[0002] Gas detector is an instrument for detecting gas concentration. It is suitable for dangerous places where flammable or toxic gas exists. It can continuously detect the content of the measured gas in the air within the lower explosion limit for a long time. It can be widely used in various industries such as gas, petrochemical, metallurgy, steel, coking, electricity, etc. where flammable or toxic gas exists. It is an ideal monitoring instrument to ensure property and personal safety. Gas detector uses high-performance catalytic combustion and electrochemical gas sensors as detection elements. The product has high sensitivity and fast response time. This product is an aluminum die-cast one-time molding shell with high explosion-proof grade and easy installation.
