Description
Density hydrometer type 18 is a precision laboratory instrument for determining liquid density in the range 1,720–1,780 g/cm³ with a fine scale division of 0,001 g/cm³. The unit is 350 mm long and is referenced to 20 °C, ensuring consistent density readings under standard calibration conditions. An integrated thermometer spans 0 to +40 °C with 1 °C graduation and is filled with red or blue special filling; density values are read at the lower meniscus. Offered as a single piece from manufacturer Amarell, this type 18 hydrometer is suited to routine density checks on high-density liquids in analytical, process and quality-control laboratories. Combining density and temperature indication in one glass body simplifies simultaneous observation during immersion. The clearly graduated scale supports reliable resolution across the stated interval, while the built-in thermometer helps operators account for temperature during measurement. Manufactured in Germany, the instrument is intended for professional laboratory use wherever accurate density determination within this high-density window is required.

What is this article?
Density hydrometer, type 18, 1,720-1,780:0,001g/cm³, 350mm long, reference 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.
