Clamp meters, engineered for the most demanding conditions

New design increases flexibility, safety and performance

Fluke has introduced the industry’s most advanced, capable and reliable family of clamp meters, designed to meet the unique requirements of users testing and maintaining electrical systems, industrial equipment and controls, and commercial and industrial HVAC equipment.

This new family of rugged, easy-to-use clamp meters includes the Fluke 373/4/5/6 and 381, providing a range of state-of-the-art capabilities to meet users’ most demanding requirements for flexibility, safety and performance. New Fluke iFlex™ flexible current probes expand the measurement range of the Fluke 374, 375, 376 and 381 meters to 2500A AC while providing the ultimate measurement flexibility. Every clamp meter in the family is improved: they feature thinner, smaller jaws for easier use in crowded equipment cabinets, large backlit displays, true-rms standard, increased resistance range and overmoulding for easier handling and improved survival if dropped.
The new Fluke family of clamp meters
The new family enables electricians to perform all of the measurements needed, without having to reach for another tool. It includes:

Fluke 381 Remote Display True-rms AC/DC Clamp Meter with iFlex - the Fluke 381 is a full-featured clamp meter with an important extra: users can remove the detachable wireless display for even more flexibility, convenience and safety. Now one technician can do jobs that used to require two: clamp the Fluke 381 around a conductor, remove the display, then close the equipment cabinet or move across the room to operate controls, all while watching real-time readings. It includes the new iFlex flexible current probe (see below).

Fluke 376 True-rms AC/DC Clamp Meter with iFlex - with the new Fluke 376 Clamp Meter, users will be ready for any measurement challenge. Designed for the toughest industrial environments, it measures current up to 2500A AC and 1000A DC and can troubleshoot even the noisiest motors and drives. With true-rms AC voltage and current measurements, min/max/average and inrush recording, the Fluke 376 can read up to 1000V and 1000A in both AC and DC modes. The Fluke 376 includes the new iFlex flexible current probe. The Fluke 376 is the direct replacement for the Fluke 337.
Fluke 374 and 375 True-rms AC/DC Clamp Meters - the new Fluke 374 and 375 clamp meters offer improved performance, perfect for many current measurement situations. With true-rms AC voltage and current measurements, the Fluke 374 and 375 can read up to 600V and 600A in both AC and DC modes and handle min/max, average and inrush recording. Both are compatible with the new iFlex™ flexible current probe (sold separately). Ideal in an industrial environment, the Fluke 375 has an integrated low pass noise filter and measures frequency to 500Hz and mV DC for use with a wide range of accessories.

Fluke 373 True-rms AC Clamp Meter - the new Fluke 373 clamp meter offers improved performance and maximum value for users requiring AC only current measurement.. With true-rms AC voltage and current measurements, the Fluke 373 reads up to 600A AC and 600V AC or DC.

iFlex i2500-18 and i2500-10 Flexible Current Probes - the new Fluke iFlex flexible current probes expand the measurement range of the select Fluke meters to 2500A AC while providing the ultimate measurement flexibility. The iFlex probes connect directly to the meter, displaying current measurements without error prone scaling factors. The large coil allows users to reach around large or awkward-shaped conductors, while the small 7.5mm profile allows the coil to reach between tightly-packed cables and improves access in crowded spaces. A 2m lead makes it easier to see readings at a distance from the conductor. Available in 25cm and 45cm sizes. Included with the Fluke 381 and Fluke 376 Clamp Meters; compatible with Fluke 374 and Fluke 375 Clamp Meters.

Safety ratings too are improved. The Fluke 381, 376, 375, 374 and iFlex current probes are rated for safe use in hazard category IV (CAT IV) 600V environments (CAT IV 600V, CAT III 1000V) as defined by safety regulators in the US, Canada and Europe. The Fluke 373 is rated CAT IV 300V, CAT III 600V. A CAT IV safety rating is required for use in outdoor environments.
