Refractometers are optical precision instruments that determine the density of a liquid by the refractive index, with only a few drops! Suitable for juices, wort, honey, etc. Also for use in the vineyard. Accurate yet simple to use: just place a few drops of liquid on the prism, point the refractometer towards a light source and you have an immediate reading of the density. They are supplied with box, screwdriver for easy calibration and pipette.
Refractometer BEER 0 - 18° Plato with ATC:
- Model specially for beer brewers.
- Ideal for checking your wort during reducing, as well as monitoring the rinsing of the brewers' grain.
- Scale 0 - 18°, per 0.1°.
- With ATC (automatic temperature correction between 10 and 30°C)
Glass hydrometers follow the â€˜principle of Archimedesâ€™: Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.
The gram is the mass of 1 cubic centimeter (1 cc or 1 ml) of pure water. There are a few units used for sugar measurement that have a direct relation with a weight unit. Other units however have a connection with the density or specific gravity. The specific gravity is the weight per unit of volume (g/cmÂ³). The specific gravity of pure water is 1 g/cmÂ³. The s.g. of water is 1 (1.000).
