Temperature Calibration Baths

Temperature Calibration Baths are constant temperature sources that provide heating or cooling of a liquid to provide more precise calibration of temperature sensors such as resistance thermometer temperature sensors (RTD), platinum resistance thermometers (PRT, SPRT), thermocouples. Depending on the temperature to be measured for calibration, temperature calibration baths are filled with either water or certain types of oil. In order to achieve a higher temperature homogeneity, stability and the lowest calibration uncertainties, experts recommend temperature calibration baths instead of dry block calibrators. Calibration baths can be either in the form of portable instruments or large, permanently installed in the laboratory.
