Product Overview

PY803D Digital Differential Pressure Gauge is a high-accuracy instrument developed for precise differential pressure measurement in industrial, laboratory and calibration environments.

Its fully welded 316L stainless steel pressure chamber provides excellent resistance to high static pressure and corrosive media while eliminating sealing-ring leakage risks. Supporting differential pressure ranges up to 20 bar and static pressure resistance of 20 MPa, the PY803D delivers stable performance for gas, liquid and industrial process applications.

It is widely used for differential pressure calibration, process monitoring, filter monitoring, pressure testing and industrial instrumentation.
