600A and 1000A AC Load Current Meters and Multifunctional Testing and Distorted Waveforms
Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The 3281 and 3282 are True RMS clamp meters measuring up to 600A and 1000A load currents, and are housed in a rugged body for long use.
• Choose from two models to measure current up to 600A or 1000A
• 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, or opening and closing of the clamp sensor 10,000 times)
