Control Company announces its new Traceable Humidity-On-A-Card. The cards monitor humidity levels in shipments, optics, and packaging and are ideal for use with bottles, chemicals, plastic bags, electronics, desiccators, and storage containers. 

Color changes from blue to lavender in increments of 10% RH. A reversible indicator changes color as the humidity increases and decreases. The cards are readable to an accuracy of ±5%RH at 75°F (24°C).

Maximum relative humidity attained is indicated by the highest numbered hole containing dissolved crystals, which will cause the paper around the hole to turn blue. Once dissolved, the reading will not change. Each card is individually sealed in a clear moisture-barrier bag with a Humidity Sponge desiccant to keep the card dry and provide for an extended shelf life. Card size is 4 x 4 inches.
