The Advantages of Digiquartz® Technology
   Applications
The Digiquartz® Barometers are used in a variety of precision Meteorological applications.  The Model 745-16B and Model 765-16B are used as transfer standards in laboratory and field applications. These standards have been used in an international calibration and intercomparison study originated by the Norwegian Meteorological Institute (DMNI).  Additionally, barometers have been submitted to an ongoing long-term stability test.  Median drift rate of the units was -0.007 hPa (-0.0002 in Hg) per year. Pressure hysteresis tests showed a mean hysteresis less than 0.001 hPa.  

Other meteorological applications include use on marine data buoys, atmospheric wave and turbulence detectors, and altimeter-setting indicators.  More recently, the technology has been incorporated into automated surface observation systems that estimate atmospheric precipitable water vapor in conjunction with GPS (Global Positioning System) geodetic networks.
