QT-1010 Automatic Microclimate Measurement System

Product Details

QT-1010 automatic microclimate measurement system is used for automatic monitoring of ten weather elements such as wind direction, wind speed, rainfall, air temperature, relative humidity, air pressure, solar radiation, photosynthetically active radiation, soil temperature, and soil humidity. Other measurement elements can be customized according to user needs, such as evaporation, hours of sunlight, photosynthetically active radiation, soil heat flux, net radiation, etc. The measurement height is generally 2-6 meters, which varies according to the height difference of vegetation. The farmland microclimate station provides good support for agricultural scientific research, agricultural production, and animal husbandry.

The formation of ecological microclimate is based on the local topography and macroclimate. At the same time, the characteristics of microclimate change with the type, variety, growth period and growth status of crops, resulting from the interaction of the atmosphere, soil and crops. In long-term ecosystem monitoring, monitoring of meteorological factors is necessary. Air temperature, precipitation, humidity, sunshine, wind direction, and wind speed are important ecological factors, as well as important factors affecting plant growth and development. These factors not only have characteristics of daily change, monthly change, seasonal change, but also annual changes. It is of great significance to carry out long-term monitoring of these meteorological factors, summarize their changing laws, and seek their relationship with plant growth.
