New Design Pen Type AC non contact voltage tester NCV detector
- Adjustable sensitivity: Dual range AC 12V- 1000V / 48V- 1000V, choose different ranges according to your needs;
- Different voltage test and dual range test - electric wire and zero line can be distinguished by different frequency of alarm sounds; the default AC voltage measurement range is 48-1000V, and 12-1000V can also be measured by adjusting the sensitivity, to meet the need to select the most suitable sensitivity before testing in different occasions and different objects;
- Non-contact voltage tester - When the device is close to the AC voltage within the specified voltage range, it will emit a LED light and beep sound without touching the object under test to support adequate safety measurement applications;
- LED light & low voltage indicator light - low voltage LED and alarm light prompts can remind you to replace the battery in time, the white LED light can work normally in the dark environment; no automatic operation for 5 minutes to save energy;
- Safe sound and light alarm - Distinguish voltage frequency by buzzer and LED indicator. Its sound is enough to hear the noise of medium machinery;
- Small size, easy to store in the toolbox or carried in your pocket.
