Dual-Range Non-Contact Voltage Tester with Laser PointerThe 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. Features: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 systemsDual-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 supplyBright integrated laser pointer for identifying objects of interest at distance on the jobsiteSimple to use intuitive interface is easy to change between voltage detection ranges and easy to determine the currently active rangeDelivers simultaneous visual and audible voltage indicators when AC voltage is detectedAudible voltage indicator beeps at a greater frequency the higher the voltage that is sensed, or the closer to the voltage sourceBuilt to withstand a 9.9-Foot / 3-meter drop''Auto Power-Off'' conserves battery lifeScrew-thread battery capLightweight, compact tool with pocket clip provides convenient storage and quick accessCAT IV 1000V safety ratingWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
