Digitaalne liinitester OOM-4

Digitaalne liinitester OOM-4

Line tester OOM-4 is designed for safe testing of electric detonators lines or its sections, single electric detonators and the connecting cables.

The hermetic, spark-proof design of the line tester housing allows the device to be used in gas explosion-hazardous mines.

A low fixed measurement current (approx. 1mA) is used for measuring.
