product overview

The ET107 evapotranspiration monitoring station is an automated system developed by Campbell Company in the United States specifically for large-scale mechanized planting and irrigation. It can evaluate the water loss of soil due to evaporation and plant transpiration, calculate the evapotranspiration of crops, and provide scientific basis for crop irrigation water consumption. Users can easily read various monitoring data using the LoggerNet software, and automatically calculate evapotranspiration and other data through the software program, freeing users from complex calculations and greatly improving work efficiency.

A complete setThe ET107 evapotranspiration monitoring station includes various types of meteorological sensors, such as HMP50-ET temperature and humidity sensor, TE525ET rain bucket, 034B-ETM wind speed and direction sensor or WindSonic1-ETM two-dimensional ultrasonic wind speed sensor, CS305 net radiation sensor, etc., a set of CR1000M measurement and control module, a set of 3-meter aluminum bracket, and a 7Ah rechargeable battery. Users can use AC power or 10W solar panels to charge the battery. Monitoring data can be transmitted through telephone modems or shortwave wireless. In addition, users can also choose 107/108 soil temperature probes, CS616 soil moisture sensors, etc. according to their actual needs.

Measurement elements：radiation、air temperature、Relative humidity of air、rainfall、wind speed、wind direction、Soil temperature (optional)、Soil moisture (optional)
