Frequently Asked Questions
How much does Fluke 120B Series 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 Fluke 123B, 124B, and 125B repairs are finished within 5–10 business days of arrival. Expedited turnaround is available if you’re down and need it back fast.
Is it worth repairing a Fluke 120B Series instead of replacing it?
Usually, yes. These are current-production, rugged instruments, and a component-level repair with recalibration typically costs far less than a new unit. We give you a firm quote up front so you can compare before deciding.
Do you do component-level repair or just swap boards?
Component level. We identify and repair the specific failed parts rather than replacing whole modules, which keeps your cost down and preserves your original instrument.
Is a calibration certificate included?
Yes. Every repair includes NIST-traceable calibration — we verify bandwidth, timebase, vertical accuracy on both inputs, trigger sensitivity, and the multimeter functions, and you receive a documented certificate against Fluke’s published specifications.
What if my exact model or accessory kit isn’t listed?
We service every 120B configuration, including the /S software-kit versions. If your model isn’t in the table, pick the closest match or email us — the evaluation and repair process is the same.
Who uses the Fluke 120B Series?
Industrial electricians, automation and HVAC technicians, field service engineers, and training programs rely on the 120B Series for portable scope, meter, and recording work.
