mean accuracy without having to switch dials or press buttons. A memory hold system enables you to store your latest data for post-project scrutinization, and straightforward operation suggests it might appeal to newbie clamp meter users.
- Removable clamp jaw.
- CAT III rating for 600 volts.
- Built-in torch.

With over 70 years of experience in electrical scrutiny, they’re the go-to brand for trade professionals and hardcore amateurs that demand the ultimate in precision, versatility, and durability.
When choosing your perfect unit, think about the environments in which your tool will be operated. High-energy operatives should go for CAT IV certification, while those who deal with nothing greater than industrial-level three-phase systems must consider a CAT III rating.
Non-professionals would benefit from a more basic stripped-back machine, and HVAC engineers need a tool capable of temperature testing and flame-investigative microamps. And, for users who need that little bit extra, they should think about wireless tech or a removable or flexible clamp head.
Admittedly, for some DIYers and light contractors, the price-points may be a barrier. But, for guys who want nothing less than the best — there are few units that equal Fluke clamp meters.
