The soil evapotranspiration meter is a more systematic and comprehensive standard experimental equipment developed and produced by our company based on the continuous development of modern electronic technology, soil physics, microclimate and other disciplines to measure transpiration and evaporation in farmland and groundwater soil water conversion. The instrument adopts a good high-resolution weighing system, equipped with an intelligent data collector and signal sensor, which can simultaneously detect the small changes in soil moisture transpiration, evaporation, leakage over time, as well as corresponding parameters such as temperature, air humidity, light, precipitation, etc. The measured data is analyzed, processed, recorded and stored in real-time online, achieving high data collection efficiency
