Typically used in hyperbaric chambers, decompression chambers and the like. Perma-Cal® caisson gauges incorporate a Bourdon tube sealed within a capsule. Unlike standard pressure gauges which indicate the pressure relative to the ambient environment, Caisson gauges indicate the pressure relative to the pressure within the capsule.
