DQJ-50-type multi-gas detector

DQJ-50-type multi-gas detector that is related with the use of multi-gas detector tube can be quickly measured ambient air concentrations of carbon monoxide, carbon dioxide, hydrogen sulfide, sulfur dioxide, nitrogen dioxide, ammonia, oxygen, hydrogen and other gases . Features and application: DQJ-50-type multi-gas detector, mainly for the coal mine, metallurgy, chemical industry, coking, gas station, engineering, environmental protection and health and epidemic prevention stations and other departments, for rapid determination of carbon monoxide in ambient air field the concentration of carbon dioxide, hydrogen sulfide, sulfur dioxide, nitrogen dioxide, ammonia, oxygen, hydrogen and other gases. When to ensure safe production, prevention of disasters and reliable detection equipment. The instrument is easy to carry, simple, rapid, highly sensitive, especially in the immediately ascertain the harmful gas components, and the presence of dangerous concentrations, is an effective tool essential. How it works: the sampler and the cylinder by the inverter ① ⑨ two major components. The piston head is used to extract and press the gas switching valve may be changed or cut off the gas flow direction of the air flow when the valve is in the illustration and joint ⑤ ③ the same direction, the cylinder ⑨ and joint communication; when the valve clockwise to ③ When the piston cylinder is rotated to ⑨ in the same direction, and the piston cylinder gas nozzle ② ⑨ interlinked; ③ valve in the corner of the two parties want straight line bisecting the angle (about the angle between the cylinder axis 45 °), switching valve piston cylinder gas cut off from the outside world. The cylinder gas volume (ml) inhalation engraved on the rod ⑧ scale can be shown handle? Pull a position. Coupling connector ⑤ is sampling and testing pipe.
