Plant Photosynthesis Meter
Plant Photosynthesis Meter
Product description about Plant Photosynthesis Meter:
NY-1020 photosynthesis instrument can measure the gas CO2 concentration, air temperature and humidity, plant leaf temperature, light intensity, gas flow and other factors, and calculate the plant photosynthesis (respiration) rate, transpiration rate, intercellular CO2 concentration and stomatal conductance. Photosynthesis indicators have broad application prospects in many professional experimental courses such as biology, agriculture, horticulture, forestry, insects, microorganisms, and animals.
Measurement items:
*Non - diffusion infrared CO2 analysis
*Leaf temperature
