| Abstract: | To overcome the existing problems in the conventional infrared gas analyzers, the critical teclmologies of a new non-dispersion infrared ternary gas analyzer was researched by using the principle of analyzing non-dispersion infrared gas. The advanced technologies include quad thennopile infrared detector, lock-in amplifier circuit, MSP430 ultra-low power consumption single chip computer, anti LCD display module, etc. By using this analyzer, the ternary gas of carbon monoxide, carbon dioxide and methane can be continuously analyzed simuhaneously, and the instrument will have broad prospects in applications. |
