   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 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.  

Frequency output transducers can be connected to an intelligent electronic card to make a system capable of RS-232 and RS-485 operation.

A two line LCD digital display, the Model 715, can be connected to all new Paroscientific transmitters with
RS-232 and RS-485 outputs to provide digital readout of pressure, temperature, engineering units, overpressure warning, tare indication, user defined messages and a horizontal bar graph showing percentage of full-scale pressure.
