Environmental and moisture protection
You should be aware of the different levels of protection of the
components of the SunScan system to avoid putting them at risk when
working outdoors. As with all field instruments you should minimise, as far
as practical their exposure to high or rapidly changing temperatures.
The SunScan probe and Beam Fraction Sensor
Warning! The probe and BF5 are designed to resist dust and water jets
(IP65), but they are not hermetically sealed. They will survive rainfall, but
will not survive being immersed in water.
Avoid any situation where they could be flooded. Internal condensation
will be avoided provided that you keep the desiccant fresh. Inspect the
coloured indicator panels on the housings to check this.
The probe and BF5 are reasonably robust, but they do not have a drop
test rating. Do not drop them! Take extra care when carrying the 1 metre-
long probe!
The PDA
The PDA is extremely rugged, sealed to IP67, that is sealed against
accidental immersion (submersible to 1 meter for 30 minutes).
For details see the impressive environmental specifications listed in the
Getting Started Guide.
The weakest link may be the 9 pin serial connector on the SunScan cable,
which is not sealed .
Warning! If you leave the PDA in the field for Autologging, we recommend
you seal it in a bag or container with, say, 25g of desiccant (to protect the
SunScan serial connector from moisture).
