Humidity indicators monitor humidity levels in enclosed spaces to prevent moisture damage. Available in different forms, including card indicators, electronic devices, mechanical indicators, and humidity plugs. They are all reversible and also come with the option without cobalt dichloride.

Electronic indicators are battery-operated and provide real-time monitoring of humidity levels. Humidity-indicating plugs are cost-effective alternatives with easy-to-read displays that change colour when humidity exceeds a certain threshold. The humidity indicators are available in relative humidity levels ranging from 5% to 95%, offering a clear visual representation of the humidity levels within the enclosed environment. The indicators can be paired with desiccants to protect assets from moisture damage.
