Overview
The CI2000-RQD series thermal conductivity analyzer wholesale is a new intelligent industrial online analyzer that combines the world's thermal conductivity sensors with microcontrollers. The instrument operates based on different physical principles with varying thermal conductivity conditions for different gas compositions. Using platinum wire as a sensitive element to form an unbalanced bridge, the output signal size corresponds to the volume percentage of the measured gas. Then, this signal is amplified, filtered, linearized, and subjected to electrical processing such as standard signal output. After Z, a standard current or voltage signal proportional to the concentration of the measured gas is output.
