Humidity indicator cards provide a simple and reliable visual indication of the relative humidity inside sealed packaging and other enclosed environments. These chemically treated cards change colour at specific humidity levels, making them ideal for monitoring moisture-sensitive products and verifying the effectiveness of desiccants and moisture barrier packaging.

Inkbird wireless hygrometers allow you to remotely monitor temperature and humidity using the free iOS and Android app. They are ideal for monitoring wardrobes, pet enclosures, musical instruments, food storage, vehicles and other humidity-sensitive environments.
