Features：
Quick Combustible Gas Identification: Designed to rapidly identify the presence of combustible gases in the air, suitable for natural gas, LPG, methane, propane, and other carbon-based gases.
Wide Gas Compatibility: Supports detection of multiple common gases including methane (CH₄), ethane (C₂H₆), propane (C₃H₈), carbon monoxide (CO), and more.
Fast Response Time: Semiconductor sensor warms up in about 30 seconds and responds within 5 seconds at ≤500 ppm or within 2 seconds above 500 ppm.
Dual Indication System: Features an analog-style leak indication along with a sound alert for intuitive leak size evaluation.
Compact & Portable: Lightweight design powered by two AAA batteries, convenient for home, RV, workshop, and maintenance use.
User-Friendly Operation: Simple interface suitable for beginners and professionals, allowing quick evaluation of potential leaks.
