Hioki-3290 Clamp on AC/DC HiTester

Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The 3290 and 3290-10 feature detachable clamp sensors to offer a maximum 2000A current range.

·         Choose from three sensors

·         Correctly measure for inverter current with AC+DC mode and True RMS rectification

·         Choice of output (Simultaneous output): Effective value, waveform, frequency, and integral value output

·         Choice of response time with three steps

·         Model 3290-10 supports current integration and operating ratio measurements
