Fluke 6109A Calibration Bath Repair
The Fluke 6109A (Hart Scientific) is a portable calibration bath — it heats and stirs a liquid bath to precise, uniform, stable temperatures to calibrate temperature sensors, including odd-shaped and multiple probes, in the lab and field. Its precision depends on the heater, the stirring system, the temperature control and reference, and the bath-fluid handling, which is where service focuses.
FlukeMeterRepair.com repairs and calibrates the Fluke 6109A for temperature-calibration labs and pharma/process teams.
Common Fluke 6109A problems we fix
- Temperature-controller faults — won’t hold the setpoint or controller drift, repaired and recalibrated against standards.
- Heater faults — won’t reach the setpoint, the heater repaired.
- Stirrer faults — poor uniformity from a failing stirrer, repaired.
- Stability or uniformity out of spec — control-loop faults, corrected.
- Leak or interface faults.
FAQs
My 6109A controller or temperature is off — fixable? Yes. Controller, heater, and stirrer faults are repairable, then the bath is recalibrated so temperature is accurate, stable, and uniform, with a NIST-traceable certificate.
Is uniformity verified? Yes — stability and uniformity are checked against our reference standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
