Description
The CL155 is a versatile and highly accurate Clamp-on meter with a array of features ideal for most applications. The CL155 is the true RMS version of the CL150 series, with the added benefit of being able to provide a better reading representation of waveforms with distortions and harmonics.. This unit is rugged, reliable and cost effective. Jaws accommodate up to 30mm conductors.
