Fluke 9143 Dry Well Calibrator Repair

Description

Fluke 9143 Dry-Well Calibrator Repair

The Fluke 9143 (Hart Scientific) is a field dry-well temperature calibrator — it heats a precision insert block to high, stable temperatures with fast heating/cooling 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 9143 for field-calibration and process teams.

Common Fluke 9143 problems we fix

• Heating faults — won’t reach the setpoint temperature, the heater repaired.
• Controller / reference drift — the controller or reference sensor reading the wrong setpoint, recalibrated against standards.
• 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 9143 won’t reach or hold temperature — fixable? Yes. Heating and controller faults are repairable, then 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.
