Description
Most useful for industrial and service work
Sonel CMM-40 is an instrument with extended measuring capabilities designed for industrial, service and other works. It is used for measuring voltage and current (DC and AC TRUE RMS), capacitance, frequency, duty cycle (power cycle), continuity of connections, resistance and temperature, among other things. Additional functions such as automatic or manual range change, HOLD function, peak hold function and REL function further expand the possibilities of this device.
With its clever ergonomic design and neat dimensions, the CMM-40 is extremely convenient to use and works well even in hard-to-reach places. The easy-to-read backlit display allows you to read the result even in low light. The compact and cost-effective device offers a wide range of measurement capabilities, making it an essential tool for specialists in the field of electrical engineering and sanitary engineering. The Sonel CMM-40 is an instrument which combines a wide range of functions with ease of use and a favourable price, so it can be successfully recommended even to beginners.
