PP systems, UK; CIRAS – 2

The CIRAS-2 measures simultaneously both CO 2 and H2O through a differential system (reference and analysis). It features 4 independent, non-dispersive INFRA RED gas analyzers. The analyzers (reference and analysis) include an infrared source, highly polished, gold plated sample cells and detectors. The system is capable of providing independent, automatic control of CO2 and H2O to the leaf cuvette (reference) and within the leaf cuvette (analysis).
Control of CO2 and H2O can be dynamic allowing to carry out automatic response curve generation (e.g. assimilation rate vs CO2 concentration).
