Glass Mercury Thermometer 305mm – Overview

These thermometers are made from the highest quality lead, normal or borosilicate glass specially selected to have a uniform capillary bore and to be free from strain. Instruments are scientifically annealed and artificially aged before calibration to ensure stability and maintain accuracy. Top expansion chambers are provided where necessary to allow for overheating and to facilitate the rejoining of the spirit or mercury column should it become separated in transit or use. Mercury Thermometers have pressurised nitrogen gas above the column to ensure reliable readings at the lowest temperatures on the scale. Scales on the thermometers have permanently marked graduations, figures and naming. Each instrument is fitted with an anti-roll cap and packed in a protective plastic container
