Description of 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

Adjustable Sensitivity️: Dual Range 12V-1000V / 48V-1000V-choose different range according to your needs. Different Voltage Test & Dual Range Testing - Distinguish the live and null wire through different frequency alarm sound; The default ac voltage measurement range is 48-1000V, it can also measure 12-1000V by adjusting the sensitivity. Which meets the need for selecting the most suitable sensitivity before testing on different occasions and different objects. Non Contact Voltage Tester - It will flash and beep when the device 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. Safely Sound & Light Alarm - Voltage frequency can be distinguished by beep and LED indicator. It's loud enough to hear over moderate machine equipment noise. Small in size, easy to store in tool box or carry in your pocket. LED light & Low Voltage Indicator - The shining prompt of low voltage LED and alarm can warn you to replace the battery in time, while the white LED light allows operating even on dark environment; Auto power off after no operation for 5 mins to save energy

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

The tester wasn't exactly

The tester gave incorrect readings. Sometimes this interfered with the power supply, which wasn't the case. Basically the problem was that there would be indications of no power causing damage to other equipment. Wouldn't recommend it.

Pros
  • Non-Contact Voltage Tester - it flashes and beeps when the device approaches an AC voltage that exceeds the specified voltage range without touching the object being measured, and with an audible alarm and LED to indicate adequate security measurement application
Cons
  • Some errors

Pretty cool stuff

Easy to use sensitive detector. This gives you peace of mind before doing any electrical work. I also have a voltmeter, but I have a feeling I'll need it most of the time. Thanks to technology.

Pros
  • Safely Sound & Light Alarm - The frequency of the voltage can be determined by the sound signal and the LED display. It's loud enough to hear moderate engine noise. Small size easy to store in a tool box or bag
Cons
  • Do you have problems
