MISCO Refractometer Calibration Lab

How to Order Refractometer Calibration

The MISCO Certified Calibration program provides all the requirements for the confirmation of calibration accuracies for handheld refractometers and Abbe refractometers, and for the preparation and control of certified traceable measurement standards. The intention of this program is to minimize uncertainty of measurements and minimize the risk of refractometers producing results having unacceptable errors. Further, this program provides compliance with International Standard ISO 9000, ISO 10012-1:1992(E) and ANSI/NCSL Z540-1-1994.

To find the correct part number to order calibration for your MISCO refractometer:

1.) First, determine whether you need a Level I or Level II Certification and use the chart below. Level I and II certifications differ only in the amount of documentation you require. Level I certification is less expensive than Level II certification because of the paperwork burden associated with the additional documentation requirements. Full Descriptions of Level I and Level II documentation are below the chart.

2.) Next, using the chart, find the model number for your refractometer in the left-hand column. “X” represents a variable number, so you would choose 104XXVP for the models 10430VP, 10431VP, 10440VP, and so on.

Level I vs Level II Documentation

What is the difference between Level I and Level II documentation for my MISCO Refractometer?

Level I Certification fulfills the documentation and certification requirements of most quality control programs and is the form most often ordered. It is designed for those companies that are concerned with instrument precision but are not burdened by regulatory requirements for additional documentation. All Level I certified calibrations from the MISCO calibration laboratory come with a printed certificate containing the information listed below.

Level II Certifications are for those companies that strictly adhere to the documentation requirements of ISO/IEC 17025. All Level II Certifications will receive a certificate with the Level I information AS WELL AS additional information listed below
