Conclusion

A non-contact DC voltage tester is a great tool for quickly and easily determining if there is voltage present in a given area. This type of tester is very easy to use, and can be a great asset in any home or office.

While there are a few different types of non-contact DC voltage testers on the market, they all operate in a similar manner. Simply hold the tester near the area where you believe there may be voltage, and if the tester lights up or beeps, then there is voltage present.

This type of tester is an essential tool for anyone who works with electricity, or who needs to quickly check for the presence of voltage.
