Description

Fluke 721-1601 Dual Sensor Pressure Calibrator

Pressure Calibration and Temperature Measurement for Custody Transfer Applications

*Important Calibration Information: 

This instrument comes complete with the manufacturer’s calibration certificate. Please be aware that these certificates are generic and may also be time-lapsed. If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply. 

Overview:

The ideal tool for gas custody transfer applications is the Fluke 721 Precision Pressure Calibrator. With dual isolated pressure sensors, it allows you to take simultaneous static and differential pressure measurements with a single tool.

The 721 can be configured by selecting either a 16 PSI (1.1 bar) or 36 psi (2.48 bar) low-pressure sensor then adding 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). 

Key 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

Fluke 721-1601 Comes Supplied With:

  • Dual Sensor Pressure Calibrator, (PSI Varies on model)
  • Soft case
  • Four (4) AA batteries
  • Manual
  • Traceable calibration certificate
  • Test leads
