Calibration Standards for Flow Cups

It is important for accurate viscosity results to calibrate your viscometer correctly. In order to help with the calibration of your viscometer with various flowcups, we have provided a useful reference table that outline the viscosity standards for the calibration of a variety of flow cups.

If you feel unable to calibrate your own viscometer, we offer a comprehensive viscometer calibration service. More information can be found by contacting us.
