The humidity indicator works like a humidity indicator card, but can be screwed into the outer wall of the sealed container. They are made of aluminum, copper or steel and have large transparent viewing Windows to read humidity levels inside the container.Why use them?
Humidity sensitive goods are usually packed in containers that must not or cannot be opened before use.
