Milwaukee Instruments Grape Must Refractometer with case - MR200ATC

Description

Product Description
The MR200ATC refractometer are precision optical Instruments used for measuring concentrations of Brix and Water in Grape Must. They work using the principle of light refraction through liquids. When passing light through a liquid the refracted angle will be shown on the scale determining the amount of dissolved solids in the liquid.  Very simple to use: simply place one drop of your sample on the prism and read the results on the scales immediately!
They have adjustable focus and they provide direct readings. Models with automatic temperature compensation (ATC) are suitable for applications where the temperature of the samples
varies.

Calibration
1. Lift up the daylight and put one or two drops of distilled water on the prism. Close the daylight, confirm that distilled water has spread over the entire prism surface.
2. Turn the bright direction and look at the scale through the eyepiece. If the boundary line doesn’t coincide with 0% turn the scale adjustment screw with a screwdriver until it
does.
