Humidity Indicator Cards

Monitor humidity levels and protect moisture-sensitive components

Humidity indicator cards (HICs) provide a simple, low-cost way to monitor humidity conditions inside moisture barrier bags and sealed packaging. Each card features indicator spots that change colour as humidity rises or falls, offering a quick visual check of internal conditions.

Early identification helps prevent damage by revealing when items have been exposed to moisture before entering production or inspection. Choose from cobalt dichloride-free humidity indicator cards or humidity indicator bulk tins of 200 cards for consistent, compliant monitoring across your packaging process.
