Product Description

HD9300 is generally installed in places where flammable and explosive gases are easily leaked and in chemical plant areas where toxic and hazardous gases exist.

The instrument adopts high-performance catalytic combustion and electrochemical gas sensors as detection elements, which have the advantages of good repeatability and temperature and humidity characteristics, long service life, easy operation, and strong anti-interference performance. It is suitable for gas concentration detection in an industrial environment. Hangwei Sensors ar Best Fixed Gas Detectors Provider from China.

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.
