Humidity indicator cards are small, paper instruments designed to provide visual proof of the relative humidity levels within a given environment. These 6 spot cards are reversible and constantly keep track of humidity levels as low as 10% and as high as 60%, changing colour from blue when it’s dry, to pink when it’s humid.
If the card indicates high levels of humidity, users know to check their packaging and inspect their products in case of damage – a great and inexpensive way to assist you in keeping your valuables protected.
