The Fluke 721 Precision Pressure
Calibrator with dual isolated pressure
sensors is the ideal tool for gas custody
transfer applications allowing you to
take simultaneous static and differential
pressure measurements with a single
tool.
The 721 can be configured by selecting
either a 1.1 bar or 2.48 bar low pressure
sensor then add any of 7 high pressure
ranges including 6.9, 20, 24.5, 69, 103.4,
200, 345 bar.
• Ideal for gas flow calibration
(custody transfer) applications
• Two isolated, stainless steel, pressure
sensors with 0.025 % accuracy
Pressure calibration and temperature
measurement for custody transfer
applications
• Pt100 RTD input for temperature
measurement, (probe optional)
• Measures 4 to 20 mA signals
• Internal 24 V loop power supply can
power a transmitter under test
• Measure up to 30 V DC,
chec 24 V loop power supplies
• Extend pressure measurement range
with connection to external 700 series
pressure modules (29 ranges)
• Large backlit graphic display can display
up to three inputs simultaneously
• Store five instrument setups for recall
and use
