Plant Transpiration Rate Meter​ introduction:
The plant transpiration rate meter HLY-ZT1 is mainly used to measure parameters such as plant transpiration rate, stomatal conductance, leaf temperature, photosynthetic effective radiation, temperature, and humidity. Plant transpiration can promote the transportation of substances in xylem sap, and mineral salts in soil and substances synthesized by roots can be transported and distributed to various parts of the plant body with the absorption and concentration of water; Transpiration can also lower the temperature of plant bodies and prevent leaf burns, as water has a high heat of vaporization and can dissipate a large amount of radiant heat during transpiration. The normal process of transpiration is conducive to the assimilation of CO2, because during leaf transpiration, stomata are open, and the open stomata become channels for CO2 to enter the leaves. Therefore, stomatal conductance is also of great significance for plant transpiration rate and photosynthetic rate. The measurement of plant transpiration rate and stomatal conductance is of great significance for agricultural research, teaching, horticultural research, forestry research, and more.
 
Plant Transpiration Rate Meter Features:
1. Multiple indicators: can simultaneously measure air temperature, leaf temperature, air humidity, photosynthetic effective radiation intensity and other indicators, and use this to calculate plant transpiration rate and stomatal conductance;
2. Intelligence: Multi information Chinese menu display and cursor guided operation, instantly displaying and storing the measurement process and final results on the screen. Small in size, light in weight, portable and operated by one person;
3. Widely applicable: equipped with different types of leaf chambers, it can be widely used for measuring different shaped leaves of various plants such as field crops, fruit trees, vegetables, and forage;
4. High cost-effectiveness: low price, low usage cost, and convenient maintenance.
