Description

Fluke 721-1630 Pressure Calibrator Repair

The Fluke 721 is a dual-sensor pressure calibrator — it measures two independent pressure ranges at once (this 1630 variant pairing a low static/line range with a higher one) 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.

FlukeMeterRepair.com repairs and calibrates the Fluke 721-1630 for gas-measurement and instrument-calibration teams.

Common Fluke 721-1630 problems we fix

Dual-sensor drift — one or both internal sensors drifting out of spec, recalibrated against standards.
Pressure-hold / leak faults — a leak that stops a range holding applied pressure, repaired.
mA measurement faults — the loop measurement, recalibrated.
Over-pressure damage — sensor damage from an over-range event on either range, assessed and repaired.
Display or battery faults.

FAQs

One range on my 721-1630 reads wrong — fixable? Yes. Sensor and leak 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.
