±.25% F.S. (Grade 3A)*

 

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.
