Fluke 721-1601 Dual Sensor Pressure Calibrator
Pressure calibration and temperature measurement for custody transfer applications.
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 Fluke 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.
