Martel Gauge II Model 325 Pressure Calibrator

Martel Gauge II Model 325 Pressure Calibrator

     The process industries are quite literally under pressure.  There's a lot of pressure instrumentation out there (one source estimates nearly 75% of all field calibrations involve some type of pressure variable). There’s a lot riding on this instrumentation - process quality, plant safety, company profits. And a lot of the instrumentation rides on calibration accuracy.

     That's why we weren't about to introduce just another pressure calibrator. We wanted to develop a successor that would significantly improve upon our own bestselling BetaGauge™. We wanted to meet calibration requirements now and into the next decade.

     By any measure, we satisfied that design criterion and then some.  BetaGauge II™ is a quantum leap over every other DPG on the market. Over other pressure calibration devices like dead weight testers. Even overour own BetaGauge 320.

     In terms of accuracy, the most critical feature of any calibrator, BetaGauge II 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, BetaGauge II is priced competitively with distant second 0.05% pressure calibrators.

     The closest 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 many reasons for specifying the BetaGauge II.
