Description
Hydrometer according to Twaddell covering 48–74 °Twaddell is a precision glass densimeter for laboratory and process density measurements expressed in degrees Twaddell. The scale is graduated in 0,5 °Twaddell steps with an accuracy of ± 1 scale division, enabling dependable specific-gravity work on denser aqueous and industrial liquids. Overall length is 240 mm; the instrument is referenced to 60 °F, supplied without a thermometer and intended for bottom meniscus reading. This Twaddell hydrometer from manufacturer Amarell supports quality control, batch release and routine monitoring where the Twaddell scale is the established unit. The 240 mm format is convenient for standard cylinders and everyday bench use. Delivered as one piece, it offers a clear, dedicated measuring range for applications that fall between the mid and higher Twaddell intervals without integrated temperature indication.
This article is part of Hydrometers, in Density & viscosity measurement.

Questions about Hydrometer according to Twaddell, 48-74:0,5°Twaddell, accuracy +/- 1 scale
What is this article?
Hydrometer according to Twaddell, 48-74:0,5°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.
