Non-contact, automatic voltage testing for voltages from 12 to 1000 V AC for a wide range of applications. Designed for non-contact testing of AC voltages. Displays 12 to 1000 V AC with simultaneous visual and acoustic voltage indication. The bright flashlight for illuminating the work area can be used independently of the voltage tester. The visual LED bar graph indicates the present voltage - the higher the detected voltage or the closer the voltage source, the more LEDs light up. Voltage indication with a bar graph of five glowing LEDs for easy interpretation and reading. The acoustic voltage detector beeps at a higher frequency as the voltage increases or as the device gets closer to a voltage source. Automatic shut-off conserves battery life and extends battery longevity. The screw-on battery cap with O-ring prevents dust and water ingress. Lightweight, compact tool with pocket clip for easy storage and quick access. IP67: Dustproof and waterproof. Drop protection up to 2 m. Protection rating CAT IV for 1000 V.
