Voltage Detectors are pen-shaped pieces of testing hardware that helps determine the presence and absence of current in a circuit without any direct metallic contact required. A voltage detector should have a range of voltage capabilities stated on either the device itself, the packaging, or manual that comes with it. It also detects audio and visual cues and alerts the user on any present voltage
These detectors are rated and tested for particular voltage range use. If you are a skilled and a professional electrician, voltage detector is something you should invest in.
When shopping for a Voltage Detector, you’ll want to be sure to keep an eye out for these essential features.
- Design: Find a user-friendly voltage detector. Make sure that it is lightweight, easy to hold and easy to operate. It is best to have it portable so you can have it with you when you need to.
- Versatility: If you want a voltage detector which has a variety of functions, you need to check its versatility. Some testers can measure resistance, voltage, current, transistor, continuity, and diode testing.
- Ability and Functionality. Be sure to check its range and compatibility that is fair enough to use at home and by professionals. Also, look for a detector with at least two indicators available- LED glow or buzzer.
We’ve done the research and read hundreds of customer reviews to bring you our curated list of the top 10 Voltage Detectors.
