What is the term used for an open container that is utilized for measuring evaporation?

The term for an open container specifically designed for measuring the rate of evaporation is known as evaporation pans. These pans are typically shallow and filled with water, allowing for direct exposure to the atmosphere. Over time, the water levels in these pans decrease due to evaporation, and the rate at which this happens can be measured. This information is crucial for understanding water loss in various contexts, such as agriculture, landscaping, and environmental studies.

The other terms—evapotranspiration, water gauge, and humidity meter—refer to different concepts and tools. Evapotranspiration refers to the combined process of evaporation from the soil and plant transpiration, which is not limited to just measuring evaporation rates. A water gauge, often used for measuring rainfall, does not specifically track evaporation. A humidity meter measures the amount of moisture in the air but does not provide a direct measurement of evaporation rates. Thus, evaporation pans accurately encompass the function of measuring evaporation.
