Description
Density hydrometer type L20-070 is a precision glass instrument for determining liquid density across the range 0,7000–0,7200 g/cm³. Conforming to DIN 12791 and similar to BS 718, it features a scale division of 0,0002 g/cm³ and an accuracy of ±1 scale division, enabling finely resolved density readings on light to medium-density liquids. The hydrometer measures 430 mm in length, is adjusted to a reference temperature of 20 °C, is supplied without a thermometer, and is read at the bottom of the meniscus once floating equilibrium is reached. It is calibratable for laboratories that require traceable verification of density glassware. Manufactured by Amarell and offered as a single piece, this model complements adjacent L20-series ranges where continuous coverage near 0,70–0,72 g/cm³ is needed. The extended stem supports clear scale observation and stable immersion behaviour, while the thermometer-free design keeps the focus on density indication under externally controlled temperature conditions. It is well suited to analytical, quality-control and process applications that demand narrow-range density measurement at the stated 20 °C reference.

Questions about Density hydrometer, type L20-070, DIN 12791/similar to BS 718,
What is this article?
Density hydrometer, type L20-070, DIN 12791/similar to BS 718, 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.
