Shenyang Kechuang Chemical Co., Ltd. is mainly engaged in herbicides, fungicides, insecticides and other pesticides, and other fine chemical products manufacturing processing and application services. Because the production and management process of the product involves toluene, hydrogen sulfide, sulfur dioxide, oxygen, carbon monoxide, ammonia, hydrochloric acid and other toxic and harmful gases, which pose a serious threat to life and property safety. The project adopts the ASD5300C gas detector and JB-TB-ASD5100 gas controller to ensure the safe production of Shenyang KECtron.
