Description
Baumé hydrometer 20-40:1/1 °Bé is a laboratory density instrument covering the mid-range Baumé scale from 20 to 40 °Baumé. Scale division is 1/1 °Baumé, and stated accuracy is ±1 scale division, supporting reliable comparative measurements. The stem length is 240 mm, suitable for immersion in common measuring cylinders. Reference temperature is 15 °C, aligning readings with a defined calibration condition. The unit is supplied without a built-in thermometer and uses bottom reading of the liquid meniscus. Manufactured by Amarell, this hydrometer is intended for density assessment of denser aqueous solutions, process liquors, and industrial fluids where Baumé values are required. Clear graduation and defined accuracy help operators track concentration trends in quality control, production, and teaching laboratories. Single-piece glass construction keeps handling simple and the scale easy to observe. Supplied as one piece for direct laboratory deployment.

What is this article?
Hydrometer according to Baumé, 20-40:1/1°Bé, 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.
