HIOKI Clamp Meters – Made in Japan since 1971

0_TOP-Category-HIOKI-CM4141-50-true-rms-clamp-multimeter-2000a-ac-low-current

Field-proven in installation, maintenance, and troubleshooting

Clamp meters are used wherever current needs to be measured quickly, safely, and without interrupting the circuit – ideal for troubleshooting, maintenance, and installation. 
Choose the right HIOKI clamp meter from our four main groups: 

  • AC clamp meters – for standard installation measurements 
  • AC/DC clamp meters & clamp multimeters – for DC, voltage, and multi-parameter testing 
  • AC leakage clamp meters – for detecting leakage, differential, and load currents 
  • AC clamp power meters – for analyzing electrical power, power factor, and phase conditions 

Whether checking load currents, locating leakage, or evaluating power – HIOKI has been manufacturing clamp meters exclusively in its own factories in Japan since 1971.
