Handheld Photosynthesis System (CI-340)

The CI-340 Handheld Photosynthesis System features a new design concept and compact solid-state structure. The entire system: the display, key pad, computer, data memory, CO₂ / H₂O gas analyzers, flow control system and battery are contained in a single, hand-held chassis. Everything required to measure photosynthesis, transpiration, stomatal conductance, PAR and internal CO₂ is conveniently included in one easy to operate instrument. Because the chamber is connected directly to the CO₂ / H₂O differential gas analyzers, there is virtually no delay when measuring CO₂ / H₂O in the chamber. These features make the CI-340 not only the smallest, but the fastest and most accurate Handheld Photosynthesis System available for field applications.

World’s lightest and most portable complete Photosynthesis System
Measures photosynthesis, transpiration, stomatal conductance, and internal CO₂ concentration in open or closed environments
Control heat, light, water and gas exchange for precise data
9 custom chambers suiting any application, including conifer needles
Soil Respiration Chamber available
