The Hioki CM3281 is an average rectified 2000A AC clamp meter that features a broad operating temperature range, thin and compact clamp core, and optional flexible current sensor (sold separately) that can get into the tightest spots.

The CM3281 features large jaws that let you clamp with ease, while its innovative design lets you get between narrow cable gaps, improving work efficiency at the worksite. The compact meter delivers a wide measurement range from a few amperes up to 2000 A.

The CM2381 has the ability to measure up to 2000A AC using the mean rectification method. The meter uses the mean rectification method to generate indicated values that approach the fundamental wave component. In addition to current measurement, the CM3281 delivers voltage measurement, continuity check, and resistance measurement functionality.

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