Tester Klein Tools NCVT-3 Non-Contact Voltage

The NCVT-3 is a non-contact voltage tester with an integrated flashlight. The voltage sensor detects 12-1,000V 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.

  • Provides non-contact detection of AC voltage
  • 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 function
  • 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/viewing
  • Audible voltage indicator beeps at a greater frequency the higher the voltage that is sensed, or the closer to the voltage source
  • “Auto Power-Off” conserves and extends battery life
  • Screw-thread battery cap with O-ring ensures protection against dust and water ingress
  • Provides non-contact detection of AC voltage

Voltage Tester Non Contact AC Circuit Voltage Detector 

  • High Sensitivity & Dual Detect Mode : The default auto AC voltage measurement range is 48-1000V, besides, you can also push Mode Button to switch on manual mode with larger measurement range between 12-1000V. Meet all your needs.
  • LED Flashlight & Visual Audible Indicator: Sensor indicators emit yellow and red lights, and the buzzer alarms at different frequencies (low, mid, high). Visual and audible alarm to secure your safety. Led flashlight design makes you more convenient to work in dim/ dark environment.
  • Live/ Zero Line Distinguish: This non-contact voltage tester can easily distinguish live line and zero line. According to different signal indicator, strong insistent beeps within red induced signal light is live line.
  • Safe and Reliable: CE CAT III 1000V certificated, this voltage detector pen adopts ABS and PVC material, no exposed metals or conductive parts, all advanced insulation, safe and reliable.
  • What’s More: 1* Voltage Tester, 1* 9V Battery, 1* User Manual, 24-Month Warranty and friendly effective customer service.
