The Modular Pressure Calibrator is unmatched by any device in its price range. For the majority of its available ranges, it has a typical pressure accuracy of 0.025% fullscale and an electrical accuracy of ±0.01%. That makes it four times more precise than the instruments it is used to calibrate, including 0.10% accuracy smart pressure transmitters. Even so, the modular pressure calibrator is priced competitively, with other pressure calibrators. The closest pressure calibration devices more accurate are far more expensive - lab instruments not intended for field use, such as quartz gauges used to calibrate other calibrators. Yet, remarkably, best of class accuracy is but one of the many reasons for specifying the modular pressure calibrator.
