H2S Sensor – Hydrogen sulfide Gas Detector

Learn about the 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.

H2S Sensor Features

1. Sensitivity and Specificity: H2S sensors are engineered to be highly sensitive to the presence of hydrogen sulfide, even at low concentrations.

2. Fast Response Time: H2S sensors are equipped with a fast response time, providing real-time detection of hydrogen sulfide gas leaks or emissions.

3. Wide Detection Range: H2S sensors are designed to detect a wide range of H2S concentrations, from trace levels to higher concentrations.

4. Robustness and Durability: H2S sensors are built to withstand harsh industrial conditions, including temperature variations, humidity.

5. Low Maintenance Requirements: Modern H2S sensors reduce downtime and ensure continuous and reliable H2S detection.

6. Alarm and Monitoring Capabilities: H2S sensors are often integrated into gas detection systems that include audible and visual alarms, as well as data logging and remote monitoring capabilities.

H2S Sensor Parameters


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.
