Description
Hydrometer 0,720–0,740 without thermometer is a precision laboratory instrument for determining liquid density within a narrow measuring range. Built to DIN 12791 Series L20 specifications, it covers densities from 0,720 to 0,740 g/cm³ and features a fine scale division of 0,0002 g/cm³ for high-resolution readings. The instrument measures approximately 420 mm in length and is calibrated at a reference temperature of 20 °C. Supplied without an integrated thermometer, it is intended for use where temperature is controlled or measured separately. This hydrometer from manufacturer Geco-Gering supports density determinations in quality control, research and analytical laboratories that require reliable glassware conforming to established standards. The single-piece unit is suited to routine work with liquids whose densities fall in the specified interval. Clear graduation and the L20 series format facilitate straightforward handling and reading. Laboratories seeking a dedicated density instrument for this range will find a practical tool that aligns with DIN 12791 requirements for Series L20 hydrometers without thermometer.

Questions about Hydrometer 0,720 - 0,740 without thermometer
What is this article?
Hydrometer 0,720 - 0,740 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.
