Description
Alcoholometer, Richter and Tralles type, 0-100:1, is a glass hydrometer designed for alcohol content determination according to the Richter and Tralles scales. The instrument measures from 0 to 100 with a scale division of 1 and an accuracy of ± 1 scale division. It is 280 mm long and referenced to 20 °C. An integrated thermometer covers 0 to +40 °C in 1 °C steps and is filled with red or blue special liquid; readings are taken at the lower meniscus. This single-piece unit from manufacturer Amarell supports classical alcoholometry in laboratories and production settings that specify Richter–Tralles graduation. The combination of a full 0–100 range, clear 1-unit division and on-board temperature indication enables consistent density-based assessment of aqueous ethanol mixtures. Its 280 mm format and bottom-reading layout suit routine analytical workflows where reliable, temperature-aware alcohol measurement is required.
This article is part of Hydrometers, in Density & viscosity measurement.

What is this article?
Alcoholometer, type Richter and Tralles, 0-100:1, accuracy +/- 1 scale division, is the article on this page. Luminix Health distributes Amarell for laboratory use. It sits in Hydrometers, inside Density & viscosity measurement, in Lab instruments.
A hydrometer floats in a liquid and the stem reading is the density or a related scale such as Brix. The liquid has to be at the temperature printed on the stem, or a correction is required. A chip on the stem changes the reading. One hydrometer does not cover every density.
Density is mass divided by volume. A hydrometer floats at a depth that depends on the density of the liquid. A pycnometer is a vessel of known volume that is weighed full. Viscosity is the resistance to flow. A capillary viscometer times how long a volume takes to fall through a tube. Both measurements need a stated temperature, because liquids change density and viscosity as they warm. The units trace to the BIPM and to NIST.
