Antistat 309-0072 Humidity Indicator Card 6 Spot 10-60% Colbalt Dichloride Free

Humidity Indicator Cards (HICs) provide a low-cost method of indicating humidity conditions inside a moisture barrier bag after vacuum packaging.

The indicator spots on the HICs change colour as the humidity increases and decreases. In order to constantly verify that dry packaging methods are not compromised during storage and transport of these products, humidity indicator cards allow users along the supply chain to monitor the package conditions. Indicator spots change from brown to green after exposure to the relevant relative humidity conditions.

The cards are reversible and change as conditions change in the packaging environment, allowing users to monitor the conditions of product packaging.
