Digital Thermometer vs Mercury Thermometer: Which is ...

16/01/2019· In fact, some digital thermometers also include thermocouple sensors on the probe that have been measured and calculated to provide very high accuracy and without the need for calibration like mercury thermostats. Calibration refers to the measurement that is performed on a thermometer to check the readings. Once the thermometer is tested, it is then adjusted or re-calibrated so that it ...

Comparing Thermocouples and RTDs (Resistance Temperature ...

When an RTD is made of platinum, it is sometimes referred to as a platinum resistance thermometer (PRT). Platinum is known as an industry standard in RTDs because it provides the widest temperature range, longest stability and highest accuracy. As the temperature varies, it produces a change in resistance. This change is used to determine temperature. Due to their high accuracy and stability ...

What is a Thermocouple? How does it work? What is it's ...

A thermocouple measures temperature, so technically, a thermocouple is a type of thermometer. Of course, not all thermometers are the same. Two different metals make up a thermocouple. Generally, in the form of two wires twisted, welded, or crimped together. Temperature is sensed by measuring the voltage. Heating a metal wire will cause electrons within the wire to get excited and want to move ...
