NonDispersive Infrared, NDIR, Carbon Dioxide Sensors ...

+

Nondispersive infrared, often called NDIR, sensors deliver high accuracy and fast response time. NDIR sensors have no contact with the gas, making them more reliable, and are constructed for specific gases so that they are unaffected by other gases. NDIR sensors are the most reliable method for detecting carbon dioxide gas.

CO2 sparging will not impact the DO measurement using an optical DO sensor. CO2 can impact traditional polarographic DO sensors over time thus more frequent electrolyte replacement may be needed. When should I calibrate my DO sensor? The frequency of calibration will depend upon the duration of process runs and the accuracy required for process control. In bioreactor applications …
