480 1000 121/01 Rain Sensor Description
Replacement Rain Sensor for use with the Atmos Dual, Climatica Dual, Climatica Plus and EWS Weather Stations.

The Rain Sensor comes pre wired with 25m of cable.

The rain sensor should, ideally, be situated at a distance of twice the height of local obstructions and mounted 30cm (12”) above ground level. This requirement can often be difficult or impossible to achieve due to surrounding bushes, tress etc. For most practical purposes accuracy will not be greatly impaired if the site is only a distance equal to the height of the obstructions.

It is important that the sensor is reasonably accessible as, from time to time, the filter will require cleaning. Very often the top of a fence post provides an excellent site so long as it is firm, clear of bushes and trees above.

It is wise to avoid mounting on or near buildings which can cause wind turbulence and create dust. 
Avoid also mounting near to transmitter aerials which can certain circumstances cause interference.

480 1000 121/01 Rain Sensor MAINTENANCE & TROUBLESHOOTING
The Instromet Rain Gauge will provide superb performance and super sensitivity with a resolution of only 0.01 mm. Unfortunately this sensitivity comes at a small price – the need for regular cleaning of the funnel and filters. The frequency of this cleansing will to a large extent depend on the locality of the site. In very dusty areas, in times of predominantly dry weather, the gauge may well have to be cleaned once a month whereas cleaner areas may only require attention twice a year.
