probe type induction, plastic insulation, It will flash and beep when the device close to AC Voltage greater during the specified Voltage range without touching the measured object, to ensure the safety of the human body, more convenient monitoring.

Distinguish the live and Null wire through different frequency alarm sounds. The higher the voltage, the higher the audible alarm frequency and rate of flashing lights - great, even in noisy environments.

Accurately detects AC Voltage ranging from 12V to 1000V, and distinguishes them into 3 Voltage levels (low, moderate, high). ncv sensitivity automatically adjusts from low, medium and high while indicating Voltage level with audible beep.
