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 BFS 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 BFS 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 Workabout

The Workabout is dust proof and splash proof (IP54), and has a 1 metre drop test

rating, but does not contain desiccant. Operating conditions are specified as 0% -

90% RH, non condensing.

Warning! If you leave the Workabout in the field for Autologging, you must enclose

it in a bag or container with plenty of desiccant to protect it from the possibility of

internal condensation.
