Unidata Evaporation Monitoring System
• The Evaporation Monitoring System measures how much water evaporates from a Class A evaporation pan by measuring the water level in an adjoining stillwell. The stillwell reduces fluctuations in the pan’s water level caused by wind.
• Fitted with a 100mm circumference pulley.
• Provides measurements with a resolution of 0.2mm.
• A thermistor probe float assembly rests on the surface of the water in the pan to obtain a surface temperature reading.
