Benefits of the Yokogawa CL Series Handheld Devices in Clampmeter Design

Combination of current clamp and measurement instrument with display.
Measurement of AC current, AC/DC current, and leakage current.
Wide clamp opening for conductors up to 54 mm in diameter.

Yokogawa CL Series Clamp-On Testers

Yokogawa CL series are handy, light weight and compact clamp-on testers. Models are available for AC current measurement, AC/DC current measurement and leakage current measurements, with various current ranges and diameters. Depending on the model they have a mean value or true RMS display. All models have a data old function.
