WATER LEVEL SENSOR FOR EVAPORATION PANS
ET-250 is a highly accurate stainless steel submersible water level sensor used for Class A Evaporation pans to be connected to iMETOS stations. Highest precision is reached with Keller sensor technology, water temperature compensation and integrated barometric sensor module. Due to its innovative design, most mechanical Class A pans can be retrofitted with automatic ET measurements. It measures with 0.2 % accuracy.
