600A AC Load Current Meter and Multifunctional Testing and Distorted Waveforms

Hioki clamp meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The 3281 is a True RMS clamp meter measuring up to 600A load currents, and are housed in a rugged body for long use.

Key Features
Measure current up to 600A
Multi-functional testing of AC current, voltage, frequency, resistance and wave peak value
Non-fuse type protects up to 600 V AC

Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)
Note: The 3281 includes a temperature measurement function, but because the optional Thermister Temperature Probe 9462 has been discontinued, the function is not available for new customers.
