Safety design, Senses the steady state electrostatic field produced by ac voltage through insulation without requiring contact to the bare conductor. A red glow at the tip indicates the presence of voltage

Non-contact detection of voltage in cables,cords,circuit breakers,lighting fixtures,switches,outlets,and wires.
Highe intensity,bright green LED indicates the tester is operational and aids in illuminating the workspace.
When voltage is detected,a high intensity,bright red LED illuminates and a beeping sound is generated.
Discrete digitally controlled ON/OFF power button.
Auto power-off feature conserves and extends battery life.
Microprocessor controlled low-battery indicator and tester shutdown.
CAT IV 1000 Volt rating provides expanded operation and protection
50 to 1000 Volt AC power operating rang allows broad application.
Durable polycarbonate plastic resin construction.
Lightweight compact design with a convenient clip to fit securely in your pocket.
