1、 Product Description

Field microclimate automatic observation instrument, used for all-weather on-site monitoring of meteorological elements such as wind speed, wind direction, rainfall, air temperature, air humidity, light intensity, soil temperature, soil humidity, evaporation, atmospheric pressure, etc. It can be connected to a computer through a professional data collection communication cable, and the data can be transmitted to the meteorological database of the meteorological computer for statistical analysis and processing. Mainly used in meteorology, agriculture, geology, environment and other fields, and suitable for field scientific research and experimental applications.

2、 Performance characteristics

1. The microclimate automatic observation instrument consists of meteorological sensors, meteorological data recorders, power systems, field protection boxes, and stainless steel brackets.

2. Sensors such as wind speed, wind direction, rainfall, and evaporation are specialized meteorological sensors with high precision and reliability.

3. The meteorological data recorder has functions such as meteorological data collection, scheduled storage of meteorological data, parameter setting, user-friendly software human-machine interface, and standard communication. The graphical data display can be operated through wired communication in a Windows 2000 or above system environment, and the data storage format is EXCEL standard format. It can generate meteorological data charts for other software to call.

4. Wired transmission method: Through a standard USB communication interface, it is wired to the monitoring center PC for real-time transmission of collected data.
