Pressure calibration and temperature measurement for gas transfer applications
The Fluke 721Ex precision pressure calibrator is the ideal instrument for gas transfer applications in potentially explosive atmospheres.
With two isolated pressure sensors, this instrument allows you to make static and differential pressure measurements simultaneously with a single instrument.
Key features:
The 721Ex can be configured by selecting a low-pressure sensor of 16 PSI (1.1 bar) or 36 psi (2.48 bar) and then adding one 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).
Intrinsically safe - IECEx and Atex Ex ia IIB T3 Gb (Zone 1) approved
