Research on procedure to assure the continued validity of the verification results of standard mercury-in-glass thermometer (grade I) / 生物医学工程学杂志

ABSTRACT

Standard mercury-in-glass thermometer (Grade I) can be used to perform traceable measurements. Full recalibration is necessary to assure the continued validity of the verification results of the standard mercury-in-glass thermometer (Grade I). The present paper shows researches on procedure for the recalibration at the ice point of standard mercury-in-glass thermometer (Grade I), and points out different calculation ways of the true temperature of the thermostatic bath. The different values of scale correction and adjusted scale correction are compared in this paper.
