PR-11 Series
Ultra Sensitive Pressure Control Regulator

This precision pressure regulator has been designed to
allow the user complete flexibility in application. The
instrument design engineer can now choose the optimum
operating parameters he needs for a particular flow system. Flow and pressure regulation can now be easily and economically accomplished in laboratory and process
chromatographs, air pollution analyzers and other general
process and laboratory instruments. The low internal volume and no trapped areas mean efficient operation and cleanliness in instrumentation with high sensitivity detectors. The standard stainless diaphragm prevents permeability of undesired contaminants into the flow stream. This regulator offers greater pressure and flow stability for critical applications such as chemiluminescent type analyzers and is considered the ultimate in maximum
stability with ambient temperature change. The PR-11 Series has truly been designed by experienced instrumentation engineers for use in that industry.
