Low Pressure Sensor: -14 psi to +16 psi, -0.97 bar to 1.1 bar. High Pressure Sensor: -12 psi to +100 psi, -0.83 bar to 6.9 bar.

The Fluke 721 Ex Pressure Calibrator is a simple to use and versatile pressure calibrator. The two internal pressure sensors are configured with different pressure measurement ranges. One range for lower pressure (P1) and one range for higher pressure (P2). The Fluke 721 Ex features inputs for mA, switch contacts, and an RTD probe. With IECEx and Atex Ex ia IIB T3 Gb (Zone 1) ratings, the 721Ex is available in 14 models and can be used with a Fluke 720RTD probe for temperature measurement. The rugged dual-range pressure calibrator features two isolated, stainless steel, pressure sensors with accuracies to ±0.025 per cent full scale.

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 721 Ex has been designed for use in Ex-Hazardous Areas. These are areas where potentially flammable or explosive vapors may occur. These areas are referred to as hazardous (classified) locations in the United States, as Hazardous Locations in Canada, as Potentially Explosive Atmospheres in Europe and as Explosive Gas Atmospheres by most of the rest of the world.
