Description
Hydrometer ASTM 2H-62 9 to 21 without thermometer is an A.P.I. gravity hydrometer intended for relative-density determination of petroleum liquids according to ASTM practice. The instrument spans the measuring range from 9 to 21 °API and is graduated in 0,1 °API increments, enabling precise stepwise readings over its working interval. Approximately 330 mm in length, it fits standard hydrometer cylinders used in laboratory and industrial density testing. Calibration is referenced to 60 °F, consistent with widely applied petroleum measurement conventions. This hydrometer from manufacturer Geco-Gering is supplied without a built-in thermometer, allowing temperature correction to be handled separately where required by the analytical method. It is suited to quality assurance, product characterisation and process monitoring of petroleum fractions and related fluids that fall within the 9 to 21 °API window. Clear scale division and a well-defined range support repeatable API gravity measurements in routine workflows. The unit is offered as a single piece for straightforward integration into existing laboratory procedures.
This article is part of Hydrometers, in Density & viscosity measurement.

Questions about Hydrometer ASTM 2H-62 9 - 21 without thermometer
What is this article?
Hydrometer ASTM 2H-62 9 - 21 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.
