Leaf temperature difference measuring instrumentPurpose:：

The water status of plants directly reflects their growth, and measuring the water content of plants can achieve precise irrigation in agriculture, which is the only way to achieve water-saving irrigation today. Research has shown that leaf air temperature difference (the difference between leaf surface temperature and air temperature) can effectively reflect the water balance of plants. In addition, there have been many studies on the impact of environmental temperature on important growth processes such as plant flowering. To further reveal the coupling mechanism between plants themselves and environmental temperature, it is necessary to measure the "body temperature" of plants. At present, infrared thermometry is widely used to measure leaf temperature, but it is difficult to determine leaf reflectance due to physiological changes inside the leaves; At the same time, the environment has a significant impact on the infrared temperature measurement method, resulting in large measurement errors that cannot meet the accuracy requirements. Our company has developed a blade temperature difference measuring instrument that uses imported high-precision surface mount platinum resistance temperature sensors for contact measurement of blade temperature,Leaf temperature difference measuring instrumentThe instrument is capable of real-time and accurate measurement of leaf temperature and temperature difference through live collection of leaf temperature. It has the characteristics of reasonable structure, simple operation, and large data storage capacity.
