EARTH RESISTANCE TESTER TESTBOY TV441

The earth resistance measuring device Testboy TV 441 is used to check the resistance between the reference earth and the connection point of the earthing system. For the measurement, an alternating current is supplied between an auxiliary earth electrode and the earth electrode to be measured. Using a probe located within the reference earth range of the earth electrode to be measured, the voltage drop is measured and the earthing resistance is determined (three-wire method). The kit includes earthing spikes, a set of measuring lines and a bag.

Advantages:

Automatic shutdown
Measurement memory for 100 measured values
