Electrical testing

Safe isolation is our first and most important action before working on electrical circuits, Kewtech's two pole tester range offers several reliable solutions working together with the unique Kewprove proving unit and universal Kewlok locking out device. Kewtech were the fisrt to launch an advanced socket tester, the Loopcheck 107, that not only tests for polarity at the socket, but also the quality of the earth loop and whether the mains polarity is correct on the incoming supply, something your standard tester will not do.
