Bourdon Tube Pressure Gauges

The manufacturing of the Wallace & Tiernan precision pressure gauges and calibrators has been relocated from Germany and are now being done in the U.S. by WIKA Instrument Corporation. They are certified to NIST Standards before shipment. The Certificate of Calibration is included at no additional cost
