For all owners of MISCO or VST refractometers, we offer a calibration service (adjustment) in the second point of the measuring range of the instrument (so-called SPAN). We perform it with an original master calibration liquid directly from the refractometer manufacturer - company MISCO Refractometers.
Purchase, ship the refractometer to our address, we will do the calibration and we will ship it back to you once it is finished.
