The CG-200 Combustible Gas Detector is a compact, high-sensitivity tool designed to detect a wide range of combustible gases in industrial, commercial, and emergency response settings. It features TRI-Mode detection-visual, audible (85dB tick rate), and vibration alerts-which intensify with gas concentration. The 5 LED indicators display levels based on Low and High sensitivity settings, detecting methane concentrations from less than 50ppm up to 10,000ppm. With a flexible 16 in. gooseneck probe, it easily accesses hard-to-reach areas. The detector supports auto zero calibration in fresh air, a hold function, and auto power-off to conserve energy. It powers up in under 50 seconds and operates on a rechargeable Li-Po battery (with AC charger included). The CG-200 identifies gases like methane, propane, hydrogen, CO, ethanol, ammonia, and complex mixtures such as natural gas, paint thinners, and industrial solvents. Ideal for HVAC techs, maintenance crews, fire/rescue teams, lab personnel, and construction workers, it's essential for leak detection, safety inspections, and hazardous environment monitoring. Compact at 8.7 in. x 2.4 in. x 1.6 in., and lightweight (1lbs.), it's built for portable, professional-grade gas detection.
