description non-contact voltage tester w/laser the klein tools ncvt-5a is a dual-range non-contact voltage tester (ncvt) with integrated laser pointer. the tester can be set to detect voltage from 70 to 1000v ac (mode 1) or from 12 to 1000v ac (mode 2). high pitched audible alerts beep at greater frequency as higher voltage is sensed, or proximity to the voltage source gets closer. the laser pointer can function independent of or simultaneously with the ncvt. cat iv 1000v safety rating. non-contact voltage tester with laser pointer detects ac volts. volt tester tests 70 to 1000vac voltage in cables, switches, etc. 12 to 1000vac range for low voltage in security, irrigation, etc. audible voltage indicator beeps at a greater frequency the higher the voltage that is sensed, or the closer to the voltage source. built to withstand a 9.9-foot / 3-meter drop. auto power-off" conserves battery life. screw-thread battery cap. lightweight, compact tool with pocket clip provides convenient storage and quick access. cat iv 1000v safety rating. us patent no. d750985. for more than 160 years, klein tools has manufactured premium-quality, professional-grade hand tools that deliver the performance, durability and precision needed to get the job done right. our family of engineers, workers and craftsman continue to put six generations of expertise into every tool we create by using only the highest quality materials, superior workmanship, and keeping manufacturing as close to home as we can. klein isn't just the name of our company, it's also our family name. and since we're an american company that's family-owned and family-run, you know you can count on us to be here tomorrow. klein tools doesn't just make great products, we make great products that stand up to the demands of the professionals who use them every day ... since 1857. california proposition 65 warning. view warning label features voltage tester provides non-contact determination of ac voltage in cables, cords, circuit breakers, switches, outlets and wires, as well as ac voltage in security, entertainment, communications, environmental control and irrigation systems dual-range testing: select 12 to 1000v ac which is perfect for low voltage systems such as doorbells, environmental control or irrigation systems, or select 70 to 1000v ac which is perfect for detecting systems such as electrical mains supply bright integrated laser pointer for identifying objects of interest at distance on the jobsite simple to use intuitive interface is easy to change between voltage detection ranges and easy to determine the currently active range delivers simultaneous visual and audible voltage indicators when ac voltage is detected audible voltage indicator beeps at a greater frequency the higher the voltage that is sensed, or the closer to the voltage source built to withstand a 9.9-foot / 3-meter drop "auto power-off" conserves battery life screw-thread battery cap specifications acme tools brand name klein tools acme tools part number ncvt-5a assembled weight (lbs) 0.093 battery quantity required 3 battery size aaa california proposition 65 warning required yes color / finish yellow country of origin china dc polarity indicator not applicable dc voltage 1000 digital display not required globaltradeitemnumber (gtin) 00092644692949 internal supplier part # ncvt5a internet product code (ipc) 7b3d98adc67 manufacturer warranty please refer to attached warranty document. material plastic package depth 9.56 package height 1.94 package weight 0.26 package weight (lbs) 1.5 tester type voltage upc 092644692949
