Propasecard is a stiff card with reversible moisture indicator “without cobalt” for checking the level of relative humidity.
The moisture indicator must be positioned inside the packing of the product to be protected.
Available in a number of configurations, Propasecard can indicate low relative humidity levels down to a RH of 5% or high levels up to a RH of 95%, according to the application and necessity.
Propasecard provides visual proof of the level of RH in an environment and/or packing. If Propasecard indicates high levels of humidity, users know that the desiccant must be replaced (if necessary) and the product checked. It is usually used with desiccants in any application in which humidity is at a critical point.
Propasecard helps to provide better protection and control of your products from possible damage caused by humidity. Humidity can modify, change or destroy the properties of your product.
Easy to use and lightweight, it allows the state of your products to be rapidly checked. The quality, stability and properties of the product can thus be easily kept under control.
When activated, the moisture indicator is yellow (no humidity) and turns green as the humidity level increases.
Indicators with viewing window: Useful for checking the relative humidity inside a container from outside the container itself.
