Description
A.P.I. gravity hydrometer ASTM 5H-62 covering the range 39–51 °API is a glass density instrument for petroleum and related liquid measurements without an integrated thermometer. The scale is graduated in 0,1 °API increments and referenced to a standard temperature of 60 °F, supporting consistent API gravity readings in laboratory and quality-control settings. With an approximate length of 330 mm, the hydrometer offers a practical size for routine immersion measurements in suitable cylinders. This instrument from manufacturer Geco-Gering follows the ASTM 5H-62 designation and is intended for applications where API gravity is determined separately from temperature measurement. Supplied as a single piece, it suits fuel, oil and petrochemical laboratories that require a dedicated short-range API hydrometer without a built-in thermometer. Clear 0,1 °API divisions aid readable intermediate values across the 39–51 interval. Use this ASTM hydrometer when a compact, thermometer-free API gravity tool is specified for standardised density assessment of lighter petroleum fractions.
This article is part of Hydrometers, in Density & viscosity measurement.

Questions about Hydrometer ASTM 5H-62 39 - 51 without thermometer
What is this article?
Hydrometer ASTM 5H-62 39 - 51 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.
