H2S Sensor – Hydrogen sulfide Gas Detector


SKU: N/A Category: Tag:

H2S Sensor

H2S sensor is a wall-mounted gas sensor that can detect the concentration of hydrogen sulfide gas in the air environment. The shell is dust-proof and waterproof, and the service life is long. Protection grade IP65, can work normally in harsh environment. A temperature and humidity probe at the bottom supports simultaneous measurement of temperature, humidity, and hydrogen sulfide. Hydrogen sulfide detector is suitable for parking lots, garages, workshops, chemical plants, greenhouses, closed living places and other occasions.

Hydrogen sulfide Gas Detector

View – H2S sensor

Hydrogen sulfide is a colorless, odorous, flammable gas, which is irritating and suffocating, it is harmful to the human body. Renke hydrogen sulfide sensor adopts electrochemical principle, which is sensitive in response and strong in anti-interference ability. In order to meet the requirements of different places, we provide four types: wall-mounted H2S sensors, duct type H2S sensors, portable H2S detectors and fixed H2S detectors.


What is hydrogen sulfide gas?

Hydrogen sulfide is an inorganic compound with a molecular weight of 34.076. It is soluble in water with a melting point of -85.5 ℃ and a boiling point of -60.4 ℃. Under standard conditions, hydrogen sulfide is a flammable acid gas with no color and a rotten egg odor at low concentrations.

What is a hydrogen sulfide sensor?

Hydrogen sulfide sensor is a gas sensor designed to detect hydrogen sulfide. Hydrogen sulfide is a colorless flammable gas with a special smell of rotten eggs. It is irritating and asphyxiating, and has great harm to human body. At present, the colorimetric method and gas chromatography are mostly used to determine hydrogen sulfide in air.

Why test for hydrogen sulfide?

Hydrogen sulfide is mainly produced in municipal sewage pipes, manure tanks, mines, pulp mills…. Where the air is not circulating, the lack of ventilation leads to the continuous accumulation of hydrogen sulfide gas, which leads to the rising concentration of conditions. That’s why there are so many cases of grief.
