Prosorb Humidity Control Cassettes

Prosorb Humidity control cassettes provide 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 vapor permeable non-woven polyester panels. Depending 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 vapor, as appropriate, to stabilize the humidity*. Price each.

*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.
