Capsule Schaffer Low Pressure Diaphragm Gauge

Introduction :

A Capsule Schaffer Low-Pressure Diaphragm Gauge is a precision instrument used to measure very low pressures, particularly in applications involving gases or air. It is designed with a capsule-type diaphragm that provides high sensitivity to small pressure changes. This design allows for accurate measurement of low and differential pressures. These Gauges are ideal for measuring pressure in the range of inches of water column (inH₂O) or millibar (mbar).
