Null Wire Tester, Home Circuit Tester, Portable Induction Pen Voltage Detector, PE Voltage Tester for Home Electrician

1. A tester that can measure three-phase electricity, detect phase sequence without contact, divided into three modes: left-handed/right-handed/disordered. 2. Provides a zero-line and firing test, an audible and visual alarm, results are clear at a glance, and includes a high/low sensitivity switch. 3. Supports circuit break point detection, safe power supply verification, and clear circuit distribution. 4. Long press the function button to turn on the flashlight, allowing for worry-free measurement in dark environments. 5. After approximately 5 minutes of inactivity, the tester will automatically turn off. When the battery voltage is low, the screen displays a reminder symbol.
