Fluke 9140 Dry Well Calibrator Repair

Description

Fluke 9140 Dry-Well Calibrator Repair

The Fluke 9140 (Hart Scientific) is a field dry-well temperature calibrator — it heats a precision insert block to high, stable temperatures 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 9140 for field-calibration and process teams.

Common Fluke 9140 problems we fix

• Heating-element 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 9140 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.
