Thermal Conductivity Gas Analyzer 

Determining gas concentrations by measuring the thermal conductivity of the gas, CI2000-RQD analyzer uses advanced thermal conductivity sensor with single chip technology. It adopts platinum thread as sense organ to make up Imbalance Bridge, which output signal has a relationship with tested gas volume. And the single chip will magnify, sieve wavelength, modify linearly and criteria the signal by electric procedure. And then it will output direct ratio signal to the tested gas concentration.
