CIRAS-4
CIRAS-4 Portable Photosynthesis System
The CIRAS-4 is a 4th-generation portable photosynthesis system designed for plant gas exchange research. Its dual-beam infrastructure, offering both differential and single-channel modes, delivers high accuracy. By simultaneously measuring CO₂ and H₂O exchange, it calculates net photosynthesis, transpiration and stomatal conductance. Its smart leaf cuvette and automatic zeroing system greatly simplify field work.
