Non-contact Voltage: It will flash and beep when the device is close to AC voltage greater during the specified voltage range without touch the measured object, and also with the beep sound and LED to indicate to support enough safety measuring application. Ideal for breakpoint Test. Handy circuit tester for electricians, homeowners.
Dual Adjustable Sensitivity: The default AC voltage measurement range is 48-1000V, it can also measure 12-1000V by Pressing the S button; Which meets the need for selecting the most suitable sensitivity before testing on different occasions and different objects.
LED Flashlight: Equipped with white LED light along with the probe, you can use it in a dark environment. 3 minutes Auto power-off feature conserves and extends battery life.
SECURITY LEVEL: IEC rated CAT III 1000V CAT IV 600V, Meets CE requirements; The electrical tester is safely double insulated. High Voltage Alert to warn you of voltage above 90V, the screen turn red and the safety symbol on the screen shines.
SAFETY: This voltage tester has multiple alarms with sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency. At the same time, the screen will be red or green. Red means the high voltage and live wire are detected, and green means the low voltage and null wire are detected.
