Klein Tools Receptacle Testers are designed to detect the most common wiring problems in standard and GFCI receptacles. A convenient chart on the tester helps determine wiring condition in outlet, based on lights results. Conditions indicated: open ground, reverse polarity, open hot, open neutral, hot/ground reversed.

• GFCI Outlet Tester detects the most common wiring problems in standard and GFCI receptacles
• Electrical outlet tester works on GFCI outlets and confirms operation of the ground fault protective device
• Built to withstand a 6.6 ft. (2 m) drop
• Operating temp: 32-Degree to 140-Degree Fahrenheit (0-Degree to 40-Degree Celsius)
• Nominal Voltage: 110/125V AC at 50/60Hz in 3-wire outlet

The NCVT-3P is a non-contact voltage tester with an integrated flashlight. The voltage sensor detects 12 to 1000V AC and indicates the presence of voltage in cables, cords, circuit breakers, light fixtures, switches, outlets and wires as well as AC voltage in doorbells, thermostats, low voltage lighting and irrigation systems. Includes both visual and audible signals. The NCVT-3P is rugged enough for any job site.

• Non contact voltage tester's dual-range capabilities allow tester to detect from 12 to 1000 V AC or 70 to 1000V AC for a broad variety of low-voltage or standard voltage applications
• Detects voltage with simultaneous visual and audible voltage indicators
• Bright flashlight illuminates work area and may be used independent of voltage detection function
• Green light indicates no voltage
• Lightweight, compact tool with pocket clip provides convenient storage and quick access
• Auto power-off feature conserves and extends battery life
• CAT IV 1000V rating provides expanded operation and protection
• Screw-thread battery cap with O-ring ensures protection against dust and water ingress
• 6.6 ft. (2 m) drop protection
• IP67: Dustproof and waterproof
• Conforms to CE requirements
• US Patent 10,073,142, D750,985 and other patents pending
