Description
Density hydrometer type 3 is a laboratory instrument for determining liquid density over the range 0,820–0,880 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 comparable readings under standard calibration conditions. An integrated thermometer spans 0 to +40 °C in 1 °C steps and uses a red or blue special filling for clear temperature observation during immersion. Scale values are read at the lower meniscus, supporting consistent density assessment in routine analytical work. Offered as a single piece from manufacturer Amarell, this type 3 hydrometer suits quality-control and research settings where solvents, organic liquids or process media fall within the graduated window. Successive type designations in the series cover adjacent density intervals, so laboratories can match the instrument to the expected sample range. The combination of narrow scale division, defined reference temperature and built-in thermometer makes the device practical for precise density checks without separate temperature correction tools when working near 20 °C.

What is this article?
Density hydrometer, type 3, 0,820-0,880:0,001g/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.
