The Model 40A is a white PVC Rain and Sun
Guard for use with our probe style transmitters
such as Model 1205, 1235 and 1240. It is
designed to keep rain off the end of the probe
and prevent wetting of the sensor. It also
keeps direct sunlight from warming up the
sensors and thus providing a more accurate
reading of outdoor conditions.
The Model 40A is designed to accommodate a
4â€ probe length It differs from our original
Model 40 due to slightly larger opening to
accommodate the larger filter diameter found
in our newer Model 1205, 1235, and 1240 type
transmitters. The Model 40A features a screen
to prevent the entry and nesting of insects. See
