Description
Hydrometer 0,750–0,840 with WG thermometer –10+60 °C is a precision density instrument developed for opaque mineral oils. It measures density over the range 0,750 to 0,840 g/cm³ with a scale division of 0,001 g/cm³ and is referenced to 15 °C. The integrated thermometer covers –10 to +60 °C, allowing concurrent temperature monitoring during immersion and supporting reliable density evaluation of dark or non-transparent samples. Approximately 400 mm in length, the glass hydrometer offers a clear, practical scale for laboratory and industrial quality-control work. Supplied as a single piece from manufacturer Geco-Gering, the instrument is suited to petrochemical, lubricant and process laboratories that routinely determine the specific gravity of opaque mineral-oil products. Its combination of narrow density span, fine graduation and built-in temperature indication provides operators with the essential data needed for consistent sample characterisation under typical working conditions.

Questions about Hydrometer 0,750 - 0,840 with WG-therm.-10+60°C
What is this article?
Hydrometer 0,750 - 0,840 with WG-therm.-10+60°C 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.
