Pocket-sized multimeter with tough nature
Simple and compact digital multimeter Sonel CMM-11 surprises with its lightning fast operation and measurement precision. The device is most frequently used for quick diagnostics of electrical equipment and circuits. Its handy design makes it easy to fit in any tool bag and it does not take up much space. It has all the basic measuring functions, and due to its rubberised casing, it is not affected by drops and mechanical damage. It is ideal for every electrician, fitter and maintenance technician, as well as others in the electrical and power industry. It performs well even under difficult operating conditions and, due to its backlit display, it enables easy reading of the measurement result even in poor lighting conditions.
Extremely durable and robust
In response to the needs of our customers, we have made the CMM-11 device resistant to accidental impacts that can lead to unit damage. The elastomer material used in the housing protects the unit if it is dropped and absorbs the shocks caused by such impacts.
Protection against dust penetration and streams of water
The housing has been designed for use in the field. The IP65 degree provides protection the unit against dust penetration and accidental flooding with a stream of water.
Compact housing
Limited space in your tool box? It is not a problem with CMM-11. Thanks to the small dimensions, the unit even fits in your pocket.
Good visibility in any conditions
Insufficient lighting where the measurements are being taken is not an obstacle anymore thanks to the integrated flashlight.
Wireless communication
The device can wirelessly send the results of measurements ("live" mode) to the mobile application – Sonel Multimeter Mobile. It enables the recording and storage of results, notes and photos can be added or files attached to e-mail messages later on.
