Status: 754 / 753 / 725 Current Production — 741B / 743B / 744 Discontinued. We repair and calibrate all of them.
Common Fluke Process Calibrator Problems We Fix
- mA source or measure out of tolerance / drifting
- No output / won’t source or simulate
- Thermocouple or RTD reading inaccurate
- Pressure module not reading / connector corrosion
- HART communication not working (753 / 754)
- Won’t power on / battery compartment corrosion
- Dead or faded display (older 741B / 743B / 744)

Frequently Asked Questions
How much does Fluke process calibrator repair cost?
Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the unit, you get a firm quote before any work begins — no surprises.
How long does the repair take?
Most 725, 753, and 754 repairs are finished within 5–10 business days of arrival, with expedited turnaround available if you need it back fast.
My calibrator’s source or measure is out of tolerance — can you fix it?
Yes. mA source/measure drift and thermocouple reference-junction degradation are the most common process calibrator faults. We repair the cause and verify source, simulate, and measure functions against our reference standards.
The HART communication on my 753/754 stopped working — can you repair it?
Yes. HART modem faults that prevent smart-transmitter configuration are a common 753/754 repair, restored so you can communicate with and document transmitters again.
Do you repair the intrinsically safe 725Ex?
Yes. We repair and recalibrate the 725Ex. Because it’s rated for hazardous areas, we verify it returns to specified performance, documented on a NIST-traceable certificate.
Do you still repair the discontinued 741B, 743B, and 744?
Yes. These legacy documenting calibrators are fully supported for repair and recalibration — including display faults common on older units — even though they’re no longer in production.
What if my exact model isn’t listed?
We service every Fluke process calibrator configuration. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses Fluke process calibrators?
Process instrumentation technicians, oil and gas facilities, pharmaceutical and food production, chemical plants, and water treatment facilities rely on the 725, 753, and 754 for sourcing, simulating, and documenting calibrations.
