Non-Contact Voltage Tester Pen - Dual Range AC Voltage Tester 12V/48V-1000V, Live/Null Wire Circuit Detection Tester Breakpoint Finder Electrical Outlet Voltage Detector, Measure AC Circuit Tester
- ...rtification. When the ac electrical tester pen detects a voltage, the probe will flash red and beep, the higher the detected voltage, or the closer it is to the voltage source, the dual range voltage detector will beep at a higher frequency. The ac socket tester detects low voltage and neutral and triggers a yellow flashing light, and detects high voltage and live wire triggers a red flashing light.
- Non-Contact: The ac circuit tester uses a non-contact method to measure voltage, with an NCV induction probe for detecting ac voltage, you only need to place the tip of an electric circuit detector near an outlet or power cord to detect the presence of voltage.The dual range circuit voltage tester is a safe double insulation, you don't have to worry about being shocked, voltage detector tool is very safe, and it is an ideal device to help determine the neutral or live line and breakpoint testing.
- Dual Range: The electrical current tester detects standard voltage and low voltage ranges (12-1000V AC / 48-1000V AC), making the measurement more flexible and accurate. NCV sensitivity is automatically adjusted from low to high, low sensitivity can detect doorbells, thermostats, power strips, etc., high sensitivity is ideal for detection systems such as power supp....
