Product Description
This humidity indicator card from DESCO, 6HIC200, is a 6-spot humidity indicator card for visual monitoring of relative humidity. The card contains six moisture-sensitive spots that change color in response to humidity levels, and it comes in standard packaging of 200 cards per can. The 6HIC200 is manufactured in the USA and complies with the specified military standards indicated by the manufacturer.
Function and Construction
The moisture-sensitive spots are made of blotting paper impregnated with cobaltous chloride, which provides a visible color change from blue to pink when exposed to moisture. The card specifically indicates relative humidity at 10%, 20%, 30%, 40%, 50%, and 60%.
Documentation
Official technical documentation can be found in the manufacturer's datasheet, which includes specifications for material, measurement points, packaging size, and standard compliance.
Typical Applications
- Monitoring humidity inside dry-packed barriers by including an HIC card inside each bag and inspecting the card upon opening.
- Use in dry packaging contexts where visual control of relative humidity in the packaging is desired.
