Low Voltage Detectors

A voltage detector is a device that determines the presence or absence of an electrical charge in an object. It can be a simple, pen-shaped piece of testing hardware that indicates the existence of electricity or an advanced tool that detects precise voltage levels in electrical systems.

This detector employs visual or audio cues to alert the user if a voltage is present. Certain types of detectors use lights and numbers for indicating the voltage level.

The detectors are tested and rated to use within certain ranges of voltage. Using the voltage detector on a higher voltage than that for which it is designed will provide inaccurate results and could also be dangerous.
