High Accuracy
0.025% of full scalePressure calibration and temperature measurement for custody transfer applications. The ideal tool for gas custody transfer applications in potentially explosive atmospheres is the Fluke 721Ex Precision Pressure Calibrator. With dual isolated pressure sensors, it allows you to take simultaneous static and differential pressure measurements with a single tool. The 721Ex can be configured by selecting either a 16 PSI (1.1 bar) or 36 psi (2.48 bar) low pressure sensor then add any of 7 high pressure ranges including 100, 300, 500, 1000, 1500, 3000 or 5000 psi (6.9, 20, 24.5, 69, 103.4, 200, 345 bar).
