AL80 Scale Alcohol Meter, Alcohol Measurement Range 0~80%, ROCKER (CAT#: STEM-AIAE-3315-LGZ)

The alcohol meter uses the principle that when light penetrates liquids of different concentrations, the refraction angle will change to measure different alcohol concentrations or changes in the refractive index of other substances to convert his actual concentration.

Alcohol measurement range: 0~80%
Accuracy: ±1%
Resolution: 1%

Alcohol content should be measured by volume. The correct label should be percentage (%). However, it is usually indicated by "Degrees", so 20% by volume is the same as 20 degrees.
