MISCO Refractometer Warranty
and Non-Warranty Repair & Calibrations

If you’re in need of repair, calibration, or reprogramming for your refractometer, MISCO’s customer service and technical staff are here to assist you. We have decades of experience with the most demanding refractometer applications and are happy to walk you through how to use a new refractometer or troubleshoot an application issue.

Warranty / Non-Warranty Repair Service:

In the event that your refractometer needs to be returned to us for warranty or non-warranty service, we have an in-house repair lab staffed with qualified technicians that will promptly evaluate your refractometer. If it is a warranty issue, we will quickly repair or replace your refractometer, subject to the terms of our warranty policy. If it is a non-warranty issue, we will evaluate your refractometer, free of charge, and provide you with a quotation for the work. No work will be done without your approval.
