A refractometer is an optical instrument that measures the density of a liquid using the refractive index. Primarily used for measuring the density before fermentation.
Place a few drops of wort or juice on the prism and read the original gravity.
Triple scales: °Oechsle (0 - 230) (1.000 - 1.230 Specific Gravity), °Brix (0 - 50) and KMW = °Babo (0 - 42).
Automatic temperature correction between 10 and 40 °C.
Includes a 9 V-battery and instructions in English. The battery lasts for up to 500 uses.
Single-point calibration with steam distilled water.
