Description

Fluke 721 Pressure Calibrator Repair

The Fluke 721 is a dual-sensor pressure calibrator — it measures two independent pressure ranges at once (a static/line pressure pairing) plus the mA loop signal, ideal for gas-flow and custody-transfer measurement. Its precision lives in the two internal pressure sensors and the mA circuit, which is where service and calibration focus. (Specific range pairings are sold as 721-xxxx variants.)

FlukeMeterRepair.com repairs and calibrates the Fluke 721 for gas-measurement and instrument-calibration teams.

Common Fluke 721 problems we fix

Pump rebuild — a worn pump/seal (where used for generation) that stops it building or holding pressure, rebuilt.
Pressure-sensor recalibration — one or both internal sensors drifting out of spec, recalibrated against standards.
Pneumatic seal replacement — worn seals or fittings that stop a range holding pressure, replaced.
Over-pressure damage — sensor damage from an over-range event on either range, assessed and repaired.
mA, display, or battery faults.

FAQs

One range on my 721 reads wrong — fixable? Yes. Sensor and seal faults are repairable and recalibrated against our reference standards so both ranges and the mA function are accurate, with a NIST-traceable certificate.

Are both sensors verified? Yes — each pressure range is checked against our standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
