Portable Plant Photosynthesis Tester

Product Details

Features:

This Portable Plant photosynthesis tester is to observe and measure the photosynthesis and transpiration of a plant leaf on or off the stem

Open or closed way for measure of the rate of photosynthesis

To calculate the rate of photosynthesis (respiration) and transpiration, stomata conductance or internal CO2 concentration by appropriate formula

All stored data transmitted to a computer.

Easy to take for use indoors and outdoors.
