Adjustable Sensitivity Non-Contact AC Voltage Tester & Circuit Detector with LCD Screen, LED Flashlight, Buzzer Alarm (12V-1000V) Live/Neutral Wire Identification
Product Description
Product Overview
The Adjustable Sensitivity Non‑Contact AC Voltage Tester is a handheld tool that detects alternating current voltage without direct contact. The tester operates across a range from 12 V to 1000 V AC, enabling use on a variety of circuits and wiring configurations.
Key Features
- Adjustable Sensitivity – The device can be set to respond to different voltage thresholds, allowing safe detection in environments with low or high voltage levels.
- LCD Display – A clear screen shows the voltage reading and status information at a glance.
- LED Flashlight – An integrated light source illuminates the area being tested, aiding visibility in dim spaces.
- Buzzer Alarm – An audible signal alerts the user when voltage is present.
- Live/Neutral Wire Identification – The tester indicates whether a detected voltage is connected to a live or neutral conductor.
Operation
To use the tester, power the device by attaching a suitable power source, then adjust the sensitivity slider to the desired level. Point the sensor near the wire or cable of interest. When voltage is detected, the LCD updates the reading, the LED lights, and the buzzer emits an alarm. The live or neutral designation appears on the display, aiding quick identification of circuit components.
Applications
Electricians, maintenance professionals, and hobbyists can use this tester when inspecting wiring, troubleshooting circuits, or verifying the presence of voltage before performing work. The non‑contact feature eliminates the risk of touching live conductors directly.
