INDICATION BEHAVIOUR
Ströbel HUMIDITY INDICATORS consist of special paper impregnated with different solutions. The paper changes the colour of the impregnated surfaces depending on the ambient air. If the humidity decreases again, the colouring changes in reverse order.

CORRECT PLACEMENT
Our humidity indicator cards are inserted into the packaging. It is not possible to check from the outside. If this is desired, moisture control windows must be used. These are screwed tightly into the barrier film and can be read from the outside.
HOW PRECISE
...are humidity indicators?
Their design is simple and inexpensive, therefore there is a permissible tolerance of +/- 5 % relative humidity. You cannot compare them in measurement accuracy with expensive electronic instruments.
If you want to take very accurate measurements and monitor many other parameters, we recommend our
