Cobalt-free humidity indicator card, 5 % - 10 % - 60 % RH, pack of 125 - Warmbier 3785.0560.CF

Whether a moisture-proof pack stayed tight during transport and storage cannot be judged from the outside. The indicator card is packed together with the desiccant and shows across the range 5 % - 10 % - 60 % what climate prevails inside.

Advantages

• Cobalt-free version, it works without the cobalt(II) chloride used in classic indicator cards.
• Read off without instruments, the indicator spots change colour with the humidity.
• Measuring range 5 % - 10 % - 60 % relative humidity with two values in the dry range.
• Works together with the desiccant bags of the same supply range.
• Pack of 125 cards, sized for continuous series packing.

Application

The card is intended for Dry Shield packaging bags and other sealed moisture barrier packs holding moisture sensitive devices. On opening, the reading decides whether the assembly can go straight into production or has to be baked first. If the range between 10 % and 60 % has to be resolved more finely, the six-step version is the one to use.
