Non-contact voltage probes have been around a while and some test equipment now has them built-in. This is one of those things that you probably don’t think about much, but surely it isn’t ...

We’ve seen various types of non-contact voltage and current sensing over the years. We’ve even seen biological voltmeters lately.

This lets electricians fine-tune the detection range for accurate readings across different voltage levels in various systems. Two popular options are: non-contact testers, ideal for initial ...
