Carlton manufacture a range of precision Alcoholometers to Australian Standard AS2371. Each covers a range of 20% alcohol by volume at 20°C, with subdivisions of 0.2%/vol.. These are commonly used to determine the concentration of ethanol in the wine and beverage industry.
Note that ONLY the 20% range conform to the standard, as the standard it does not allow for 10% ranges. They are still however a popular choice for the smaller subdivisions of 0.1%/vol.
Note that an alcoholometer only measures ethanol in water. That is, if there is sugar or other substances dissolved in the solution, you will not get accurate alcohol readings. The ethanol must first be distilled out of the solution and mixed back to the same volume with distilled water. An alcoholometer can then be used to determine the concentration.
A good quality thermometer and an alcohol temperature correction table is also required to obtain accurate readings. The tables form the bulk of AS2371, but tables can also be found on the net.
Our Iso Propyl Alcoholometers are widely used in the print industry to accurately determine the concentration of IPA in printing ink. These alcoholometers have a range of 0-20% and are calibrated at 10°C, which is a common temperature for refrigerated printing equipment.
Carlton manufactures a large range of general purpose Brix hydrometers. They are widely used in the sugar industry and other areas where accurate sugar determination is required.
These L50 Density hydrometers conform to ISO649 and BS718, and are calibrated at 20°C specifically for use in the petroleum industry. They come with a Certificate of Conformity and are made by Carlton in Australia.
These L50SP Density hydrometers conform to ISO649 and BS718, and are calibrated at 15°C specifically for use in the petroleum industry (Designated SP or Special Purpose for Petroleum). They come with a Certificate of Conformity and are made by Carlton in Australia.
Our M100 Density hydrometers conform to ISO649 and BS718, and are calibrated at 20°C. They come with a Certificate of Conformity and are made by Carlton in Australia.
