🔌 Adjustable Sensitivity Voltage Tester - Tiancai Non Contact Electroscope with LED Flashlight, Buzzer, Display Screen & Pocket Clip | High-Precision Smart Tool for 12V-1000V Testing Review

🖊【Non-contact, safer】In the range of 12-1000V, the non-contact voltage tester pen can test the voltage of most equipment in the home. Place the product tip on the lamp holder, power socket or near the point wire, the indicator light will be based on the signal strength Light up the corresponding indicator, and the buzzer sounds an alarm, you can know the voltage here. 🖊【One-key sensitivity switching】voltage tester has 3 levels of sensitivity to choose from. After power-on, it defaults to low gear (one buzzer sound); press the "S" key to enter the middle gear (two buzzer sounds); then press "S" "Key to enter the high gear (three buzzer sounds), then press the "S" key to return to the low gear (buzzer beep once), in this cycle. Shield interference and test accurately. 🖊【High-speed measurement, fast response】Voltage tester meter pen is a multifunctional electroscope with sensitive NCV sensor head / precision circuit board, in the range of voltage tester 12V ~ 1000V(50Hz/60Hz), the measurement is safer, sensitive, stable and intelligent. 🖊【Line power failure detection & zero live wire detection】Use a Voltage Detector Pen to detect along the wire line. When the indicator light becomes weak and the buzzer alarm sound becomes slow, it can be judged that it can be judged as the power failure position.No matter what gear the sensitivity of outlet tester is, the response of the electroscope to the fire line is stronger and more obvious, the brightness is full, and the buzzing sound is rapid. 🖊【LED flashlight & pen clip design】Voltage tester pen comes with a flashlight, which can be called a voltage tester light. Press the flashlight switch key to turn on/off the flashlight; if the flashlight is not turned off, the pen will automatically turn off/off when there is no operation within 5 minutes and no current is detected.A voltage tester with a Pocket clip. When not measuring, the electric pen can be hung on clothes / trouser pockets at will.
