Description
Hydrometer 0,640 - 0,660 without thermometer is a precision density measuring instrument for laboratory determination of specific gravity in the stated range. Built to DIN 12791 Series L20, this glass hydrometer is approximately 420 mm long and is graduated in fine steps of 0,0002 g/cm³, enabling detailed density readings at a reference temperature of 20 °C. The instrument is supplied without an integrated thermometer, making it suitable where temperature is controlled separately or measured with an external probe. Typical applications include quality control, process monitoring and analytical laboratories that require reliable density checks on liquids within the 0,640–0,660 g/cm³ window. Available from manufacturer Geco-Gering, the hydrometer is offered as a single piece for flexible laboratory stocking. Its clear scale division and standardised Series L20 construction support reproducible measurements in research, industrial and educational settings. Users working with low-density liquids will appreciate the fine graduation and the defined reference temperature, which together facilitate consistent density determination according to established laboratory practice for DIN 12791 hydrometers.
This article is part of Hydrometers, in Density & viscosity measurement.

Questions about Hydrometer 0,640 - 0,660 without thermometer
What is this article?
Hydrometer 0,640 - 0,660 without thermometer is the article on this page. Luminix Health distributes Geco-Gering 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.
