Humidity control cassettes from Prosorb present an easy way of maintaining a stable relative humidity level in display cases and cabinets.
Supplied as a complete unit, the prosorb cassettes require no additional containers or trays. Pre-filled with Prosorb beads, the cassettes are constructed from a sturdy polypropylene case with vapour permeable non-woven polyester panels.
Dependent upon the desired RH (relative humidity) '%' required, we have cassettes preconditioned to satisfy the ideal level for museum display cabinets, generally in the range of 40% to 60%. The enclosed Prosorb beads will absorb and desorb water vapour, as appropriate, to stabilise the humidity.
As with any other humidity control, it is important to monitor the environment using a hygrometer as reconditioning may be required after an extended period. Clay packs are available for reconditioning, see accessories below, for more details see here
