Humidity Indicator Plugs allow users to monitor humidity levels inside a sealed packaging without having to open it.
Usually made of aluminum, brass or stainless steel, these plugs are mounted on the sealed container like a window fitted with an humidity indicator card. By the help of the humidity indicator card, the plug enables visual indication of humidity level inside the sealed packaging.
Desiccator Plugs both indicate and control humidity levels inside the sealed container. In this application, a desiccant tube extends from the indicator into the container. They are usually designed for small containers where space is limited.
Why use it ?
Delicate goods are often carried/stored in sealed containers which should not or can not be opened until use.
By the help of Humidity Indicator Plug installed on the walls of the container, users can easily check humidity levels and can ensure that the goods inside are kept in safe humidity levels. As the container is not opened, this check is carried out without goods being exposed to external affects.
Humidity indicator and desiccator plugs are available in a variety of sizes and configurations so as to respond to requirements of various packaging applications.
