The RG-2500 tipping bucket rain gauge is a dependable instrument used for measuring precipitation. Rainfall that enters the 20 cm or 30 cm funnel collector is directed to the tipping bucket assembly. When an incremental amount of precipitation has been collected (0.254 mm), the bucket assembly tips and activates a magnetic reed switch.

The sample is discharged through the base of the gauge. A momentary electrical contact is provided for each increment of rainfall. The contact closure is used to operate a data acquisition system. The funnel has a screen to prevent debris from entering the gauge.

The Model RG-2500E is used where 115 Vac is available and precipitation is often in the form of snow. A 400 watt heater unit is installed on the base of the rain gauge. The outer tube is insulated and a freeze point thermostat controls the temperature at the funnel. Snow falling into the funnel is melted and the resulting water drains into the tipping bucket assembly.
