CM3281 - AC Current clamp meter, 2000 A

Product information CM3281 - AC Current clamp meter, 2000 A

The 3288-20 AC/DC Clamp Multimeter is a compact, multi-functional clamp meter designed for quick and efficient equipment diagnostics. It measures AC/DC current and voltage, while also offering resistance, continuity, and crest factor checks. With a slim profile and double jaw lever, it’s ideal for accessing crowded wires in industrial environments. The True RMS functionality ensures precise measurements, even for distorted waveforms, making it perfect for high-current applications such as UPS emergency batteries and train motors.
