Overview
The 52202, manufactured by R. M. Young, is a thermostat-controlled, electrically heated, tipping bucket rain gage. You can use it to measure rain, snow, and other frozen precipitation. Its catchment area of 200 cm2 and measurement resolution of 0.1 mm meet the recommendations of the WMO. This heated rain gage is compatible with most Campbell Scientific data loggers, and it is used in environmental monitoring applications.
Key Advantages
Thermostat-controlled gage
Technical Description
The 52202 funnels precipitation into a bucket mechanism that tips when filled to the calibrated level. Each tip is marked by a magnetic reed switch closure that is recorded by a Campbell Scientific data logger pulse count channel.
The 52202 has a thermostat-controlled internal heater that melts snow or other frozen precipitation. This heater requires a reliable source of 24 Vac power. A wall transformer is shipped with the 52202 that plugs into a wall socket to provide the required 24 Vac power.
Benefits
- High precision—tips at 0.1-mm increments
- Heating element melts snow and ice for year-round measurements
- Compatible with many Campbell Scientific data loggers

Common Accessories
(4)CM221
Right-Angle Mounting Kit
The CM221 mounts a pipe or tube at 90° to another pipe or tube. It is typically used to attach a sensor with a vertical pipe (including most wind sensors) to a crossarm. The cast aluminum, right-angle mounting bracket has 3.8 cm (1.5 in.) U-bolts and hardware and will accommodate tubing with a 1- to 1.5-in. outer diameter.

DIN Rail Terminal Kit with 3 Terminals and 5 Wires
This kit is typically used for power supplies, smaller solar panels, or other power sources. It provides the needed DIN rail terminals, separator, and wires to connect any product to a data logger or other peripheral that requires five wires for connection. This kit provides the following wires: 22 AWG black, 22 AWG white, 22 AWG clear, 16 AWG black, and 16 AWG red. The color-coding of these wires matches the wire coloring of the product for ease in connection, maintenance, and troubleshooting.
