Plato hydrometer temperature correction9/25/2023 For ☋rix to SG, another expression was generated by polynomial analysis: To get from any of those values back to specific gravity involves a rearrangement where possible. Thus, we time number of kg in one litre, by the number of grams dissolved per kg, and are left with the number of grams per litre. 'brix * 10' simply corrects the ☋rix value from being grams per 100 grams to being grams per kg. Most Bluetooth 4.0+ devices will work with the Tilt hydrometer. Compatible with Apple iPhone/iPad or Android smartphone/tablet or Tilt Pi. Don't have to open your fermenter or take a sample for a SG or temp reading. The gravity tells us how much 1 litre of the liquid weighs (in kg) - we then multiply this by the dissolved solids ratio to give dissolved solids per litre. Instantly check the specific gravity and temperature of your brew while it's fermenting. This allows us to calculate the dissolved solids, thus: Subtly, these measure different things, the specific gravity tells us the density of the liquid (grams per litre) and the ☋rix tells us the dissolved solids (percentage mass of solute to solution - grams per 100 grams). Grams per litre of dissolved solids is calculated from the specific gravity, and the ☋rix. ![]() Oechsle has a simple relationship with SG: Potential alcohol is calculated as discussed in the alcohol predicition section, with the assumption of a final gravity of 1.000, and a correction for DSOS of 0.007. If another value, such as Baume is provided, it is first converted to specific gravity, and then all other values are calculated from that.Ĭalculating ☋rix from SG is based on an expression from a polynomial fit to a large data set:īrix = 143.254 * sg 3 - 648.670 * sg 2 + 1125.805 * sg - 620.389 Every value is calculated from specific gravity.
