Wall-mounted methane concentration detector manufacturers for many years the supply of natural gas alarm device [Lyla (0531-58669819 15269173085) For details, please call us, gas gas alarm, gas leak detectors, gas leak detectors, gas leak alarm, gas The leak alarm products products are widely used in widely used in the pharmaceutical, chemical, petroleum, fire, electricity, metallurgy, bio-pharmaceutical, gas, mines, rare gases research manufacturers. ? Products are divided into RBK-6000 series {fixed} {portable RBBJ-T Series}. Reaches or exceeds the preset alarm value when the era of gas detected in the environment, the wall-mounted methane concentration detector immediately send out sound and light alarm to remind the user to take security measures, and drive the shut-off valve, exhaust fan, sprinkler system to prevent an explosion, fire, poisoning incidents occurred, in order to protect the security. Gas alarm, gas leak alarms, widely used in gas, petroleum, chemical, metallurgy and other flammable and explosive gases in dangerous places.
