As a more precise alternative to indicating silica gel bags, we supply a range of Humidity Indicator Cards (HICs). Above all, they change colour at specific Relative Humidity within a customer’s sealed product pack. Therefore, they are particularly useful for customers who sell diagnostic test kits, where a demonstration of the test kit’s efficacy is required upon pack-opening.
They are used by manufacturers of pharmaceutical chemicals, and are also included in bulk containers of moisture-sensitive chemicals, where they are used as an indicator of the container’s integrity.
Simply speaking, if you see that the HIC has changed colour, then you know that the packed-product is probably affected, and needs checking.
We provide 2 formats for the HICs:
- 1-Spot (with a single 8% indicator disc)
- 6-Spot (with indicator discs for: 10%, 20%, 30%, 40%, 50% and 60% RH on a single card)
