Hydrometer ASTM 90H 1,050-1,100:0,0005 is a laboratory hydrometer for specific gravity measurement in the range 1,050 to 1,100 with a fine scale division of 0,0005. The ASTM 90H type is selected when liquids sit above unity and a tighter graduation is required for more detailed reading within that band. Compared with coarser 0,005 scales on neighbouring ASTM hydrometers, the 0,0005 division supports higher resolution observation during immersion tests in quality control, formulation and analytical settings. Supplied as 1 pc, the instrument has a net weight of 0,094 kg and a gross weight of 0,094 kg. Laboratories use the ASTM 90H window whenever sample specific gravity falls between 1,050 and 1,100 and the workflow calls for the finer printed interval. This hydrometer from manufacturer Witeg complements other ASTM models that span adjacent specific-gravity ranges, helping users keep a coherent set of instruments across density bands. Origin is Germany. It is intended for professional laboratory environments that specify ASTM hydrometers for repeatable specific gravity work inside the stated 1,050–1,100 limits.
This article is part of Hydrometers, in Density & viscosity measurement.

Questions about Areometer ASTM 90H 1,050-1,100:0,0005
What is this article?
Areometer ASTM 90H 1,050-1,100:0,0005 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Hydrometers, inside Density & viscosity measurement, in Instrumenten.
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.
