The
Model 745 and Model 765 are used as portable transfer standards
in laboratory and field applications. A six
year test of a high pressure Model 760-10K showed rms
conformance of better than 0.002% of full scale and a total
error of less than 0.008%. These standards have also been used
in an international
calibration and intercomparison study originated by the
Norwegian Meteorological Institute (DMNI). Additionally,
barometers are in an ongoing
stability test a median drift rate
of -0.007 hPa per year. Mean
pressure hysteresis on
a group of standard production barometers was 0.0001% (0.001 hPa).
Measurements
of the performance of primary
pressure standards
demonstrate the unique high resolution and accuracy of
Paroscientific Instruments.
Mass Flow Calibration
Systems with unparalleled performance and ease-of-use have been developed with Digiquartz® transducers.
