Indicating Silica Gel Packets:

 Dry-Packs® brand Indicating Silica Gel is packaged in a clear perforated (breathable) plastic packet. Our Cobalt Chloride FREE indicating Silica Gel beads will turn from Orange to Dark Green when the Silica Gel is about 60% absorbed with moisture. We do not recommend reactivation of these packets as they could melt during reactivation.Humidity Indicator Cards: We offer two types of Dry-Packs® Humidity Indicator Cards; the Blue to Pink humidity indicator cards and the new Cobalt Chloride Free humidity indicator cards that turn from Brown to Pale Green. Both types of cards have two choices, either the 3 dot (30-50% humidity) or 6 dot (10-60% humidity) humidity gauge.
