Radiation Temperature Laboratory
About Us
The main objective of the laboratory is to establish, maintain and disseminate the National Radiation Temperature Scale at the primary level. It also ensures the traceability of radiation and contact temperatures to SI units for temperature measurements above 961.78 °C.
Radiation temperature is obtained by measuring the thermal radiation emitted by an object and is preferred for measuring high temperatures thanks to its non-contact measurement capability. It plays a critical role in areas such as metal processing, glass and cement production, food industry, human body temperature measurements, defense industry, climate and environmental observations.
Laboratory;
Devices such as radiation thermometers, thermal cameras, medical non-contact thermometers and pyrometers,
It has the capability to perform calibrations of heat sources such as ovens, black bodies, IR calibrators, etc. traceable to the ITS-90 temperature scale.
It also supports measurement reliability by participating in national and international comparisons. The laboratory is a member of technical committees such as BIPM, EURAMET, COOMET, GULFMET and SMIIC.

One of the first reactions of COVID-19 disease in the human body is an increase in body temperature (fever) by % 80. One of the objectives of this project is to develop a new generation of reference sources and new measurement methods for the calibration of non-contact thermometers, which are widely used for in-vivo measurements of human body temperature (in-vivo) in the public health protection and pre-diagnosis phase. Nowadays, there is a high demand for systems that can detect pathogenic biological agents such as viruses and bacteria, especially in small quantities, for use in public spaces (such as airports). On the other hand, biological weapons are also candidates for use in future terrorist attacks due to the rapid transmission potential of a small amount of biological agents. In this context, the second objective of this project is to develop systems for real-time detection of nanometer-sized viruses, bacteria, etc. in liquids or aerosols using optical methods and to investigate the spectral properties of these objects.
