We spent eight months talking with electricians and testing seven models to find the best and safest non-contact voltage testers. Here’s what we discovered.

This Simple Voltage and Current tester can be used to measure the forward Voltage drop and current through Semiconductor Diodes like LED, Infrared diode, Photo diodes, Silicon diodes etc. This is ...

The tester features a pair of powerpole connectors, which are used quite often for connecting HAM gear. A PIC12F675 runs the show, acting as an adjustable comparator for detecting voltage levels.

Next, I will use "COOWOO USB current voltage trigger meter" which can be said to be upward compatible with the "COOWOO USB current voltage tester checker" we have reviewed so far.

Fluke’s most rugged Two-Pole Voltage Tester with improved safety features gives you peace of mind; now available with additional warranty and a free holster Fluke announces its most rugged Two-Pole ...

Voltage testers and meters have been around for years, but most of them had two probes or tips that required you to be in contact with the electrical wire to check its voltage.

The VT50 two-pole voltage tester doubles as a GFCI tester. The tester’s LEDs indicate five different levels of voltage from 12V to 400V, either AC or DC. It can be hung around the user’s neck to free ...
