Fluke 9103 Dry Well Calibrator Repair

Description

Fluke 9103 Dry-Well Calibrator Repair

The Fluke 9103 (Hart Scientific) is a compact sub-zero dry-well temperature calibrator — it cools and heats a precision insert block to stable temperatures below ambient (using a Peltier system) to calibrate temperature sensors in the lab and field. Its precision depends on the Peltier cooling/heating system, the temperature control and reference sensor, and the insert/block, which is where service focuses.

FlukeMeterRepair.com repairs and calibrates the Fluke 9103 for calibration labs and field-service teams.

Common Fluke 9103 problems we fix

• Temperature-controller drift — the controller or reference sensor reading the wrong setpoint, recalibrated against standards.
• Insert / block faults — a worn or damaged insert bore affecting fit and uniformity, addressed.
• Peltier cooling faults — won’t reach or hold the sub-ambient setpoint, the Peltier system repaired.
• Stability out of spec — control-loop faults, corrected.
• Display or interface faults.

FAQs

My 9103 won’t reach its low setpoint — fixable? Yes. Peltier 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.
