Humidity Indicators: Cobalt Free Humidity Indicator Cards

What are they?

Cobalt Free Humidity Indicator Cards provide humidity level indication for dry packaging to electronic and semiconductor manufacturers who desire a humidity indicator card without cobalt.

Why use them?

Many products are highly sensitive to moisture. In order to constantly verify that dry packaging methods are not compromised during storage and tansport 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 relavent 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.

The environmentally friendly Cobalt Free Humidity Indicator Cards do not contain cobalt and some configurations can be produced with less than 900 ppm halogen levels where reqired.

Cobalt Free Humidity Indicator Cards change color from brown to green when exposed to relevant humidity conditions.

Available configurations

Cobalt Free Humidity Indicator Cards are available in all standard configurations and humidity ranges, including indications at 5, 10 and 60 percent relative humidity levels.
