Wind Sensor
If there is any build-up of deposits on the unit, it should be gently cleaned with a
cloth, moistened with soft detergent. Solvents should not be used, and care should
be taken to avoid scratching any surfaces. The unit must be allowed to defrost
naturally after being exposed to snow or icy conditions, do NOT attempt to remove
ice or snow with a tool.
There are no moving parts or user-serviceable parts requiring routine maintenance.
Opening the unit or breaking the security seal will void the warranty and the
calibration.

HygroClip for Temperature, Humidity and Dewpoint
(Rotronic Model HC2-S3-GI)
For extreme environments such as maritime installations, chemical plants or other
areas of high pollution or contamination, Gill highly recommend replacement of the
temperature and humidity probe filter every 6 months to ensure proper
performance.
Corroded, discoloured or clogged dust filters should be replaced.
If the filter is not replaced it is very likely you will see elevated humidity levels with
time and if this is allowed to develop for a longer period of time it can lead to
permanent damage on the electronics of the temperature probe due to the very
high moisture content and corrosive effect of the pollutant or salt.
Rotronic Temperature and Humidity filter replacement:
The Rotronics polycarbonate dust filter screw-on cap is available from:-
Gill Instruments
Part Number
1723-PK-025 (2 filters).
Rotronic
Part Number
NSP-PCW-PE (1 filter).
If you need to replace the dust filter cap, carefully unscrew it and withdraw carefully
avoiding contact with the Temperature and Humidity circuit board. When re-fitting
the filter cap, ensure the circuit board connections are not bent.
Consideration should be given to an annual calibration check of the HygroClip
sensor by the manufacturer.
If you are replacing the whole cartridge, unscrew the metal ferrule and return the
probe to Rotronic for calibration. Refer to the Rotronic Website for more details:

NOTE.
If you return the sensor to a HygroClip supplier for exchange, please
request that the return unit has the dewpoint feature enabled (HCS2-S3
-GI
).
