I. Instrument Introduction

Photosynthesis meter can measure gasCO2Concentration, air temperature and humidity, leaf temperature of the plants, light intensity, gas flow, and other factors, and calculate the photosynthesis of the plants.(Breath)Rate, Transpiration Rate, Inter-cellularCO2Four major photosynthesis indicators—concentration and pore conductivity—have extensive application prospects in many experimental courses across biology, agriculture, horticulture, forestry, entomology, microbiology, and animal studies.
