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 products, humidity indicator cards allow users along the supply chain to monitor the packages 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.
Features and Benefits

- Quickly measures humidity levels
- Can be vacuum sealed
- Cost effective
- Early identification prevents damaged items from entering production
- Identify and/or monitor humidity levels prior to opening inner contents
Applications
- Dry packaging of semiconductor and electronic devices
- Storing components in moisture barrier bags

Standard Indicator Cards
One Spot
Our one spot humidity indicator card is designed for use in desiccant containers to ensure the desiccant is in an activated condition.
Three Spot
The indicator spots on the HICs change color from blue to pink as humidity increases and from pink to blue as humidity decreases.
Four Spot
The indicator spots on the HICs change colour from blue to pink as humidity increases and from pink to blue as humidity decreases.
The indicator spots on the HICs change colour from blue to pink as humidity increases and from pink to blue as humidity decreases.

Maximum Humidity
Each level of relative humidity is representative by a blue crystal that dissolves to a large blue spot.
Cobalt Free
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 required.
Cobalt Free HI Cards provide humidity level indication for dry packaging to electronic and semiconductor manufacturers who desire a card without cobalt.
Three Spot Cobalt Free
Three spot indicator card, designed to be transported with heat-sealed moisture barrier bag.
Six Spot Cobalt Free
This card measures 6 spots from 10% – 60% humidity. Brown indicates dry.
Three Spot Cobalt
These cards are ideal for dry packaging of semiconductor and electronic devices.
Cobalt Dichloride Free
Cobalt-Dichloride Free Humidity Indicator (HI) Cards provide electronic and semiconductor manufacturers with a JEDEC-compliant humidity indicator card that is free of Cobalt-Dichloride, a chemical regulated under European Chemical Bureau (ECB) REACH directives.
Three Spot – Cobalt Dichloride Free
Three spot HIC indicates from blue to pink.
