The Fluke 721 Series of Dual Range Pressure Calibrators is ideal for gas flow calibration (custody transfer) applications with ranges, accuracies and capabilities specifically tailored to address gas custody transfers.

• Two isolated, stainless steel, pressure sensors with 0.025% f.s. accuracy
• Can be configured by selecting either a 16 psig (1.1 bar) or 36 psig (2.48 bar) low pressure sensor and then adding your choice of 7 high pressure ranges
• External pressure module connection supports all pressure modules (29 ranges) for even more measurement capability
• Temperature-compensation ensures accuracy in field applications
• Pt100 RTD input for temperature measurement, accurate to 0.1°C (0.2°F) (Requires optional RTD probe sold separately)
• Measure 4-20 mA signals
• Internal 24 V Loop Power Supply can power a transmitter under test
• Measure up to 30 V DC
• Large graphic style LCD with backlight can be configured to display up to 3 inputs simultaneously (i.e. pressure 1, pressure 2, and RTD or any combination of inputs)
• Pressure displayed in the user\'s choice of 19 engineering units
• Switch test on both pressure inputs, or external pressure module
• Operating mode layers support simple measurements to complex applications
• Up to five frequently used setups can be stored; last setup automatically recalled on power-up
• % error and damping functions
