Description
Hydrometer ASTM 7H-62 59 - 71 without thermometer is an A.P.I. gravity hydrometer intended for accurate density measurement of petroleum products and similar liquids. It spans the range 59 to 71 °API with 0,1 °API scale divisions and is referenced to 60 °F. The instrument measures approximately 330 mm in length, offering good scale visibility for laboratory and process-control work. Delivered without a built-in thermometer, this hydrometer from manufacturer Geco-Gering is used together with independent temperature measurement in accordance with ASTM practice. Clear glass construction ensures reliable buoyancy readings for quality assurance and research applications. Ideal for petroleum testing laboratories, refineries and industrial facilities that require consistent A.P.I. gravity data. Each unit is supplied as a single piece prepared for verification and routine analytical use.
This article is part of Hydrometers, in Density & viscosity measurement.

Questions about Hydrometer ASTM 7H-62 59 - 71 without thermometer
What is this article?
Hydrometer ASTM 7H-62 59 - 71 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 Instruments de laboratoire.
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.
Which category should I open next?
The category is Density & viscosity measurement. The sub-category is Hydrometers. The catalogue is Instruments de laboratoire.
