Dual range non-contact voltage tester. Voltage tester detects 12V (volts) to 1000V and indicates the presence of voltage with visual and audio signals. Vibrant LED (light emitting diode) bar graph indicates voltage strength for easy viewing. Proximity sensor indicates voltage strength. Detects standard voltage in cables, cords, circuit breakers, lighting fixtures, switches, outlets, and wires. Non-contact detection of low voltage in security, entertainment, communication, environmental control, and irrigation systems. Features an integrated, rugged flashlight to illuminate work area. Auto power off conserves and extends battery life. IP67: dustproof and waterproof.
