CIRAS-SC
PP Systems CIRAS-SC single channel infrared gas analyser

The CIRAS-SC is a single channel infrared gas analyser for accurate, absolute measurement of CO2 and H2O in µmol -1 of a single gas stream.

CIRAS-DC

PP Systems CIRAS-DC dual channel infrared gas analyser

The CIRAS-DC is a dual channel, true differential infrared gas analyser featuring 4 independent gas analysers (2 for CO2 and 2 for H2O). The CIRAS-DC is capable of accurate, absolute measurement of CO2 and H2O in µmol -1 of two gas streams and displays the results as the absolute concentration of one gas stream (the reference) and the difference between the two gas streams. As such, it is capable of resolving small differences between two gas streams in real time.

This type of instrument (true differential analyser) is the preferred option for plant photosynthesis and respiration measurements where differential concentrations need to be resolved to a high degree of accuracy and precision.
