Description
Fluke 729 Automatic Pressure Calibrator Repair
The Fluke 729 is an automatic pressure calibrator — it generates and automatically regulates pressure to a setpoint with an internal pump, measures pressure and the mA loop signal, and documents results, to calibrate pressure transmitters in the field. Its precision lives in the internal pump and auto-regulation, the pressure sensor, and the mA circuit, which is where service and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 729 for process and instrument-calibration technicians.
Common Fluke 729 problems we fix
- psi-accuracy / sensor drift — the internal pressure sensor drifting out of spec, recalibrated against standards.
- Pump / auto-regulation faults — won’t build or automatically hold the setpoint, the pump and control repaired.
- mA source/measure faults — the loop measurement drifting, recalibrated.
- Pneumatic / leak faults — leaks that stop it holding pressure, repaired.
- Display or battery faults.
FAQs
My 729 won’t hold the setpoint or reads wrong — fixable? Yes. Pump, control, and sensor faults are repairable, then the calibrator is recalibrated so pressure and mA are accurate, with a NIST-traceable certificate.
Is the full range verified? Yes — pressure and mA are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.

Our Fluke 729 had an initial fault when purchased. Bad design when it came to the pump, so incredibly slow. We still used it until the connectors became intermittent. Sent to June Company, and they not only repaired the connectors but also improved the automatic pump drastically, saving our field engineers a lot of time.
