CMM-40 digital multimeter with calibration certificate (voltage) WMGBCMM40

Industrial multimeter, which is a universal device that measures voltage and current (constant and alternating TRUE RMS), and additionally capacity, frequency, duty cycle (filling), continuity of connections, resistance, temperature. The meter is characterized by high resistance to weather conditions and external factors (IP67).

The most important features of the CMM-40 device include:

• Automatic or manual ranging.
• HOLD function for reading measurements in low light or in hard to reach places.
• REL function for relative measurements.
• MAX function/ MIN.
• Peak hold function.
• Beeper for continuity.
• Automatic shutdown when not in use.
• 4¾ display digits (max. 40000).
• Waterproof two-component housing.
