Klein Tools® 12-1000V AC Non-Contact Voltage Tester & Flashlight
Detects 12 to 1000V AC with simultaneous visual and audible voltage indicators. Bright flashlight illuminates work area and may be used independent of voltage detection. Visual LED bar graph indicates the presence of voltage - the higher the voltage sensed, or the closer to the voltage source, the more LEDs light up. Bar graph visual voltage indicator utilizes up to five vibrant LEDs for easy interpretation and viewing. Audible voltage indicator beeps at a greater frequency the higher the voltage that is sensed, or the closer to the voltage source.
