NCVT-6 NON-CONTACT VOLTAGE TESTER WITH LASER DISTANCE METER 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 12-1000VAC and can measure distances from 2" (51mm) up to 66' (20m). 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.
