Fluke 721EX Precision Pressure Calibrators

Fluke 721EX Precision Pressure Calibrators

The Fluke 721EX Precision Pressure Calibrators with dual isolated pressure sensors are the ideal tools for gas custody transfer applications allowing 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).

The Fluke 721EX is the intrinsically safe version of the 721. It meets the standards for IECEx and Atex Ex ia IIB T3 Gb (Zone 1).
