Klein recently announced the NCVT-3, a non-contact voltage detector capable of detecting AC voltage between 12 and 1,000 volts. When voltage is detected it provides visual and audible alerts to the amount of voltage and to the tester’s proximity to it; more illuminated LED bars and faster beeping indicate higher voltage and/or closer proximity to the voltage source.
Features include a pocket clip and a built-in flashlight that allows the unit to be used to illuminate the work.
Klein is not the first company to build a flashlight into a non-contact voltage detector—Fluke, Flir, and others do too. According to Klein, what sets their tool apart is its durability. It has been subject to dust and water testing and given an ingress protection (IP) rating of IP67. The first digit is a measure of dust resistance; 6 means the tester is impervious to dust. The second digit has to do with water resistance; 7 means the tool can be immersed a meter (3.3 feet) deep in water without being damaged. Klein’s non-contact voltage tester has a safety rating of CAT IV 1000V (which is common enough) and drop testing has shown it will not be damaged by falls of up to 2 meters (6.6 feet).
