Webbwhether a thermometer is showing a temperature of 24.0°C, 24.5°C or 25.0°C; exactly when a chemical reaction has finished; There are two ways of estimating uncertainty: WebbThermowells are used to guard temperature sensors such as thermocouples, thermistors and bimetal thermometers against damage from excessive pressure, material velocity and corrosion. They also increase the longevity of the sensor, allow sensor replacement without draining the system and reduce the probability of contamination.
