Description
Fluke 729 Automatic Pressure Calibrator Repair
The Fluke 729 is an automatic pressure calibrator with an internal electric pump that automatically generates and regulates a target pressure, measures it, and documents results to calibrate pressure transmitters and gauges. Its accuracy depends on the pressure-generation/measurement system, the seals and fittings, and the sensor, which is where service and calibration focus.
FlukeServiceCenter.com repairs and calibrates the Fluke 729 for instrument-calibration technicians, process engineers, and pharmaceutical production teams.
Common Fluke 729 problems we fix
- Leak-rate faults — internal leaks preventing stable pressure, found and resealed.
- Internal-pump / auto-regulation faults — won’t reach or hold the target pressure automatically, the pump and regulation repaired.
- Pressure-sensor / module drift — the measurement out of spec, recalibrated against standards.
- Display or interface faults — repaired.
- Battery or connection faults.
FAQs
My 729 reads or holds pressure wrong — fixable? Yes. Sensor, seal, and pump faults are repairable, then it’s recalibrated so pressure measurement (and sourcing, where fitted) is accurate, with a NIST-traceable certificate.
Is it leak-tested and verified? Yes — checked leak-free and against our pressure standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
