Every electrical current generates a magnetic field, so a non-contact voltage tester can detect current in a conductor without actually touching it, even if the conductor is insulated. It has an L ...

We’ve added the Milwaukee 2225-20 Non-Contact Voltage Tester with Laser Infrared Thermometer to the competition section. Using a non-contact voltage tester is the quickest and easiest way to ...

The non-contact voltage detector promotes lineworker safety. As a worldwide manufacturer of hot line tools and equipment, Hastings understands that every day has the potential to bring the unexpected ...

Hi-Line Utility Supply introduces the Super Tester voltage detector, which blinks and sounds an alarm when placed in an electrostatic field above the trigger threshold of the device. Hi-Line Utility ...

More than 1 million voltage detectors are being recalled because they could give a false "no voltage" reading. The recall involves about 1.2 million Southwire Company non-contact voltage detectors ...

The PRX-500 Proximity voltage detector features nine selectable voltage ranges from 120V to 500kV as well as an easy-to-use electronic touch pad with large buttons The PRX-500 Proximity voltage ...

In the video embedded below, he shows off a homemade voltage detector circuit that he constructed using a trio of BC547 NPN transistors. The circuit is pretty simple though very useful all the same.

The PRX-500 proximity voltage detector includes nine selectable voltage ranges from 120V up to 500kV The PRX-500 proximity voltage detector includes nine selectable voltage ranges from 120V up to ...
