The 255-200 Evaporation Pan is a standard National Weather Service Class A type for measurement of water evaporation. It is normally installed on a wooden platform set on the ground in a grassy location. The pan is filled with water and exposed to represent an open body of water. The pan is filled to within 2.5 inches of the top of the pan. The evaporation rate can be measured by manual readings or with an analog output evaporation gauge.

The 255-100 Analog Output Evaporation Gauge is used to determine the evaporation rate by measuring the changing water level in an evaporation pan. The sensor consists of a float, pulley, and counterweight attached to a precision 1000-ohm potentiometer mounted in a weatherproof housing. The potentiometer produces a resistance output proportional to the position of the float which can be monitored on site using a data logger or remotely by telemetry equipment. A standard National Weather Service Class A Evaporation Pan is recommended for use with the gauge. The NovaLynx 255-200 Class A Evaporation Pan is designed to be coupled to the gauge by means of stainless steel connecting pipes and fittings.
