Description

Fluke 721-3603 Pressure Calibrator Repair

The Fluke 721-3603 is a dual-sensor pressure calibrator: two isolated pressure sensors in one instrument, so static and differential pressure can be read simultaneously. It was built for gas custody transfer and flow-computer work, where a small error becomes a measurement dispute rather than an inconvenience. Two sensors means two independent things that can drift.

The Fluke 721-3603 is repaired at June Company by certified technicians who work on this class of instrument daily, for gas measurement technicians, custody transfer teams, and pipeline instrument crews. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.

Common Fluke 721-3603 problems we fix

  • Display, keypad and battery faults.
  • One sensor drifted, the other reading correctly – the classic 721 symptom – and the reason a single-point check misses it.
  • Both sensors out of tolerance – corrected and verified independently against reference standards.
  • Static and differential readings disagreeing – the relationship between the two channels, which is the whole point of this instrument.
  • mA loop measurement faults.
  • Pressure port leaks on one channel.

FAQs

Can you work on an instrument that is out of warranty or discontinued? Yes. Most of what we service is past its manufacturer support window, and component-level repair is exactly what that situation needs.

Only one of my two sensors is off – do you repair both? We verify both channels regardless of which one you report, because a single-channel check is exactly how the other one gets missed.

Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
