Description

Fluke 9170-A-156 Metrology Well Calibrator Repair

The Fluke 9170-A-156 (Hart Scientific) is a configuration of the 9170 metrology-grade dry-well temperature calibrator — it heats and cools a precision insert block to highly stable, accurate temperatures with low gradients to calibrate temperature sensors (this A/156 configuration). Its precision depends on the heating/cooling system, the temperature control and reference sensor, and the insert/dry block, which is where service focuses.

FlukeMeterRepair.com repairs and calibrates the Fluke 9170-A-156 for calibration labs and metrology teams.

Common Fluke 9170-A-156 problems we fix

• Ramp-rate / stability faults — the heating/cooling ramp rate or stability out of spec, the control loop corrected.
• Heating/cooling faults — won’t reach or hold the setpoint, the heater/cooling system repaired.
• Insert / dry-block faults — a worn or damaged insert bore, addressed.
• Temperature-controller drift — the controller or reference sensor reading the wrong setpoint, recalibrated against standards.
• Display or interface faults.

FAQs

My 9170-A-156 won’t hold temperature — fixable? Yes. Heating/cooling and control faults are repairable, then recalibrated so block temperature is accurate and stable, with a NIST-traceable certificate.

Is stability verified? Yes — stability and ramp performance are verified against our reference standards.

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