Applications

  • Subsea in compensated subsea environments: Tested to working depths of up 10,000 feet of sea water
  • Suitable for corrosive environments and gaseous or liquid media that will not obstruct the pressure system

Product features

  • Excellent load-cycle stability and shock resistance
  • All 316 stainless steel construction
  • Positive pressure ranges to 20,000 psi (1,600 bar)
  • Black dial face with white enlarged numerals for subsea visualization
  • Matte black finish case and mounting hardware for low reflectivity
