- Manufacturer Name :Klein Tools
The Klein Tools NCVT3P is a dual-range non-contact voltage tester designed to detect AC voltage from 12 to 1000V. It combines visual and audible voltage indicators with an independent flashlight for testing cables, outlets, switches, circuit breakers, and low-voltage systems.
- Klein® NCVT3P Dual Range Non-Contact Voltage Tester With Flashlight, 70 to 1000 VAC/12 to 1000 VAC Max Measurable
Dual-range AC voltage detection: Detects low voltage from 12 to 70V AC and standard voltage from 70 to 1000V AC, supporting a broad range of electrical testing applications.
Non-contact voltage testing: Detects AC voltage without direct conductor contact for convenient voltage checks.
Visual and audible indicators: Provides simultaneous LED and audible alerts when voltage is detected, making results easy to identify.
Green no-voltage indicator: A green light indicates when voltage is not detected.
Integrated flashlight: Illuminates the work area and operates independently of the voltage-detection function.
CAT IV 1000V rating: Supports operation in CAT IV environments up to 1000V.
IP67-rated construction: Dustproof and waterproof housing helps protect the tester against dust and water ingress.
6.6 ft (2 m) drop protection: Designed to withstand drops from up to 6.6 ft (2 m).
Auto power-off: Conserves battery power when the tester is not in use.
Screw-thread battery cap with O-ring: Helps protect the battery compartment against dust and water ingress.
Compact design with pocket clip: Provides convenient storage and quick access while working.
Batteries included: Supplied with two AAA batteries and provides up to 125 hours of battery life.

The listed product information does not specify DC voltage detection.
What voltage range does the Klein Tools NCVT3P detect?
The NCVT3P detects AC voltage from 12 to 1000V. Its low-voltage mode covers 12 to 70V AC, while its standard-voltage mode covers 70 to 1000V AC.
Does the NCVT3P need to contact the conductor?
No. The NCVT3P is designed for non-contact detection and testing of AC voltage.
How does the tester indicate the presence of voltage?
The tester uses simultaneous visual LED and audible beep indications when AC voltage is detected. A green light indicates when voltage is not detected.
Can the flashlight be used without testing for voltage?
Yes. The integrated flashlight can operate independently of the voltage-detection function.
