The tipping bucket rain gauges 52202 and 52203 meet the specifications of the World Meteorological Organization (WMO).
The design uses a proven tipping bucket mechanism for simple and effective rainfall measurement. The bucket geometry and material are specially selected for maximum water release, thereby reducing contamination and errors.
Catchment area of 200 cm2
and measurement resolution of 0.1 mm meet the recommendations of the WMO. Leveling screws and bullseye level are built in for easy and precise adjustment in the field. Measured precipitation is discharged through a collection tube for verification of total rainfall.
Model 52202 is heated for operation in cold temperatures. An unheated version, 52203, is available for use in moderate climates. To discourage birds from perching on the funnel rim, accessory bird wire assembly may be attached to the gauge.
