Fluke 9190A Temperature Calibrator Repair

Description

Fluke 9190A Dry-Well Temperature Calibrator Repair

The Fluke 9190A (Hart Scientific) is an ultra-cool field metrology well — a dry-well temperature calibrator covering a wide low-to-moderate range (to ~-95 °C) with high stability for field calibration of temperature sensors. Its precision depends on the refrigeration/cooling and heating system, the temperature control and reference sensor, and the insert/block, which is where service focuses.

FlukeMeterRepair.com repairs and calibrates the Fluke 9190A for field-calibration and metrology teams.

Common Fluke 9190A problems we fix

• Temperature-controller drift — the controller or reference sensor reading the wrong setpoint, recalibrated against standards.
• Cooling / refrigeration faults — won’t reach the low setpoint, the cooling system repaired.
• Heating faults — won’t reach the high setpoint, the heater repaired.
• Stability or uniformity out of spec — control-loop faults, corrected.
• Display or interface faults.

FAQs

My 9190A won’t hold its low setpoint — fixable? Yes. Cooling 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.
