Frequently Asked Questions
How much does Fluke calibration bath repair cost?
Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the unit, you get a firm quote before any work begins — no surprises.
How long does the repair take?
Most calibration bath repairs are finished within 5–10 business days of arrival, with expedited turnaround available if your lab is down.
My bath won’t hold a stable temperature — can you fix it?
Yes. Poor stability or uniformity is usually a stirring-motor, heater, or controller fault — the most common bath repairs. We restore performance and verify stability and uniformity against our reference standards.
My sub-ambient bath won’t cool — can you repair the refrigeration?
Yes. Refrigeration compressor and cooling-system failures on sub-ambient models are a routine repair, restored so the bath reaches its full low-temperature range again.
Do you handle bath fluid leaks and contamination?
Yes. We repair fluid seal failures and address contamination that affects thermal performance. Please drain the bath fluid before shipping, and contact us if you need handling guidance.
Is the repair NIST-traceable, and do I get a certificate?
Yes. Every repair includes NIST-traceable calibration with a documented certificate against the manufacturer’s published specifications.
What if my exact model isn’t listed?
We service every Fluke calibration bath configuration. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses Fluke calibration baths?
Temperature metrology labs, calibration service providers, pharmaceutical quality teams, petrochemical process calibration, and aerospace sensor calibration rely on these baths for reference-level temperature work.
