Description
Alcoholometer Class III according to DIN 12803 covering the 90–95 %vol. range with 0,1 %vol. scale division and accuracy of ±1 scale division is a glass hydrometer for alcohol content determination by volume. The instrument is 330 mm long and referenced to 20 °C, ensuring consistent alcoholometric readings under defined temperature conditions. It includes an integrated thermometer spanning +5 to +25 °C with 0,2 °C division and red or blue special filling for clear temperature indication during use. Bottom reading supports straightforward meniscus observation, and the design is calibratable for metrological control. Offered as a single piece from manufacturer Amarell, this alcoholometer suits laboratory, production and quality-control environments that require reliable measurement in the upper alcohol concentration interval. Class III performance under DIN 12803 defines the accuracy class for this type of alcoholometer. The combined alcohol and temperature scales allow density-related alcohol determination with simultaneous temperature compensation within the stated working window, supporting routine analytical workflows where high-percentage alcohol solutions are assessed.
This article is part of pH meters, in pH & electrochemistry.

Questions about Alcoholometer, class III, DIN 12803, 90-95:0,1%vol., accuracy +/- 1 scale
What is this article?
Alcoholometer, class III, DIN 12803, 90-95:0,1%vol., accuracy +/- 1 scale is the article on this page. Luminix Health distributes Amarell for laboratory use. It sits in pH meters, inside pH & electrochemistry, in Instruments de laboratoire.
A pH meter reads the electrode and displays pH, after calibration with at least two buffers. A meter that cannot be calibrated is a voltmeter. Resolution to 0.001 is not the same as accuracy. Portable and benchtop meters differ in the electrodes they accept and in the data they store.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
