Temperature Measurement Methods and Calibration Unit
Temperature Measurement Methods and Calibration Unit for Science Lab Equipment Laboratory Instruments Manufacturers, Engineering Lab Equipments Manufacturers

The measurement of temperature is fundamental to almost every branch of engineering and science. The Temperature Measurement Methods and Calibration Unit enables students to investigate the many different methods of measuring temperature and to determine the advantages and disadvantages of the various sensor and indicator types. Up to nine different methods of Temperature Measurement Methods and Calibration Unit are included and students undertake detailed experiments to compare not only accuracy but also the way in which the instruments work. The operation of platinum resistance temperature sensors and their importance in the International Temperature Scale are investigated.
