Perma-Cal 6" Caisson Gauge | Direct Drive Pressure Instrument | Made in USA
Part Number: 200FTM79Y01
Dial Size: 6"
Pressure Range: 0-1000 FSW (Feet Sea Water)
Accuracy: ±0.25% asc / ±0.5% des
Pointer Type: Test (knife-edge precision)
Case Type: Front Flange
Case Color: Yellow
Connection: 1/4" NPT (Rear position)
Dial Features: Mirror Band + Pointer Dampening + External Zero Adjust
Caisson Gauges measure pressure inside hyperbaric chambers, decompression chambers, and submarine atmospheres. Unlike standard pressure gauges that read pressure relative to ambient, Caisson Gauges read pressure relative to the capsule interior. Calibrated in Feet of Sea Water (FSW) for direct diving / hyperbaric correlation.
One moving part—helically-wound Bourdon tube design
Inconel X-750 wetted parts with low coefficient of thermal expansion
316 SS standard connection material (Monel available)
300-series SS internal components
Internal pointer dampening—no liquid fill required
500% burst pressure / 150% proof pressure rating
Solid front case design for safety
NIST traceable calibration available on request
New, never used in service. Quantity 1 available at this price. Manufacturer MSRP: $509.19. Listed at distributor pricing—below MSRP.
Ships from Louisiana, USA. Same or next business day handling. Combined shipping available on multiple units. Questions about compatibility, calibration certificates, or specifications? Send a message—happy to help.
