Technical Data

Product highlights

The 721 and 721Ex can be conﬁgured by select-

ing 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).

•Intrinsically Safe (721Ex version only) – IECEx

and Atex Ex ia IIB T3 Gb (Zone 1)

•Ideal for gas ﬂow calibration (custody transfer)

applications

•Two isolated, stainless steel, pressure sensors

with 0.025

% accuracy

•Switch test on both pressure inputs

•Pressure displayed in the user’s choice of 19

engineering units

•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 (721 models only)

•Measure up to 30 V dc, check 24 V loop power

supplies (721 models only)

•Extend pressure measurement range with

connection to one of 50 external 750 series

pressure modules from 0 to 1 inH20 to 10,000

psi (2.5 mBar to 690 bar) (721 models only)

•Large backlit graphic display can display up to

three inputs simultaneously

•Store ﬁve instrument setups for recall and use
