The biogas analyzer is designed according to the composition and characteristics of biogas and is used to detect the contents of gases such as methane, carbon dioxide, and hydrogen sulfide in biogas. It combines multiple detection technologies such as infrared absorption and electrochemical sensing to ensure the accuracy of detection results. The outer shell is made of corrosion - resistant and explosion - proof materials to adapt to the harsh environment of biogas production and treatment. The internal structure is reasonable, with functional modules such as sampling, purification, and analysis. Its advantage lies in its ability to accurately measure the concentration of each component in biogas, providing data support for the utilization and purification of biogas; simple operation and easy maintenance; and strong adaptability, being usable in biogas projects of different scales. It is widely used in fields such as biogas power generation, biogas purification, and sewage treatment to improve the utilization efficiency and economic benefits of biogas.
