The hydrometer is an instrument used to measure the specific gravity of the liquids. Specific gravity, as known as relative density, is the ratio of the liquid to the density of water at 20 °C. This plain form hydrometer does not have a built-in thermometer; using a separate thermometer to measure the temperature. The hydrometer contains dual scales inside the stem, so that the specific gravity can be read directly. The hydrometer measures specific gravity ranging from 1.000 - 2.000, Baume range from 0 - 72 degree. This hydrometer is used for heavy liquids heavier than water.

Ozone is a colourless toxic gas. It is irritating to eyes and mucous membranes and can cause respiratory complaints. An ozone content of 180 ¦g/m 3 is considered as critical value above which sensitive persons should avoid stronger physical exertion. The ozone values published by public media like press, radio or TV represent the ozone concentrations in the vicinity of the measuring stations. However, actual ozone values in other locations can considerably deviate from these published values due to meteorological and chemical influences such as wind, solar radiation, exhaust gases from vehicles etc. For this reason a local measurement of ozone concentrations is recommended. Method of application: Place a test stick in the open air, protected from wind. If necessary, fix the test stick with a piece of adhesive tape. After 10 minutes compare the test field with the colour scale on the container.
