At Cannadew, precision meets clarity

Our Humidity Indicator Cards are crafted from high-grade printed substrates coated with a cobalt chloride–based color-changing solution that shifts from blue (dry) to pink (humid). Each card is carefully calibrated to monitor humidity from 10% to 90% RH, giving you an instant and reliable visual reference of your storage environment.

Trusted by professionals and enthusiasts alike, these indicators are perfect for cannabis jars, curing bags, cigar humidors, food packaging, electronics, and pharmaceuticals—anywhere precise humidity awareness matters.

⚠️ Note: The indicator card should not come into direct contact with food or consumable products.
