Temperature measurement in everyday life

Temperature is the most frequently measured measurand in everyday life as well as in industry and research. Temperature measurements are indispensable in areas such as medicine, the food industry, the electronics industry and meteorology. Temperature is used in all areas as a key measurand for monitoring, controlling, optimising and observing processes and phenomena.

At METAS, we ensure the traceability of thermal measurands to the International System of Units (SI) and make them available to business, research and administration as well as to verification offices and verification laboratories.

Typical applications of temperature measurement

Temperature measurement is used in many different fields and circumstances:

• Industry: in production and testing processes
• Energy sector: power plants and building materials
• Biology and medicine: for laboratory analyses and patient monitoring
• Meteorology and climatology: for weather observation and in climate studies
• Research and laboratory tests: as a control variable
• Chemistry and process engineering: as a control and process variable
• Building and air-conditioning technology: as a control and process variable

Our services in the field of temperature

In the field of temperature, we offer the following calibration services:

• Calibration of resistance thermometers at fixed points (-189°C to 660°C)
• Calibration of resistance thermometers and thermocouples (-196°C to 660°C)
• Calibration of temperature measuring instruments with displays using the comparative method (-196°C / -90°C to 660°C)
• Calibration of block calibrators (-100°C to 660°C)

Is the service you are looking for not listed on the website? Please do not hesitate to contact us so that we can work together to find a customised solution to your problem.

Measuring methods and technologies

To ensure traceability to the SI, we implement the International Temperature Scale of 1990 (ITS-90). This is done in the temperature range of -189°C to 660°C using temperature fixed points (melting, solidification and triple points) of high-purity substances. These serve as a reference for the calibration of thermometers and enable reproducible, stable and thus internationally comparable temperature measurements.
