Checking for live stock

The Fluke 721-3605 is a dual-sensor pressure calibrator built to generate and measure both static and differential pressure, useful for gas flow calibration, instrumentation testing, and pressure system verifications. It supports a wide pressure range up to 500 psi (≈ 34.5 bar), allowing engineers and instrumentation technicians to validate transmitters, flow computers, valves, and other devices under realistic operating conditions. The RS-calibrated unit comes with traceable certification, which adds confidence when used in calibration labs or quality-assurance processes.

Advanced Features and Benefits of the Fluke 721-3605 Differential Pressure Calibrator

  • Two isolated stainless-steel pressure sensors: one for low pressure (–0.97 bar to +2.48 bar / –14 psi to +36 psi) and one for high pressure (–0.83 bar to +34.5 bar / –12 psi to +500 psi). Accuracy: 0.025% of full scale.
  • Offers multiple measurement functions beyond pressure: accepts 4–20 mA transmitter signals, measures up to 30 V DC, and can supply a 24 V loop-power output, enabling testing of pressure transmitters and loop-powered sensors without external supplies.
  • Optional RTD (Pt100) input for temperature measurement, practical when calibrating temperature-compensated transmitters or testing systems where pressure and temperature both matter.
  • On-device, large, backlit graphic display shows up to three inputs simultaneously, enabling static pressure, differential pressure, and process signals to be viewed simultaneously.
  • Ability to store up to five instrument setups for quick recall, helpful when technicians switch between calibration tasks or field instruments frequently.

Practical Value for Engineers and Technicians

The 721-3605 stands out when you need a reliable, portable, and fully featured calibrator instead of bulky test benches. It lets you verify transmitters, sensors, and systems on-site, avoiding downtime during shutdowns or equipment removal. The dual-sensor design simplifies tasks by allowing both static and differential pressure tests with a single instrument.

Applicable Areas of the Product

  • Calibration or verification of pressure transmitters, sensors, and flow computers in oil & gas, chemical, HVAC, or industrial process environments.
  • Maintenance checks on pipelines, valves, and pressure-regulated systems.
  • Field commissioning of new installations.
  • Periodic recalibration of instrumentation.
