The Model 745 and Model 765 are new next generation products with enhanced features.  These new products are direct replacements for Models 740 and Model 760 which are used as transfer standards in laboratory and field applications.  A six year test of a high pressure Model 760-10K showed rms conformance 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 with a median drift rate of -0.007 hPa per year.  Mean pressure hysteresis on a group of standard production barometers was 0.001% (0.01 hPa).

Measurements of the performance of primary pressure standards demonstrate the high resolution and accuracy  of Paroscientific Instrumentation.
