The TE525WS, manufactured by Texas Electronics, is a tipping-bucket rain gage that conforms to the National Weather Service recommendation for an 8 in. funnel orifice. It measures rainfall in 0.01 in. increments. This tipping bucket is compatible with all Campbell Scientific dataloggers, and it is widely used in environmental monitoring applications.Read More
The TE525WS funnels precipitation into a bucket mechanism that tips when filled to its calibrated level. A magnet attached to the tipping mechanism actuates a switch as the bucket tips. The momentary switch closure is counted by the pulse-counting circuitry of our data loggers.

Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.
The TE525WS rain gage mounts to a CM300-series Mounting Pole or a user-supplied 1.5” IPS pole. Several pedestal options are available to secure a CM300-series pole to the ground (see Ordering Information). Accurate measurements require the gage to be level.
The TE525WS is directly compatible with the CS705 Snowfall Conversion Adapter. The CS705 uses PG:E antifreeze to melt snow, allowing the TE525WS to measure the water content of snow.
Campbell Scientific offers the 260-953 Wind Screen to help minimize the affect of wind on the rain measurements. This wind screen consists of 32 leaves that hang freely and swing as the wind moves past them.
