Ermenrich Zing WT40 Voltage Tester

The Ermenrich Zing WT40 Voltage Tester is a portable device with simple operation that can be used to detect the presence of the AC voltage in a wire or socket. As a result, the tester can quickly find a broken wire or detect faults in the electrical system in your house or apartment. You can use it for professional purposes and home maintenance.

It is a non-contact voltage tester. The device can check either low (12–48V) or high (48–1000V) AC voltage and gives different signals when detected. The beep will vary in pitch, and the lights will either be flashing or constantly on.

The device also has a built-in flashlight. If the flashlight does not turn on or its light is dim, it means that the batteries should be replaced immediately.

Key features:

• Non-contact AC voltage testing


• Different light and sound signals of the two measured voltage ranges


• Powered by batteries, built-in flashlight
