Customer Reviews


The Sanwa DCM660R is a digital clamp-meter with digital multimeter capabilities.

The DCM660R can be used in a CAT III environment and can measure a current of up to 660 Amperes. Since this instrument also has digital multimeter functionalities it can also measure AC+DC voltage, resistance, and frequency as well as perform continuity tests.

The device uses the double integration operation method and True RMS for AC measuring. The display on this device is a large 6600-count LCD display with backlight. The DCM660R has a safety design compliant with the IEC61010-1 standard.

Meter comes with one set of test leads, carrying case and instructions.
