Additional Information

Zeal BS 1704 and BS 593 Laboratory Thermometers are quality precision instruments manufactured in

compliance with the relevant standard. Made from the highest quality lead, normal, or borosilicate glass that has a uniform capillary bore and is free from strain. The thermometers are scientifically annealed and artificially aged before calibration to ensure stability and to maintain accuracy. Top expansion chambers are provided where necessary to allow for overheating and to facilitate rejoining of the mercury column should it become separated in transit or use. The triple distilled Mercury fillings have pressurised nitrogen gas above the column to provide reliable readings at the lowest temperatures on the scale. Thermometer scales are engraved into the glass. Each instrument is packed in a protective plastic container.

Anti-roll caps. Supplied as singles
