Specifications
Measurement type
CO2 and H2O differential, non dispersive infrared
gas analysis. Atmospheric pressure and temperature compensation.
CO2 corrected for H2O, broadening and dilution. Auto zero. Open and
Closed mode. Two experimental channels
Range measurement
CO2: 0 - 2000 ppm, H2O: 0 - 75 millibar
Resolution
CO2 0.1 ppm at 3350 ppm, H2O 0.1 millibar
Response time
Selectable between 0.1 and 10 seconds (in increments of 0.1 seconds)
Cell volume
5 cm3
Repeatability
CO2 0.2 ppm at 350 ppm
Signal Noise
CO2 typically 0.2 ppm peak to peak at 350 ppm with 1 second response time. H2O typically 0.02 millibar peak to peak at 20
millibar with 1 second response time
Differential zero drift
CO2 at 350 ppm <1ppm/hr at 25º C typically <2
ppm in 24 hours. 0.12 ppm per ºC H2O at 20 millibar typically < 0.5 millibars in 24 hours. 0.02 millibar per ºC
Span drift
