Fluke 9150 Thermocouple Furnace Repair

The Fluke 9150 (Hart Scientific) is a thermocouple furnace — a compact high-temperature furnace (to ~1500 °C) that heats a uniform zone to calibrate thermocouples. Its precision depends on the heating system, the temperature control and reference sensor, and the furnace insert, which is where service and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 9150 for calibration labs and metrology teams.

Common Fluke 9150 problems we fix

• Reference-source recalibration — the reference sensor reading the wrong temperature, recalibrated against standards.
• Heating / output-stage faults — won’t reach the setpoint, the heater/output repaired.
• Stability faults — temperature not holding stable, the control loop corrected.
• Insert / well faults — a worn or damaged furnace insert, addressed.
• Display, interface, or power faults.

FAQs

My 9150 won’t reach or hold temperature — fixable? Yes. Heating and control faults are repairable, then it’s recalibrated so the furnace temperature is accurate and stable, with a NIST-traceable certificate.

Is stability verified? Yes — temperature and stability are verified against our standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
