Scope

N/A

  • The Marquest Gauge Isolator provides two fluid chambers separated by an impermeable membrane. The upper chamber (instrument side) is normally filled with a stabilized liquid. The lower chamber receives the media under pressure.
  • Most pressure sensing devices are compatible with 1/4" FNPT outlet. The inlet is standard 1/2" FNPT or 1/4" FNPT.
  • Chemical resistance and purity levels are as recommended for the base materials.
  • No metals or lubricants are used in construction, internally or externally.
  • Custom membranes may be supplied upon request.

Materials of Construction

N/A

Body:

  • PVC: Polyvinyl Chloride
