详细信息
Yaxin-818 Pn meter
This instrument is specially designed for photosynthesis experiment of middle school. It can quickly and quantitatively measure leaf photosynthesis or respiration.
Ⅰ、 Features
patented products
digital sensors
intelligent control of environment
projection in classroom
colorful screen
Ⅱ、 Application
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.
Ⅲ、 Principle
The change value of CO2 concentration in the closed chamber was measured within a certain time, and then the photosynthetic rate of leaves was calculated.
