Voltage Tester/Non-Contact Voltage Tester with Dual Range AC 12V-1000V/48V-1000V, Live/Null Wire Tester.

【SAFETY FIRST】: It will send out multiple alarms through sound and light. When the voltage is detected, 1 cell of light will be on and the pen will beep slowly. 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, there will be two cells light up, which means the detected voltage range is 48v-1000v, three lights with the highest frequency of beep means the range of voltage 12v-1000v.

【NON-CONTACT】: With NCV inductive probe for AC voltage; Just place the tip near a terminal strip, outlet, or supply cord. When the light turns red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Test. Handy circuit tester for electricians, homeowners.

【MUTISTAGE REGULATION OF SENSITIVITY】: Press the “SEN” button to adjust sensitivity. Low-sensitivity for detecting voltage within short distance. Medium-sensitivity for normal circuit in a moderate distance. The high one is for dangerous circuit in a long distance.

【SECURITY LEVEL】: IEC rated CAT III 1000V, Meets CE requirements; The electrical tester is safely double insulated.

【COMPACT DESIGN】: Bright LED flashlight for work in dim ares; ; Automatic Power Off after 3 minutes without operation or signal detection; Pocket-sized, pen hook allows you to carry it in your shirt pocket.
