Test & measurement · bought, sold, repaired, calibrated

Every instrument here is a real unit on our shelf, serial, photos, and all.

We started Aumictech because labs kept running into the same wall: OEM quotes taking months, used equipment with no real condition info, and no one who'd pick up the phone and actually know the instrument. So we built the shop we wished existed. Every unit gets evaluated before it's listed. If it needs calibration, we do it in-house to NIST-traceable standards with a cert. If something's wrong with it, we fix it first, or tell you exactly what's wrong if we list it as-is.

No hidden condition

Every listing has the actual serial number, real photos of that specific unit, and honest condition notes. If there's rack rash or a worn knob, we say so. You know what you're buying.

All work in-house

Repairs and calibrations are done by us, not outsourced. Same team that evaluates and lists the instrument handles the bench work.
