The JY-CA339 Series Wall-mounted Household Combustible Gas Detectors are engineered for detecting various combustible gases such as methane and propane. Utilizing a semiconductor detection principle and free diffusion sampling method, the detector can measure gas concentrations within a range of 0~20%LEL. With a rapid response time of ≤20 seconds, the device is highly efficient in providing early warnings. Powered by AC220V/50Hz, it is ideal for home safety setups.
