The amiciSense Flammable Gas Leak Detector Pen is a compact and reliable safety tool designed to help you quickly identify gas leaks before they become dangerous. With a detection range of 50 to 1000 PPM, it can sense even small traces of flammable and combustible gases such as methane, LPG, natural gas, acetylene, alcohol vapors, gasoline fumes, and more. Once a leak is detected, the device immediately triggers a dual alarm system—a bright red LCD display and a loud 70 dB audible alert—so you can take action without delay. The fast response time of under 5 seconds ensures timely warnings in critical situations.
