PK II Deadweight Tester

PK II Deadweight Tester

The PK II Pneumatic Deadweight Tester is a primary pressure calibration standard designed for accurate generation and measurement of gas pressure. Using calibrated piston-cylinder assemblies and precision weights, it provides highly stable and repeatable pressure output for laboratory and field calibration of pressure gauges, transmitters, and sensors. Its pneumatic operation makes it ideal for clean, low-to-medium pressure calibration applications.
