The Klein Tools NCVT-6 is a non-contact voltage tester (NCVT) with an integrated laser distance meter. It can detect voltage over the full-range from 12 to 1000 VAC and can measure distances from 2-Inch (51 mm) up to 66-Feet (20 m). The laser distance meter functions independently from the NCVT with a simple-to-use intuitive interface. Easy, single-button changes between voltage detection and laser distance measurements.
