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.
June Company repairs and calibrates the Fluke 6331 for temperature-calibration labs.
Common Fluke 6331 problems we fix
- Stirrer-motor failure — poor uniformity or no circulation from a failed stirrer motor, replaced.
- Temperature-controller faults — won’t hold the setpoint or controller drift, repaired and recalibrated.
- Heater faults — won’t reach setpoint, the heater repaired.
- Stability or uniformity out of spec — control-loop faults, corrected.
- Display, leak, or interface faults.
FAQs
My 6331 stirrer failed or it won’t hold temperature — fixable? Yes. Stirrer and controller 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 submit a service request.
