Fluke 9144 Dry Well Field Calibrator Repair

Description

Fluke 9144 Dry-Well Field Calibrator Repair

The Fluke 9144 (Hart Scientific) is a high-temperature field dry-well calibrator — it heats a precision insert block to high, stable temperatures (to ~660 °C) with fast heating for field calibration of temperature sensors. Its precision depends on the heating system, the temperature control and reference sensor, and the insert/block, which is where service focuses.

FlukeMeterRepair.com repairs and calibrates the Fluke 9144 for field-calibration and process teams.

Common Fluke 9144 problems we fix

• Reference-source / controller degradation — the controller or reference sensor reading the wrong setpoint, recalibrated against standards.
• High-temp heating faults — won’t reach the high setpoint, the heater repaired.
• Stability or uniformity out of spec — control-loop faults, corrected.
• Insert / block faults — a worn or damaged insert bore, addressed.
• Display or interface faults.

FAQs

My 9144 won’t reach high temperature — fixable? Yes. Heater and controller faults are repairable, then the control is recalibrated so block temperature is accurate and stable, with a NIST-traceable certificate.

Is stability verified? Yes — verified against our reference standards.

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