Where p = partial pressure, Pabs = absolute pressure, and PH2O = 42 mmHg @35°C and 100% RH.
Mainstream CO2 Humidity Correction FactorEither BTPS or STPD can be selected as the humidity correction factor for the Mainstream CO2 readings. The formula for the correction calculation is:
Where p = partial pressure, Pabs = absolute pressure, and PH2O = 47 mmHg @37°C and 100% RH.
M3016A Mainstream CO2 Performance Specifications
CO2Range –4 to 150 mmHg (-0.5 to 20.0 kPa)
Accuracy after 20 minutes warmup and calibration:
For values between 0 and 40 mmHg:±2.2 mmHg (±0.29 kPa)
