Plant Photosynthesis Meter

Application

The equipment is specially designed for plant physiology experiment teaching, and can also meet the undergraduate course teaching and advanced plant physiology experiment course, significantly improve the teaching quality of theory and experiment.In biology, the agronomy, horticulture, forestry, insects, microorganisms, animals, and many other professional experiments course have wide prospect of use.
The instrument can be used to measure the gas concentration of CO2, air temperature and humidity, plant leaf temperature, light intensity, gas flow rate, etc.

Features:

1. The measurement functions
• measuring CO2 concentration in the air, humidity, temperature, leaf temperature
• measurement in the gas flow in the gas path
With open and closed two measuring ways
2. Computing functions automatically calculate the following parameters:
• photosynthetic rate (breathing)
Leaf transpiration rate
• intercellular CO2 concentration
Stomatal conductance,
3. The display
The CO2 density, air temperature, humidity, air temperature, leaf
• timing display
The photon flux density values
4. Storage transmission function
• can be stored and data transmission used in the measurement and calculation
5. Mobile capabilities
Desktop and portable
6. Power supply function
The ac power adapter or rechargeable battery
• low voltage alarm
