50-90% Maximum & Reversible Humidity Indicator Card
The MXC56789 Maximum Humidity Indicator Card was designed for applications which require monitoring the maximum humidity attained when exposed for a period of 24 hours or more. Each level of humidity indicated on these cards is represented by a blue crystal which dissolves when the relavtive humidity (RH) level exceeds the humidity shown below it. When the crystals dissolve, they create a large blue spot above the indicated humidity.
Example: If the highest humidity level reached is 70% RH, then all circles up to and including 70% will have dissolved crystals and the area surrounding each circle will be stained blue.
