Screwdriver Tester, AC Voltage Tester Pen 12-300V, Voltage Detector, Live/Neutral Wire Tester, with Display, Flashlight, Audible Alarm

General Description

The voltage tester screwdriver is an essential tool for measuring AC voltage from 12 to 300V. It is equipped with an LCD screen that displays the voltage value during contact measurement.

In induction mode, it detects voltage without contact and emits a beep whose frequency increases with the voltage.

This device is also capable of performing continuity and battery polarity tests.

Technical Specifications

Measured Voltage: 12 to 300V
