Yaxin-818 Photosynthesis Meter

This instrument is specially designed for photosynthesis experiment of middle school. It can quickly and quantitatively measure leaf photosynthesis or respiration. It can meet the need of The testing of leaf photosynthetic and respiration rates，curve Pn-par，effective of CO2 concentration and temperature to pn. The instrument can also be used in SMART projects, additional characteristic courses, laboratory and training of teacher skills.
