Minimal Size. Maximum Performance.
The CIRAS-4 is designed with the high-level field researcher in mind. Its small size makes it the most portable photosynthesis system of its kind, alleviating the need for assistance or tripods.
The innovative design of the CIRAS-4 utilizes its small system volume to ensure faster equilibration as well as the most rapid and accurate measurements available. Faster measurements allow the user to expand the parameters of their research and use their time and resources efficiently. Check out the size and weight of the CIRAS-4 console and leaf cuvettes and you will quickly discover why smaller and lighter is better.
Fast response. Fully mobile.
The location of the CIRAS-4’s IRGAs (Infrared Gas Analyzers) in the main console — right next to the internal gas mixing system and flow control — allows the CIRAS-4 to provide an ultra-fast response to changes in “reference” gas, and the fastest and most accurate portable photosynthesis measurement available. IRGAs in the console makes the entire system highly portable, not to mention the added protection from dirt, dust, and debris commonly found in and around a leaf cuvette.
True differential analyzer for the ultimate accuracy & reliability.
The heart and soul of any photosynthesis system is the analyzer. Accurate, reliable, and stable measurement and control of CO2 and H2O are critical for high-level research. A “true differential analyzer”, the CIRAS-4 features 4 independent, non-dispersive gas analyzers for accurate, simultaneous measurement and control of both CO2 and H2O — a significant advantage over “gas switching” systems and a major requirement for most researchers. The analyzers act as absorptiometers measuring infrared absorption only. The temperature-controlled optical bench is pressure compensated ensuring the most accurate measurement of CO2 and H2O under changing ambient conditions.
