Fluke Clamp Meters Buying Guide

If you demand an electrical circuit tester that hails from a premium brand — consider the Fluke clamp meters range.

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

In 1945, fresh out of the US Navy after the end of World War II, Commander John Fluke joined General Electric — his service-gained knowledge of electrical systems and circuitry made this new position a natural progression of his career. However, during the first two years of his employment, he became somewhat disgruntled.

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.

Conclusion


Fluke Multi Clamp Meters are the pinnacle of handheld circuit testing.

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.
