Description
Hydrometer according to Twaddell covering 168–200 °Twaddell at 0,5 °Twaddell scale division is a density measuring instrument for the Twaddell scale. Accuracy is specified as ±1 scale division. The instrument is 300 mm long and referenced to 60 °F. It includes a thermometer from 0 to +40/50 °C with 1 °C division and red or blue special filling; reading is taken at the bottom. This Twaddell hydrometer from manufacturer Amarell enables density determinations across the stated upper Twaddell range with fine scale resolution. The integrated thermometer allows temperature to be observed with the density scale during immersion, supporting interpretation against the 60 °F reference. A 0,5 °Twaddell division between 168 and 200 °Twaddell assists comparative readings in laboratory control work. Delivered as 1 piece, the unit pairs the graduated hydrometer with the built-in thermometer for everyday professional use. Defined range, division, accuracy, length and reference temperature form a clear specification for Twaddell hydrometry where bottom reading and special thermometer filling are required.
This article is part of Hydrometers, in Density & viscosity measurement.

Questions about Hydrometer according to Twaddell, 168-200:0,5°Twaddell, accuracy +/- 1 scale
What is this article?
Hydrometer according to Twaddell, 168-200:0,5°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.
