The hygrometer is a sensitive piece of equipment. Please do not touch it, except to recalibrate the dial, otherwise you risk damaging it. Please do not expose to direct heat or intense sunlight.
As the hygrocase is fairly airtight (we do not want it to be absolutely airtight) it should be opened regularly, at least every few days, for an hour, to allow air to circulate around your reeds. The inside of the case should be cleaned occasionally with a damp cloth. When cleaning the outside, please use an anti-static cloth.
Notice for oboe model: Please do not use oboe reeds with full metal staples. These are often too heavy to ensure a secure hold, especially if several are kept in the case.
Caution: Do not use cleaners containing solvents.
When using your hygrocase, check that the dial hand is always within the NORMAL range of humidity (between 40-70).
If the dial hand is lower than NORMAL, the sponge needs to be wetter and if it is higher than NORMAL, the case should be opened to let the sponge dry out a little. Placing a reed back in the case after use will also increase the humidity level.
With the air vent closed your reeds are protected against changes in the surrounding environment.
The vent can be easily rotated according to your needs, allowing for more or less airflow as needed.
Opening the vent completely allows the reeds to dry out and acclimate to the surrounding climate.
Should the hygrometer require calibration, we recommend the following steps:
Soak a towel in lukewarm water. Remove all the reeds from your hygrocase and wrap the case in the towel. Place this combination on your heater or in direct sunlight and wait for at least an hour.
After about an hour the hygrometer should read 100% humidity. If this is not the case, the hygrometer can be rotated until the dial reads 100%. After this process the hygrometer is calibrated and you can continue using your hygrocase.
Should your Hygrometer need to be exchanged, this can easily be done as depicted below.
