HUMIDITY INDICATOR CARDS
A Humidity Indicator Card (HICs) provide a low-cost method of indicating conditions inside a moisture barrier bag after vacuum packaging. The indicator spots on the HICs change colour from blue to pink as humidity increases and from pink to blue as humidity decreases. Indicates from 10% to 60% humidity. Can be used in conjunction with our moisture barrier bags.
The standard humidity card provides excellent protection and is designed for use with silica gel desiccants and moisture barrier bags. The indicator spots on the card change color based on the level being measured, offering clear visual feedback. These cards are made from moisture-sensitive blotting paper and are shipped in airtight containers to ensure they remain effective until use. Each tin contains 200 cards, and they comply with MIL-I-8835 standards for accuracy and reliability in humidity detection.
