This non-contact AC Tester is so popular in Australia that it is onboard most fire and rescue vehicles. It is paramount to the safety of rescue personnel where live voltage may pose a threat and impede rescue operations. The AC30 tester has a high and low setting for ease of use and has proven itself to be both strong and robust with its shock and weather-proof design. This lightweight, hand-held digital device can be programmed to suit any application and its large push buttons and bright red LED indication make it easy to use. There is no better non-contact AC detector on the market today.
