Product Description
HD9300 four-in-one gas detector is a high-performance fixed gas detector developed by our company for long-term continuous monitoring of oxygen, combustible gases, hydrogen sulfide, and carbon monoxide in the air, generally installed in places where flammable and explosive gases are easily leaked and in chemical plant areas where toxic and hazardous gases exist.
The gas detector can be widely used in petroleum, chemical, liquefied gas, coal, pharmaceutical, metallurgical, municipal and other industries, and can be installed in petroleum gas pipeline networks, chemical plants, sewage treatment plants, coal mines, refrigeration workshops, gas station areas, boiler rooms, hotel kitchen operation rooms and other places that require anti-toxic and explosion-proof. It is the ideal monitoring equipment to ensure the safety of people and property and to prevent the leakage of toxic and harmful gases.
