In addition, a direct-reading immersed sensor is necessary to allow measurement without alte- ring the temperature and pressure parameters which have a direct influence on this dissolved gas. The CO₂ sensor allows the measurement of the partial pressure of carbon dioxide directly in the water, thanks to a specific membrane permeable only to gases covering an infrared sensor.
NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that passes through the optical filter.

· Since we can measure the sensor resistance, that means the only unknown term in the RHS of equation 5 is the concentration. In other words, if we can measure the sensor resistance in any known gas concentration, we can calculate R 0. As it happens, we do know the concentration of one of the gases in figure 2: Carbon dioxide.
