Description
Fluke 725 Process Calibrator Repair
The Fluke 725 is a multifunction process calibrator — a handheld instrument that sources and measures process signals (mA, voltage, RTD, thermocouple, frequency, and pressure with a module) to calibrate process transmitters and instruments. Its faults concentrate in the source/measure front-ends, the internal reference, and the interface electronics.
FlukeMeterRepair.com repairs and calibrates the Fluke 725 for process-instrument and commissioning teams.
Common Fluke 725 problems we fix
- Internal-pump wear — a worn pump/seal (on pressure work) that stops it generating or holding pressure, serviced.
- Source/measure out of spec — a process function (mA, RTD, T/C, V) drifting, recalibrated against standards.
- A function dead — an input/output path failed, often after a miswire, repaired.
- Pressure-module interface faults — the module input not reading, repaired.
- Display or battery faults.
FAQs
My 725 sources or measures wrong — fixable? Yes. Front-end and reference faults are repairable, then every function is recalibrated against our standards so the transmitters you calibrate are trustworthy, with a NIST-traceable certificate.
Are all functions verified? Yes — each source/measure function is 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 725 process calibrator is very important for our company field service division. The meter became erratic not only for the readings, but the display started to lose segments intermittently. The meter came back in perfect working order with calibration certificates.
