Description
Hydrometer according to Twaddell for the range 72–104 °Twaddell is a glass density measuring instrument for higher-density liquids assessed on the Twaddell scale. It provides a scale division of 0,5 °Twaddell and an accuracy of ± 1 scale division, suitable for laboratory and industrial specific-gravity determinations. The body is 240 mm long, calibrated at a reference temperature of 60 °F, supplied without thermometer and designed for bottom meniscus reading to maintain uniform observation practice. This Twaddell hydrometer from manufacturer Amarell is appropriate for quality control, process checks and routine density work where elevated Twaddell values are required. Its compact 240 mm length fits common hydrometer cylinders and supports easy handling at the bench. Packaged as a single piece, it delivers a focused high-range tool for applications that need clear Twaddell graduations without built-in temperature compensation.
This article is part of Hydrometers, in Density & viscosity measurement.

Questions about Hydrometer according to Twaddell, 72-104:0,5°Twaddell, accuracy +/- 1 scale
What is this article?
Hydrometer according to Twaddell, 72-104:0,5°Twaddell, accuracy +/- 1 scale is the article on this page. Luminix Health distributes Amarell 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.
