The hydrometer is a measuring instrument for determining the density or specific gravity of liquids. The instrument is immersed in a liquid until the weight force of the displaced liquid corresponds to the weight force of the immersed body. Hydrometers are used, among other places, in laboratories, dairies or wineries (must scales) used.
For accurate density measurement and to ensure an exact measurement result, make sure to use a container (stand cylinder, see accessories) with the appropriate size or capacity. In addition, the temperature of the liquid should correspond to the reference temperature of the instrument (as a rule +15 °C to +20 °C).
Proudct Varians:
Alcoholometers
Alcoholometers are used to determine volume concentration or content of alcohol in alcohol-water-mixtures. The percentage of alcohol content can be read directly from the scale. They are available either as range finders (0-100 percent by volume) or as finely scaled hydrometer sets. Precision alcoholmeters can be implemented either with or without thermometer. Integrated thermometers are available with organic, environmentally-friendly filling.

Hydrometers for liquid gases
Precision hydrometer for liquid gases are used for measurements in liquid hydrocarbons as e.g. propane, butane, mixtures there of or like media To retain liquidity a pressure of up to 15 bar is possible at +15 °C. The thermometer tube is enclosed in an additional glass guard which helps avoid faulty reading due to pressure to the thermometer tube.. Common norms specifications like DIN 12804 and ASTM E100-19 are complied with, of course.

Hydrometers for dairies
Lactometers are used to supervise and control production in dairies, the cheese industry, milk processing plants, and laboratories. They determine the density of milk, skim milk, buttermilk, condensed milk and other liquids of the dairy industry.
The different shapes of the instruments and their ranges are adapted to their use. Hydrometers for dairies in versions with or without integrated thermometers available. Because of the opaqueness of milk these instruments are always to be read at the top, and the scale is at the top of the stem. The instrument has a thermometer in body. We offer our lactometers with eco-friendly, mercury-free filling.
