The CM Series range of professional clamp meters from Martindale Electric, makes 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 equipment gets the job done.

The pocket-sized clamp range includes the CM55 AC Clamp, CM57 TRMS AC Smart Clamp and the CM79 TRMS AC/DC Clamp, combining outstanding specification and measuring capabilities with reliability and ease of use.

The clamp meters meet the exacting requirements of electricians and service teams 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 compact design also enables accurate and reliable current measurement down to 10mA resolution without the need to break into the circuit.

Following on from the CM55, is the CM57 TRMS Smart Clamp Multimeter which measures AC current up to 600A, AC/DC voltage, resistance with continuity test plus capacitance, frequency and diode test making it well suited to HVAC applications.

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. The professional clamp is ideal for applications involving PV installations, battery monitoring, UPS systems and electric vehicles.
