Porduct introduction ：
PPM-1 Plant photosynthetic meter can test CO2,air temperature,humidity,plant leaftemeprature,illumination,air flow etc parameters,
and then calculate plant photosyntheticratio,leaf evaporation,Stomata Conductance or CO2 sub stomata etc.
It widely used infields of Biology,Agriculture,Gardening,Forestry,Inset,Microorganism,Animal etc.
Measuring parameters ：
- The dispersive infrared CO2 analysis
- Leaf temperature
- PAR
- Leaf chamber temperature
- Leaf chamber moisture
Calculation ：
- Leaf photosynthetic rate(breathing)
- Leaf evaporation rate
- CO2 sub stomata
- Stomata conductance
- Efficiency of water application
Technical parameter ：
