CIRAS-4 is the portable system for measuring photosynthesis, chlorophyll fluorescence, soil respiration and CO2 fluxes from soil and foliage.


The CIRAS-4 was designed with the high-level field researcher in mind. Its small size makes it the most portable photosynthesis system of its kind, reducing the need for help or tripods.

The CIRAS-4’s innovative design takes advantage of the small system volume to ensure faster equilibration and the fastest and most accurate measurements available. Faster measurements allow the user to expand the parameters of his research and use his time and resources efficiently. Take a look at the size and weight of the CIRAS-4 console and tray cuvettes and you will quickly discover why smaller and lighter is better.
