The manufacturing of these  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

Series 300 2 " Dial High Precision Absolute Pressure Gauges

For routine test, laboratory, and production uses, this gauge gives accuracy and compact size. Its mechanism is sensitive yet rugged. And it offers high accuracy at low cost. Available in ten standard ranges, the Series 300 is convenient to use. Absolute pressure is applied to the case and readout is direct, without barometric or temperature corrections. Readings are referenced to zero absolute.
