Features: 1. Non-contact voltage detection: measure the strength of the voltage, when the voltage is detected, the buzzer has an alarm sound and the red indicator light flashes. 2. Display: Equipped with a large display screen with backlight, the electric measuring pen can detect along the line. When the red light does not flash and the buzzer alarms and stops at the breakpoint position, the position is determined. 3. Temperature measurement: use the temperature measurement, connect the temperature measurement wire for measurement, and measure the current temperature without plugging in the wire. 4. Flashlight lighting: let you no longer be afraid of the invisible measurement position in the dark environment, and eliminate the risk of electric shock. 5. Induction probe: fully sealed insulating ABS material, sensitive and accurate, the probe is illuminated by LED lights. Description: The tester can sense non-contact, automatically shut down, support zero line detection, breakpoint detection, and adjustable sensitivity.
