The DryCard is low cost humidity indicator that change colour in response to relative humidity card for monitoring relative humidity (RH).  The reusable indicator paper can measure the RH of ambient air or of the inside of a container.  For simply monitoring storage suitability, no conversion is necessary, as the colour of the indicator paper can be related directly to the potential storability of the commodity, as shown on the DryCard.

By enclosing a DryCard inside of a moisture-proof container containing a sample of the commodity or embedding it in the commodity mass quickly estimates the effective relative humidity (ERH) and therefore the risk for mycotoxin accumulation or insect damage.

This is a very inexpensive and convenient way to estimate the ERH of the product in the field during drying or in storage.
