Review on Protmex AC Voltage Tester Pen - Non Contact Voltage Detector with Adjustable Sensitivity, Electrical Circuit Testers, Flashlight and Buzzer Alarm - Multi Range AC 12-1000V, Live/Null Wire Judgment by Anthony Gupta
Modified Light Switch
Thanks to this little gadget I'm an electrician now. Turn off the power in the box and swing it around the wire terminals to find the hot wire and then boom, you're an electrician too. Do that.
Pros
- Different Voltage Test and Dual Range Test - Distinguish between hot wire and neutral wire with different frequency audio alarm; The default AC voltage measurement range is 48-1000V, it can also measure 12-1000V by adjusting the sensitivity. This corresponds to the need to select the most appropriate sensitivity in different cases and on different objects before testing.
Cons
- Good but not great
