Large Jaw Lets You Clamp with Ease

New and innovative design lets you get between narrow cable gaps despite large jaw offering, improving work efficiency at the worksite. The compact meter delivers a wide measurement range from a few amperes up to 2000 A.


A pocket clamp meter that can use flexible sensors

When connected to an optional flexible current sensor*, the CM3281 can be used to measure the current flowing in pairs of wires or in tangled or complexly routed wires around which it was not possible to apply a clamp-on sensor in the past. *AC FLEXIBLE CURRENT SENSOR CT6280 (4200 A AC, Φ130 mm)


Essential for electrical work: A thin card tester that fits in the pocket with all the capabilities of a clamp meter

The CM3281 delivers all the functionality of a clamp meter and card tester in the form factor of the latter. In addition to current measurement, this single instrument delivers voltage measurement, continuity check, and resistance measurement functionality.


Rugged, portable design that’s drop-resistant

Despite its thin, compact design, the CM3281 has an operating temperature range of -25°C to 65°C and can withstand being dropped from a height of 1 m onto concrete. It’s engineered for use in tough environments.
