Rk300-04 Online 4-20mA Leaf Wetness Duration Sensor for Fruit Cultivation
Product Description
RK300-04 Leaf Wetness Sensor is an important tool for observing and studying leaf wetness, preventing pests and diseases, and spraying sprinkler control. The accurate measurement of the moisture content of the leaf surface can be used to monitor the trace moisture or ice crystal residue. The shape of the sensor is simulated by the blade, which can simulate the characteristics of the leaf surface, so that it can reflect the situation of the leaf surface more accurately. By measuring the variation of the dielectric constant of the upper surface of the blade, the mist, water vapor and ice can be measured.

MOUTING
When installing the sensor to simulate the face of the grid part of the face, roughly the same angle with the surrounding surface and the ground. Such as foliar fertilization spray testing, can be installed in the plant height of different height, to ensure that the plant close to the ground effect of foliar fertilization.
