PR-11 Series Ultra Sensitive Pressure Control Regulator

General Details

This precision pressure regulator has been designed to allow the user complete flexibility in application. The instrument 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 steel diaphragm prevents permeability of undesired contaminants into the flow stream.

This low tempco regulator offers greater pressure and flow stability for critical applications such as chemniluminescent 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 by the instrumentation industry.
