Built-in advanced gas sensor and sound & light alarm to ensure precise and safe gas detection in hazardous applications.
Q: What is the working principle of gas analyzer?
A: A gas analyzer is a device used to determine the composition and concentration of various gases within a sample. The working principle involves the interaction of the gas type with specific detection methods. Typically, a gas sample is collected and introduced into the analyzer's sensing chamber. Different types of gas analyzers employ various techniques such as infrared absorption, electrochemical reactions, catalytic combustion, and mass spectrometry.
For instance, in an infrared gas analyzer, the gas sample is exposed to specific wavelengths of infrared light. Different gases absorb specific wavelengths, allowing the analyzer to measure their concentrations based on the absorbed light. In electrochemical gas analyzers, the sample causes electrochemical reactions on specialized electrodes, producing measurable electrical signals proportional to gas concentration. Catalytic combustion analyzers ignite gases on a catalyst surface and measure temperature changes to determine concentrations.
These principles enable gas analyzers to accurately and swiftly quantify the presence of gases like oxygen, carbon dioxide, carbon monoxide, methane, and more in various applications including environmental monitoring, industrial processes, and healthcare.
