Fluke 6331 Calibration Bath Repair

The Fluke 6331 (Hart Scientific) is a precision calibration bath — it heats and stirs a liquid bath to precise, uniform, stable temperatures to calibrate temperature sensors, including multiple and odd-shaped probes. Its precision depends on the heater, the stirring system, the temperature control and reference, and the fluid handling, which is where service focuses.

FlukeMeterRepair.com repairs and calibrates the Fluke 6331 for temperature-calibration labs.

Common Fluke 6331 problems we fix

• Temperature-controller faults — won’t hold the setpoint or controller drift, repaired and recalibrated against standards.
• Fluid leaks — leaks in the bath vessel or fittings, repaired.
• Heater faults — won’t reach the setpoint, the heater repaired.
• Stirrer faults — poor uniformity from a failing stirrer, repaired.
• Interface faults.

FAQs

My 6331 controller is faulty or it’s leaking — fixable? Yes. Controller, leak, and heater 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.
