Floor Model Primary Pressure Balance Standards

Below is a list of basic pressure balance information on the 6 different floor model primary standard systems. Each model has a number of different sized piston-cylinder assemblies available, allowing for a variety of pressure outputs using the same weight stack. Replacement piston-cylinder assemblies are available for all models. Pistons and cylinders are not interchangeable and cannot be sold separately due the exacting tolerances required in machining.
