Evaporator and implementation method thereof

The invention discloses an evaporator and an implementation method thereof. The evaporator mainly solves the problems that in the prior art, water level measurement adopted for water surface evaporation measurement is low in precision, high in labor cost and the like. The evaporator is characterized by comprising an evaporation pan (2), a weighing system and a motion actuating mechanism; when the evaporation pan is placed on the weighing system, the weighing system weighs the evaporation pan, and the evaporation pan (2) can break away from and placed on the weighing system through the motion actuating mechanism. The evaporator is simple in structure, convenient to implement and high in measurement precision.
