Motwane DCM39A

 

MOTWANE’s Digital Clamp Meter DCM 39A & DCM 9930A comprises high precision, industrial grade, RMS, auto-ranging clamp meters with 3¾ digits display. Both the clamp meters can be used as multimeters with test leads for AC/DC measurements of up to 400 mA, along with measuring AC/DC voltage, resistance, frequency, capacitance, duty cycle, diode, continuity, etc. These clamp meters are provided with multiple safety features like a water-resistant front panel and fireproof heavy-duty ABS casing. It uses the Hall Effect sensor for measuring the current. The model DCM 39A measures AC/DC currents up to 1000A. The model DCM 9930A measures AC/DC currents up to 2000A.
