Description
Hydrometer according to Twaddell spanning 48–74 °Twaddell with a scale division of 1 °Twaddell and accuracy of ± 1 scale division supports density measurements expressed in Twaddell degrees. The instrument is 150 mm long and is referenced to 60 °F. It is supplied without a thermometer and is intended for bottom reading of the scale. This model from manufacturer Amarell presents a continuous scale from start value 48 to end value 74 in uniform 1 °Twaddell steps. The 150 mm length allows practical immersion while the graduated stem remains readable. Bottom reading facilitates observation of the liquid level against the scale markings. Because no thermometer is integrated, the sample should be brought to the 60 °F reference temperature before a reading is taken. Accuracy of ± 1 scale division matches the stated scale division, defining both resolution and tolerance across the full interval. Supplied as 1 piece, the hydrometer is suited to laboratory and process density checks that specify the Twaddell scale within 48–74 °Twaddell. Clear scale progression and compact format support routine handling and consistent interpretation of results under the given reference condition.
This article is part of Hydrometers, in Density & viscosity measurement.

Questions about Hydrometer according to Twaddell, 48-74:1°Twaddell, accuracy +/- 1 scale
What is this article?
Hydrometer according to Twaddell, 48-74:1°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.
