AC voltage tester, automatic shut-off, HD screen, highly sensitive voltage tester (12–1000 V)

1. Cable Testing: A live conductor is quickly alerted by a red light. A neutral conductor is slowly alerted by a green light. Safe and easy to test, with audible and visual alarms and a clear display. 2. Flashlight Function: A bright, integrated flashlight is located at the end of the smart voltage tester, allowing you to work even in dimly lit areas. 3. Automatic Shut-Off: The voltage tester automatically shuts off after 5 minutes of inactivity and no voltage signal. 4. Ambient Temperature Display: The voltage tester measures ambient temperatures from 0 to 70°C and displays the current temperature. It is therefore suitable for complex environments. 5. High Sensitivity: The voltage tester can be switched to high sensitivity, enabling testing for circuit breaks, checking cable safety, and insulation testing. This allows you to determine the wiring layout in your home. 6. User-Friendly Clip: This voltage tester is easy to carry and features a user-friendly clip, making it convenient to take with you at all times.
