Detailed Description
The TE525METS-L 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.

Additional Compatibility Information
Mounting
The TE525METS-L rain gage mounts to a CM300-series Mounting Pole or a user-supplied 1.5-in. 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.
Snowfall Adapter
The TE525METS-L is not designed for use with our CS705 rainfall adapter.
Wind Screen
Campbell Scientific offers the 260-953 Wind Screen to help minimize the effect of wind on the rain measurements. This wind screen consists of 32 leaves that hang freely and swing as the wind moves past them.
