Schaffer Diaphragm Gauge

These gauges allow low pressure measurement on liquids were a standard capsule gauge would not be suitable. The diaphragm seal can prevent aggressive or contaminating medium from entering the internals of a conventional pressure gauge. They have a larger bore than a standard pressure gauge which also prevents clogging.
