This optical refractometer is designed for measuring of ABW (alcohol by weight).
If you know the distillate weight in kilograms ("X") and measure alcohol percentage by weight ("Y") by using this refractometer, you can calculate the weight of pure alcohol in kilograms by multiplying both values and dividing the result by 100 (ABW = X * Y / 100).
This refractometer is not equipped with automatic temperature compensation.

The measurement
The liquids measuring is very easy. Place a few drops of measured liquid onto the prism, press slightly the cover plate to eliminate possible bubbles as well as air and the light/blue boundary will show you the result value.
For the most accurate measurement results must be respected the reference temperature of 20 °C.
