Non-Contact Voltage Tester with Signal Strength, 12-1000V AC
The Klein Tools NCVT7 Non-Contact Voltage Tester is designed to detect 12 to 1000V AC in cables, cords, circuit breakers, lighting fixtures, switches, outlets, and wires without direct electrical contact. Its backlit LCD displays signal strength, while the three-color LED tip and adjustable audible alert provide additional indications as the tester approaches an AC voltage source.
Best Used For
- Electrical Troubleshooting: Quickly check for the presence of AC voltage in wires, outlets, switches, and other electrical components.
- Circuit & Equipment Checks: Identify energized conductors and components without making direct contact.
- Jobsite Electrical Service: Compact pen-style design and pocket clip make the tester convenient for everyday electrical inspections.
Key Performance & Safety Features
- 12-1000V AC Detection: Detects AC voltage across a broad range for residential, commercial, and industrial electrical applications.
- Signal-Strength Display: Backlit LCD bar graph provides a visual indication of signal strength, with more bars illuminating as voltage increases or the tester moves closer to the source.
- Three-Color LED Tip: Blue indicates low signal strength, red indicates high signal strength, and green indicates no voltage detected.
- Adjustable Audible Alert: Audible indication changes its rate to correspond with the displayed signal strength.
- IP54 Protection: Provides protection against dust ingress and water splashing from applicable directions.
- 6.5-Foot Drop Protection: Designed to withstand drops from up to 6.5 feet (2 meters).
What's Included
- 1 x Klein Tools NCVT7 Non-Contact Voltage Tester

Electrical Safety & Operational Note:
Broad 12V to 1000V AC testing range supports both standard line voltage (outlets, switches, cables) and low-voltage systems (security, doorbells, HVAC controls). Always verify proper tester operation on a known live circuit prior to inspecting de-energized wiring.
