Fluke 721Ex Precision Pressure Calibrator

Product Detail

The Fluke 721Ex Precision Pressure Calibrator comes equipped with dual isolates pressure sensors, allowing for simultaneous static and differential pressure measurements to be done with one isntrument. It is ideal for gas custody applications, even in potentially hazardous atmospheres. The Fluke 721Ex can be configured by selecting either a 16 PSIG (1.1 bar) or 36 PSIG (2.48 bar) low pressure sensor then add any of 7 high pressure ranges including 100, 300, 500, 1000, 1500, 3000 or 5000 psig (6.9, 20, 24.5, 69, 103.4, 200, 345 bar).

The 721-Ex reads pressure in the following pressure psig, bar, mbar, kPa, kgcm2, cmH2O@4°C, cmH2O@20°C, mH2O@4°C, mH2O@20°C, inH2O@4°C, inH2O@20°C, inH2O@60°F, mmHg@0°C, inHg@0°C, ftH2O@4°C, ftH2O@20°C, ftH2O@60°F
