Klein Tools NCVT1XT Non-Contact Voltage Tester Pen 70V to 1000V AC

The Klein Tools NCVT1XT Non-Contact Voltage Tester Pen operates as a pocket-sized electrical safety detector engineered to identify live AC voltage without physical contact with exposed conductors. Featuring a 70V to 1000V AC sensing range, an IP67 waterproof and dustproof rating, a 9.8-foot drop test rating, and a CAT IV 1000V safety classification, this voltage stick identifies live electrical fields in circuit breakers, cables, switches, and wall outlets. Weighing 1.7 ounces and powered by two AAA alkaline batteries, this tester uses a green power-on LED alongside simultaneous flashing red visual indicators and audible tones to confirm active electrical current.

Best Used For:

  • Circuit Breaker & Electrical Panel Testing: Checking live circuit breakers, busbars, and distribution panel wiring before performing electrical maintenance.
  • Wall Outlet & Appliance Cable Verification: Detecting active voltage in wall receptacles, light fixtures, extension cords, and industrial equipment switches without stripping insulation.
  • Severe Weather & High-Dust Jobsite Inspections: Testing electrical systems in rainy, muddy, or airborne-grit environments utilizing the IP67 sealed polymer housing.

Key Performance & Safety Features

  • 70V to 1000V AC Non-Contact Detection: Senses standard electrical fields across a 50Hz to 500Hz frequency range without direct conductor contact.
  • IP67 Waterproof & Dustproof Enclosure: Sealed polymer body prevents water ingress during heavy downpours and blocks dust contamination.
  • 9.8-Foot Impact Drop Protection: Industrial-grade housing withstands accidental 9.8-foot drops onto hard concrete floors.
  • Dual-Sensory Live Alert System: Emits a high-volume audible warning tone and flashes a bright red LED when energized circuits are detected.
  • CAT IV 1000V Safety Certification: Rated to withstand high-voltage transient surge spikes encountered in utility and industrial electrical installations.
  • Power-Saving Automatic Shutdown: Microprocessor automatically powers down the tester after inactivity to preserve battery life.

What's Included

  • (1) Klein Tools Non-Contact Voltage Tester Pen (NCVT1XT)
  • (2) 1.5-Volt AAA Alkaline Batteries
  • (1) Comprehensive Operator Instruction Manual

Pro-Tip: Always perform a "Live-Dead-Live" test before working on electrical circuits. Test the Klein NCVT1XT on a known live voltage source first to confirm the green LED, red flashing light, and audible alert function correctly, test the target circuit to ensure it is de-energized, and then re-test on the known live source to verify tester operation.
