Triple scale refractometer for wine or confocal beer adjustable with automatic temperature compensation (ATC) for applications where the sample temperature varies.
Refractometer with automatic 3-scale temperature compensation
0-140 OECSHLE
0-26 BABO
0-32 BRIX
It works using the principle of refraction of light through liquids.
When the light passes through a liquid, the angle of refraction will be shown on the scale, determining the concentration of the substances in the liquid.
