Martindale's CM87 is a dual-current (AC/DC) clamp meter with large-size jaws.

The upgraded version of the Martindale CM82, the CM87 has wider measurement range, giving users the ability to test much more. The large-size, 57mm jaws are suitable for use on everything from smaller to larger conductors and once clamped on, both AC and DC current can be tested.

The CM87 can measure AC current to 1500A, DC current to 2000A and can also measure AC voltage to 750V, DC voltage to 1000V plus testing procedures for resistance, capacitance, frequency, duty cycle, type K thermocouple temperature, continuity and diode.

This clamp meter is perfect for any electrician, plus maintenance and service engineers.
