Description
Hydrometer ASTM 8H-62 69 - 81 without thermometer is an A.P.I. gravity hydrometer for determining API gravity of petroleum products and related liquids. It covers the measuring range 69 – 81 °API and is graduated in 0,1 °API increments for clear, reproducible scale readings. The instrument is approximately 330 mm long and is supplied without an integrated thermometer, so temperature can be recorded separately when required by the method. Reference temperature is 60 °F in accordance with the ASTM designation for this series. This model from manufacturer Geco-Gering is intended for laboratory and industrial quality-control work where standardized API gravity values are needed. The compact length suits common hydrometer cylinders and sample jars used in fuel and refining analysis. Offered as a single piece, it is ready for routine density-related measurements that call for the ASTM 8H-62 range and scale format. Consistent graduation and the defined reference temperature support alignment with established A.P.I. gravity procedures across successive batches and operators.
This article is part of Hydrometers, in Density & viscosity measurement.

Questions about Hydrometer ASTM 8H-62 69 - 81 without thermometer
What is this article?
Hydrometer ASTM 8H-62 69 - 81 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.
