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 CPVC: Chlorinated Polyvinyl Chloride PP: Polypropylene homopolymer, glass & mineral reinforced Membrane: Standard: PTFE, also available in: FPM: Viton®, Fluorine elastomer EPDM: Ethylene Propylene elastomer
Features	N/A Protects and isolates pressure sensing instruments Total isolation from system media Low profile design eliminates dead volume Convoluted diaphragm allows accurate transmission of system pressure Optimum pressure containment spherical design Low in original cost and maintenance Simple installation
