Simplify Your Harmonic Analysis

By coupling the Hioki CM4371-50 with our free GENNECT Cross app, you can perform simple harmonic analysis, which is crucial for problem analysis of power supply systems.

Experience Convenience in Repeated Measurements

The automatic hold function of this clamp meter ensures convenience during repeated measurement and recording tasks. When the measurement value stabilises, it is automatically held until the next measurement.

Assess transient currents at motor startup

Hioki CM4371-50 clamp meters are capable of measuring both RMS inrush current and maximum crest values during motor startup and welding currents. These meters automatically detect the duration of the inrush current, which can range from several dozen milliseconds to several hundred milliseconds, resulting in more accurate measurements compared to standard clamp-on meters with a fixed 100 ms measurement interval. Invest in our clamp meters for reliable and precise measurements in various applications.

Enjoy More Features with Hioki CM4371-50

The Hioki CM4371-50 is also equipped with Test Lead L9300 that incorporates integrated caps for greater safety. This design lets you change the measurement category by merely sliding the test lead’s protective finger guard.
