255-100 Analog Output Evaporation Gauge Campbell Scientific

 

Evaporation gauges determine the evaporation rate by measuring the changing water level in an evaporation pan. The gauges consist of a float, pulley, and counterweight attached to a potentiometer mounted through a gear assembly in weatherproof housing. The evaporation gauges produce a resistance output that data loggers can measure.

Overview


The 255-100, manufactured by Novalynx, determines evaporation rate by measuring the changing water level in your evaporation pan.
