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
