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 lubricants are used in construction, internally or externally.
Custom membranes may be supplied upon request.
