Pocket-Sized Voltage Tester
The Mastfuyi non-contact voltage tester detects AC voltage from 12V to 1000V without touching live parts. It suits electricians, automotive technicians and DIY users who need fast safety checks on outlets, terminals and cords. A built-in clip secures it in a pocket for quick access on the job.
Dual Sensitivity and Current Reading
Select high sensitivity for 12V to 1000V detection or low sensitivity for 48V to 1000V to reduce ambient interference. The tip groove allows multi-wire current measurement by wrapping a cord around it at least twice, removing the need for a separate clamp meter during basic checks.
Visual and Audible Alerts Under Load
Red light and a high-pitched beep signal high voltage, while yellow light and a low-pitched beep indicate low voltage. Non-contact detection varies with distance, so consistent positioning gives repeatable results during sustained inspection of live circuits.
