pH Strips pH strips allow you to test the acidity of a particular liquid. pH strips measure on a scale of 14 where seven is neutral. Lower numbers are increasingly acidic, while higher numbers are increasingly alkaline (or basic). Water, being a neutral liquid, should register a seven. Compare the colour of the strip to the chart provided with the strips. Acids are represented with warmer colours (red, orange, etc) while alkalines are represented with cooler colors (blue, green, etc). …

What is the difference between SG Hydrometers and Density Hydrometers?All hydrometers work on the principle of displacement, however there are two common types to choose from and the below descriptions can help choose which type may be suitable for your application.Density HydrometersDensity hydrometers read mass by unit of volume at a given temperature. For example, a reading of 1200 on an Australian Standard density hydrometer indicates that the liquid has a mass of 1200kg per cubic meters …

Alcoholometers (alcohol hydrometers) are used to read the alcohol content of pure distilled spirits. Alcoholometers should only be used in pure, distilled spirits when determining the alcohol % or proof of the spirit before it is added to anything else. Alcoholometers are calibrated to the density of pure ethanol and won't sink as deep when water is added to the mixture. All Alcoholometers which are manufactured according to AS2371 are supplied with a Certificate of Conformity. Usin …
