Detection of ultra-high concentration hydrogen sulfide gas

Hydrogen sulfide is a colorless, flammable acid gas under normal conditions. low, it has a foul smell, like rotten eggs, but when the concentration is high, it does not smell (because a high concentration of hydrogen sulfide can paralyze the olfactory nerve).

When a major accident or natural disaster occurs and the air contains ultra-high concentrations of hydrogen sulfide, it is necessary to quickly measure the concentration of hydrogen sulfide to take action.Nippon Light Physical and chemical hydrogen sulfide detection tube, model 120UT can measure 5- For 40% concentration, you just need to use an aspirator to connect the gas detection tube to extract 50ML of gas, and you can get the detection result in 1 minute. H2S+CUSO4→CUS, The agent in the detection tube changes from light blue to black, and the scale corresponding to the color changing interface is the concentration of hydrogen sulfide gas. If you can also use a 5 meter to 10 meter extension tube to protect the safety of the measuring personnel, you can still get the measurement results safely and accurately.
