Description
Alcoholometer Class III according to DIN 12803 for the range 70–75 %vol., with a scale division of 0,1 %vol. and accuracy of ±1 scale division, is a precision hydrometer for determining alcohol content by volume. The instrument is 330 mm long and is referenced to 20 °C. It incorporates a thermometer spanning +5 to +25 °C with 0,2 °C division and red or blue special filling, enabling temperature observation during measurement. Reading is taken at the lower meniscus, and the unit is calibratable for controlled laboratory workflows. This alcoholometer from manufacturer Amarell supports routine alcoholometry where Class III performance and a fine 0,1 %vol. interval are required within the upper concentration band. The combined alcohol and temperature scales allow practical on-site assessment of high-percentage samples without separate thermometry. Supplied as one piece, it is suited to quality control, production monitoring and analytical laboratories that work to DIN 12803. Clear scale layout and defined tolerance help maintain consistent volumetric alcohol readings across repeated determinations in the stated range.
This article is part of pH meters, in pH & electrochemistry.

Questions about Alcoholometer, class III, DIN 12803, 70-75:0,1%vol., accuracy +/- 1 scale
What is this article?
Alcoholometer, class III, DIN 12803, 70-75:0,1%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.
