The new range of professional clamp meters from Martindale Electric, make it easy to choose the right tool for the job every time. Whether it’s low current AC, or DC for solar PV and battery systems, the CM Series get the job done. The pocket sized range includes the CM55 AC Clamp, CM57 TRMS AC Smart Clamp and the CM79 TRMS AC/DC Clamp.
The new clamps meet the exacting requirements of electricians and those working on both AC and DC systems, from basic AC measurements through to min/max monitoring of start-up and charging currents. All the clamps are auto-ranging and measure current to better than 2% accuracy.
The entry level CM55 is a high performance AC clamp meter which measures AC current up to 400A, AC/DC voltage and resistance with continuity test. The CM57 TRMS Smart Clamp Multimeter measures AC current up to 600A, AC/DC voltage, resistance with continuity test plus capacitance, frequency and diode test, making it suited to HVAC applications.
True RMS measurement ensures accurate and reliable AC current and voltage measurement for distorted waveforms generated by today’s power electronics and non-linear loads.
The CM79 TRMS Clamp meter features AC and DC current measurement up to 600A with Min/Max for monitoring maximum loads, start up and charging currents.
All products come with a two year warranty.
