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.Features Delivers simultaneous visual and audible voltage indicators when AC voltage is detected Simple-to-use intuitive interface; easy single-button changes between laser distance measurements and voltage detection Built to withstand a 6.6-Foot (2 m) drop Ingress Protection IP40 Dust Resistant Screw-thread battery cap CAT IV 1000V safety rating High-visibility reverse contrast display for better viewing in low light conditions Under normal operating conditions, at distances from 2-Inch to 32.8-Foot the NCVT-6 has an accuracy of +/- 1/16-Inch; and at distances greater than 32.8-Foot up to 65.6-Foot, accuracy of +/- 1/8-Inch Laser Class II, 630 to 670nm, Max.
