Yongchang Electronic Shenzhen household gas alarm provides the cheapest, Shenzhen Yongchang manufacturers

Gas leak alarm is a very important gas safety equipment, it is safe to use city gas last a protection. Gas leak alarm by the gas sensor environments low concentration of combustible gases, by sampling circuit, the amount or digital transmitted to the controller or control circuit, when the combustible gas concentration exceeds the value of the controller or the control circuit is set, the control signals an alarm or shutdown the gas valve actuator or other actions by executing circuit. Combustible gas alarm, the catalytic combustion type, hot type gas sensors, as well as small amounts of other types, such as chemical battery type sensors. These sensors are the surrounding environment by adsorption of the combustible gas, the sensor surface in a chemical reaction or electrochemical reaction, cause changes in the physical properties of the electrical sensor. Gas leak alarm is widely used in many fields of urban security, residential, factories, companies, schools, families, villas, warehouses, resources, petroleum, chemical, gas transmission and distribution.
