TE525 Tipping Bucket Rain Gage

5.1 Wind Screen

Campbell Scientific offers the 260-953 Wind Screen to help minimize the

effect of wind on rain measurements. This wind screen consists of 32 freely

hanging leaves that swing as wind moves past them. Refer to the 260-953

manual for siting information and the installation procedure.

5.2 Snowfall Adapter

Campbell Scientific’s CS705 Snowfall Conversion Adapter uses antifreeze to

melt snow, allowing the TE525WS to measure the water content of snow. The

CS705 cannot be used with either the TE525 or TE525MM. However, both

the TE525 and TE525MM can be converted to a TE525WS by returning them

to Campbell Scientific (see Assistance page at the beginning of this document).

Refer to the CS705 manual for siting information and the installation

procedure.
