Important Notes:
1. Do not touch the RH sensor with your hands.
2. The base of the sensor is made of alumina, thus it can easily break.
3. During the whole calibration cycle, operate at constant temperature as much as possible; nor-
mally, plastic materials have a poor heat conduction, thus they take some time before they reach
a thermal equilibrium.
4. In case you don't get satisfactory results, check that:
•
The sensor is neither faulty nor corroded
•
When calibrating, the measuring chamber is perfectly closed
•
Saturated solutions are not exhausted. A 33%RH saturated solution is exhausted when, in-
side it, between the two walls, there is no salt anymore, but only a thick liquid: in this case
the chamber cannot reach saturation anymore. For 75%RH saturated solutions, check that
the salt is not dry (crystallized): to reach saturation, it has to be damp.
5. Storage of saturated solutions: saturated solutions have to be possibly stored in the dark, at a
steady temperature of approx. 20°C, with the container perfectly closed and in a dry room.
