How It Works:
The Atago Ethyl Alcohol Digital Refractometer operates on the principle of measuring the refractive index of the liquid sample. The refractive index of a liquid changes in relation to its alcohol concentration. By shining light through the liquid and measuring the angle at which light is bent (refracted), the refractometer can calculate the alcohol content with high precision.
Steps for Using the Atago Ethyl Alcohol Digital Refractometer:
-
Calibration:
- Calibrate the refractometer using a standard reference solution, usually distilled water or a calibration solution specific to alcohol measurements.

Revolutionary new External Light interference (ELI) feature Patented When intense light penetrates the prism of a digital refractometer, the light waves interfere with the sensor, which may lead to inaccurate measurements. To ensure accurate measurement results, the PAL is programmed with the ELI function which displays the [nnn] warning message when intense direct light is detected. Forming a habit of shading the sample stage with your hand and re-pressing the START key (when the warning message from the ELI function is displayed) will ensure accurate measurement results each time |
