Integra Boost humidity indicator cards give an easy, reliable way to check the humidity level of a storage space at a glance. The cards show relative humidity clearly through colour changes, so monitoring conditions is effortless without separate measuring devices.

The indicator dots change colour in response to the surrounding humidity, helping you judge whether the storage space is too dry or more humid than the target level. This makes the cards a good companion to humidity control packs such as Integra Boost.

The compact size suits a range of storage solutions, such as jars, boxes and other airtight containers. The cards work for everyday use as well as closer monitoring of storage conditions.

Key features:

• Clear visual humidity monitoring
• Several humidity levels (10% - 60%)
• No batteries or maintenance needed
• Suitable for use with humidity control packs
• Compact and easy to use

The pack contains 10 humidity indicator cards.

A practical solution for keeping storage conditions even and controlled.
