1. Air detection, non-contact power measurement, and the line skin can be attached to alarm
2. Zero live wire detection, easy to operate and clear display. Generally, when simulating a bright red three-segment signal, the electric pen detects the live wire; when simulating a bright green three-segment signal, the electric pen detects a neutral or ground wire
3. Rapid alarm sound + flashing lights, the analog bar of the display will increase or decrease with the intensity of the sensed voltage signal, and the buzzer sound will also become faster or slower with the signal strength
4. Flashlight lighting, easy to measure in the dark environment, long press the blue button to turn on the flashlight lighting, easy measurement in the dark environment
5. After about 3 minutes of no induction signal or no operation, the tester will automatically shut down. When the battery voltage is low, the tester's sensor light will light up once and then automatically shut down.
6. Humanized pen holder, more convenient to carry around
7. Highly sensitive probe, quick response, more stable measurement
8. Non-contact induction voltage range: 12-1000V
9. Power supply: 2 1.5V AAA batteries (not included)
10. Size: about 8.7x2.3 cm
