INTEGRA Humidity Indicator Cards 10pk - 10-60% RH

Instant Visual Humidity Readings for Sealed Storage, 10-60% RH

Confirming humidity levels inside a sealed container usually means opening it and disturbing the very conditions you are trying to check. Integra Humidity Indicator Cards solve that with a no-tool visual reading across a 10% to 60% RH range, using indicator dots that turn bright blue once humidity crosses a specific threshold.

Each compact card fits inside jars, bags, and totes without taking up meaningful space, and the 10-pack provides monitoring capacity across multiple containers in a single storage operation.

Key Features & Benefits

• 10-60% RH range — covers dry storage through optimal curing humidity in one card format.
• Visual indicator dots — turn bright blue at specific RH thresholds for instant confirmation without meters or probes.
• Compact card format — fits inside jars, bags, and totes without interfering with stored product.
• 10-pack quantity — monitors multiple containers across a storage operation at a low per-card cost.
• Pairs with Integra Boost packs — confirms a humidity control pack is still active without opening the container.

Who Should Use This

Anyone using sealed containers for curing or long-term product storage who wants a fast visual humidity check without opening containers or using separate measuring equipment is the direct fit for these cards.

Frequently Asked Questions

How do the indicator cards work?

The cards contain chemical indicator dots that react to ambient relative humidity. Each dot is calibrated to a specific RH level and turns bright blue once the humidity in the container reaches that threshold.

What is the RH reading range?

Each card reads relative humidity from 10% to 60%, covering the full range from very dry to optimal curing humidity. That span lets one card format work across most sealed-storage use cases.

How long do the cards remain accurate?

Accuracy depends on storage conditions and usage, and readings may gradually drift with repeated exposure to high humidity. Replace cards if readings appear inconsistent with measured conditions.

Can these cards monitor Integra Boost pack performance?

Yes, placing a card alongside an Integra Boost pack in a sealed container lets you visually confirm the pack is maintaining its target RH. This avoids opening the container just to check whether the Boost pack is still active.
