Description
Hydrometer ASTM 87H 0,900-0,950:0,005 is a precision density instrument for specific-gravity determination across the range 0,900 to 0,950. Its scale is subdivided in steps of 0,005, allowing operators to resolve incremental changes in liquid density during laboratory testing, incoming inspection, or process verification. The ASTM 87H designation situates the hydrometer within a standardised series, which supports consistent reporting and cross-site comparability. Delivered as a single piece with a net weight of 0,059 kg, the unit is convenient for regular use on the analytical bench. Produced by Witeg, it is intended for specific-gravity measurements according to the indicated ASTM scale and range. Typical uses include characterisation of aqueous and organic liquids, educational demonstrations of density, and quality-assurance programmes that call for a narrow measuring window with fine graduation. Clear range limits and the 0,005 division reduce reading uncertainty when samples sit near decision thresholds. Specify this ASTM 87H hydrometer when your methods require specific-gravity data between 0,900 and 0,950 under controlled conditions.

Questions about Areometer ASTM 87H 0,900-0,950:0,005
What is this article?
Areometer ASTM 87H 0,900-0,950:0,005 is the article on this page. Luminix Health distributes Witeg 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.
