The Fluke 721Ex Precision Pressure Calibrator applies the dual-sensor 721 measurement concept to hazardous-area work.\u003c\/p\u003e\n\u003cp\u003eIt combines a low-pressure sensor—selected around 16 psi or 36 psi depending on configuration—with a separate high-pressure sensor for simultaneous differential and static pressure measurement. The catalogue identifies selected Ex configurations with high-pressure capability extending to 5000 psi. The stainless-steel sensors provide precision suitable for gas-flow calibration, while a Pt100 RTD input supports temperature measurement and the instrument can measure 4–20 mA process signals. The 721Ex is certified IECEx \/ II 2G ia IIB T3 Gb for Zone 1 applications.\u003c\/p\u003e\n\u003ch2\u003eIntrinsically Safe Custody Transfer Selection Guide\u003c\/h2\u003e\n\u003cp\u003eChoose the 721Ex where the dual-pressure capability of the 721 is required inside an approved hazardous area.
