What is an ASTM Thermometer?
An ASTM thermometer must conform to all accuracy tolerance and dimensional specifications of the American Society for Testing and Materials. The ASTM's Committee on Temperature Measurement (E-20) meets annually to examine and, if necessary, revise/add/delete the specification for each of the ASTM thermometers. All of the ASTM thermometers are fully described in Brooklyn Thermometer's current Catalogue, available FREE upon request.
A Laboratory Grade Thermometer measures temperature in 0.5, 1, 2, or 5° divisions. A Precision Grade Thermometer should be used when 0.05, 0.1, 0.2, or 0.5° divisions are required. Brooklyn Thermometer manufactures the largest stocked selection, with over 110 Laboratory and 270 Precision Grade thermometers; plus, all our ASTM, Calorimeter, Maximum Registering and Red Liquid filled thermometers.
