Yaxin-1101s Photosynthesis Meter

Yaxin-1101s Pn Meter is specially designed for the teaching of plant physiology experiment in university. The instrument uses gas exchange method to measure leaf photosynthesis. The difference value of CO₂ concentration which leaf photosynthesis in chamber is measured, and then the photosynthetic rate of leaves is calculated.
I. Instrument Functions

1. Measurement function: Gas CO₂ concentration, humidity, temperature, leaf surface temperature, light intensity (PAR), gas flow rate

2. Calculation function: Photosynthetic (respiration) rate, transpiration rate, intercellular CO₂ concentration and stomatal conductance

3. Display function: CO₂ reference value/measured value; RH (relative humidity) reference value/measured value; Air temperature; Leaf surface temperature; Leaf area, flow rate and atmospheric pressure; Light intensity (PAR)

4. Software functions: Synchronous projection function; Manually controllable light source; Transmission software is free of installation; Support firmware upgrade through USB port; There are two measurement system: open system and closed system. Open system is preferred

5. Power supply function: Rechargeable battery; Low voltage alarm
