The Ermenrich Zing WT30 is a small measuring and diagnostic tool for handymen and professional electricians. The voltage is measured using touch technology: the probe must come into contact with the live conductor. At the same time, the device can detect the high voltage zone without contact. In NCV mode, you can search for hidden wires, as well as find possible breaks and live wires. With the voltage tester, the integrity of the conductor disconnected from the power source can be checked, as well as the polarity of the element can be determined.

The device notifies the user of the measurement results with sound and light signals of various intensities. Additional information can be seen on the built-in screen. The display is backlit. The device has a built-in flashlight. All this makes it easier to work in low light conditions or in total darkness. Power supply: a standard item. It also has an automatic shut-off function. When the battery needs to be replaced, a notification icon will appear on the screen.
