Description
Hydrometer ASTM 137H-62 covering the specific gravity range 1,600 – 1,650 without an integrated thermometer is a precision glass instrument designed for density determination of liquids in laboratory and industrial settings. The scale is graduated in increments of 0,001 specific gravity units and the overall length is approximately 270 mm, providing a practical balance between readability and ease of handling in standard hydrometer cylinders. Calibration follows the ASTM 137H-62 specification at a reference temperature of 60/60 °F, ensuring consistency with established measurement practice. Manufactured by Geco-Gering, this hydrometer is intended for applications where temperature is measured separately or controlled externally, allowing flexible use with independent thermometers or thermostatic baths. Typical uses include quality control of concentrated solutions, heavy process liquids and specialty chemical samples that fall within the upper specific-gravity band. The absence of a built-in thermometer keeps the construction straightforward while the fine 0,001 division supports accurate visual readings. Supplied as one piece, the instrument fits routine analytical workflows that rely on ASTM-type specific-gravity hydrometers for reliable density assessment.

Questions about Hydrometer ASTM 137H-62 1,600 - 1,650 without thermometer
What is this article?
Hydrometer ASTM 137H-62 1,600 - 1,650 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.
