Klein Tools NCVT-5A Dual-Range Non-Contact Voltage Tester with integrated laser pointer detects 70 to 1000V AC (Mode 1) or 12 to 1000V AC Mode 2). Audible alerts increase in frequency as voltage level rises or as you move closer to the source. Laser operates independently or with voltage detection. Class IIIa laser (21CFR1040.10 and 1040.11 - IEC60825-1 Ed.3) with an output power of less than or equal to 5mW at 630-670nm. CAT IV 1000V safety rating.
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
