Important notes:
1) Do not let hands touch the RH sensor.
2) The sensor base is in alumina so it could easily break
3) Storage of the saturated solutions: The saturated solutions must be stored in a dark environment
at a constant temperature of about 20°C with the container well closed inside a dry room.
