Reference 4353252

Brand Fluke Electronic

The Fluke 721 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 features inputs for mA, switch contacts, and an RTD probe. An external pressure module option gives a wider range of pressure calibration options that include absolute and differential pressure measurement.

The Fluke 721 Series of products are ideal for gas custody transfer measurements with ranges, accuracies and capabilities specifically tailored to address gas custody transfers. The Fluke 721 Series has an optional RTD probe for a complete solution for testing flow computers and instruments used in gas flow measurement.

The 721 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.

FEATURES:

Ideal for gas flow calibration (custody transfer) applications.
Two isolated, stainless steel, pressure sensors with 0.025 % accuracy.
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, check 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.
