Description
Alcoholometer Class III according to DIN 12803 is a glass hydrometer for determining alcohol content in the high range from 98 to 103 %vol. with a fine scale division of 0,1 %vol. and stated accuracy of ±1 scale division. The instrument measures 330 mm in length and is referenced to 20 °C, ensuring consistent readings under standard laboratory conditions. It incorporates an integrated thermometer covering +5 to +25 °C with 0,2 °C division and red or blue special filling, allowing simultaneous temperature observation. Bottom reading supports clear meniscus assessment during use. Suitable for quality control, spirits analysis and laboratory alcoholometry where Class III performance and calibratability are required, this model from manufacturer Amarell provides a practical combination of alcohol and temperature scales in one unit. The design supports routine volumetric alcohol determination in research, production and testing environments that follow DIN 12803 conventions for Class III alcoholometers.
This article is part of pH meters, in pH & electrochemistry.

Questions about Alcoholometer, class III, DIN 12803, 98-103:0,1%vol., accuracy +/- 1 scale
What is this article?
Alcoholometer, class III, DIN 12803, 98-103:0,1%vol., accuracy +/- 1 scale is the article on this page. Luminix Health distributes Amarell for laboratory use. It sits in pH-mètres, inside pH & électrochimie, 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.
