Non Contact Voltage Tester Pen, AC 12/48-1000V Electric Tester Pen | Electrical Tester Pen, Dual Sensitivity AC Checks, Live/Neutral Wire ID, Audible/Visual Alarm, LED Light, CAT III/CAT IV
Non-Contact AC Voltage Detector Pen: Check AC voltage without touching conductors. Supports high sensitivity 12-1000V and low sensitivity 48-1000V for wires, switches, socket holes, and basic AC electrical checks.
Dual Sensitivity AC Checks: Select high or low sensitivity before detection. High sensitivity is for about 12-1000V AC, while low sensitivity is for about 48-1000V AC. Avoid switching sensitivity during detection.
Live/Neutral Wire Identification: Compare the signal strength near two wires or between socket holes. A stronger signal indicates the live wire; a weaker or no signal indicates the neutral wire in this comparison method. No alarm alone does not confirm the absence of voltage.
Audible and Visual Alarm: When AC voltage is detected, the electric tester pen beeps and lights 1-3 signal indicators by signal strength. Faster beeps and more lights indicate a stronger or closer AC voltage source.
CAT Rated Safety for AC Checks: CAT III 1000V/CAT IV 600V rated with ABS housing, low-battery alert, LED flashlight, auto shutoff, and pocket clip. For AC voltage checks only; test on a known live source before use.
