Non Contact Hdiwousp Electrical Sensitivity Adjustable Review

🔥【Non-Contact Safer Voltage Tester】NCV induction probe can complete the test without physical contact, and the insulation operation ensures the safety of the test. In the range of 12-1000V, the non-contact voltage test pen can test the voltage of most devices in the home. Through different levels of LED lights and alarm sounds, it tells you the current voltage level in time. 🔥【Adjustable Sensitivity Switch】3 levels of adjustable sensitivity make the measurement more sensitive and flexible: the default is level 1 (1 beep) after power-on; click the "S" key once to enter level 2 (2 beeps); Click the "S" key once to enter level 3 (3 beeps). Finally, after reaching the third gear, if you press the "S" key again, it will return to the level 1. 🔥【High-Speed Measurement & Fast Response】As long as the AC Circuit Tester Tool detects a voltage, the LED in the test pen will light up and beep. The multifunctional electroscope with a sensitive NCV sensor head/precision circuit board, within the range of voltage tester 12V~1000V (50Hz / 60Hz), the measurement is more secure, sensitive, stable and intelligent. 🔔【Wire Fault Detection】When the indicator light becomes weaker and the buzzer alarm sound becomes slower, it can be judged as the power-off location. Regardless of the sensitivity of the socket tester, the response of the electroscope to the live wire is stronger and more obvious, with full brightness and rapid buzzing. Now, you don't have to call a professional electrician nor make contact with the wire just to know whether electricity runs through it. 🔦【LED Flashlight & Automatic shutdown】The high-brightness, low-power white LED flashlight helps to illuminate the work space in the dark; the combination of the illuminator and the probe makes it more convenient to use. If you forget to turn off the flashlight, the pen will automatically turn off when there is no operation within 5 minutes and no current is detected.
