【Visual & Audible Alert】 When voltage is detected, the tip emits a red light, the screen turns red, and a signal sound is triggered. As the detected voltage increases, the red light and the sound frequency accelerates. Meanwhile, the LCD screen's percentage value and bar graphs also increase. It could be applied to test AC voltage in cαbles, wires, circuit breakers, lighting fixtures, switches, and non-tαmper-resistant sockets.

【NCV & IP66】 CAT Ⅲ 1000V, CAT Ⅳ 600V, and RoHS certified. The TN-213 voltage tester pen is equipped with an NCV probe to distinguish between live and neutral wire safely. The electrical tester is rated as IP66, providing both waterproof and dustproof capabilities.

【High & Low Sensitivity】 TN-213 suits different voltage detection ranges. Its detection range is 12-1000V at high sensitivity and 70-1000V at low sensitivity. Low range can be applied to motorized curtains, irrigation wiring, outdoor low-voltage lighting, etc. You can adjust the sensitivity mode by pressing the S button. As turned on, the tester will be on high-sensitivity mode by default

【User-Friendly Design】 This pocket-sized voltage tester comes with a convenient pen hook, allowing you to carry it in your shirt pocket with ease.
