Humidity indicators can vary from a simple colour change paper right through to a state-of-the-art electronic polymer sensors. Desiccant solutions can advise on the best options available for most applications.
A colour change indicator card is a great way to track the effectiveness of desiccation within a sealed container or equipment at a relatively low cost. We can supply stand alone cards right through to complex housings which allow for internal monitoring without the need to open the enclosure.
REACH compliance is a very important consideration for many customers. However, the most used chemistry in indicator cards today is not REACH compliant. These Indicators contain Cobalt Dichloride which is listed on the current (2021) Substances of Very High Concern (SVHC) list.
We can offer alternative chemistry papers which allow for REACH compliance to be achieved. These include Cobalt Dichloride Free & Cobalt Free chemistries.
