Purpose:When spraying agricultural chemicals on crops, it is crucial to ensure their safety and effectiveness by measuring the relative humidity, wind speed, and direction of the air. Many places have stipulated the maximum wind speed for agricultural chemical spraying, in order to minimize the drift of agricultural chemical spraying. Under hot and dry conditions, agricultural chemicals may evaporate into the air instead of onto your crops. However, you can reduce this evaporation by selecting an appropriate nozzle and increasing the size of the spray droplets.
The Kestrel 3500DT agricultural handheld meteorological instrument integrates Delta T calculation, which can quickly provide ideal agricultural chemical spraying environment values based on wet bulb temperature and dry bulb temperature. For example, it is not recommended to spray agricultural chemicals above a Delta T value of 10, and a value of 2-8 is the ideal range for agricultural chemical spraying.
The wet bulb temperature calculation of Kestrel 3500DT agricultural handheld meteorological instrument adopts pressure calibration to ensure accuracy in low-pressure environments. Delta T monitoring is very important in high-altitude areas and dry environments.
