PERFORMANCE STUDY AND THERMAL PROFILE CHARACTERIZATION OF LOW TEMPERATURE VISCOSITY BATH IN DIFFERENT TEMPERATURE RANGES
H.M. Abu-Dorra; Mohy, E.; Mekkawy, M. M;
Abstract
A new Viscosity bath has been entered the services in Thermal Metrology Laboratory-National
Institute for Standards, NIS-Egypt in order to use in maintain and extend the national viscosity
scale in wide temperature ranges, international comparison and routine calibration of viscometers.
The medium of the bath should be homogenous enough in temperature so many thermal factors
taken into account to estimate the temperature gradient, homogeneity, stability and thermal
profile distribution with the related uncertainty to each parameter. The study carried out by two
Standards Platinum Resistance Thermometer (SPRT) calibrated at fixed point according to
ITS-90.
