Precise thermal measurements in all their branches are among the key applications in the field of metrology, significantly impacting our daily lives. These measurements are widely conducted in laboratories, factories, military, health, and civil sectors at various levels. To meet these diverse needs, the management has focused on establishing national standards for temperature measurement and providing calibration services for service and production sectors in Saudi Arabia. The Thermal Measurements Management consists of three main laboratories: Thermal Conductivity Laboratory, Humidity Laboratory, and Thermal Radiation Laboratory.
The Thermal Conductivity Laboratory is an essential part of the Thermal Measurements Management at the National Center for Measurement and Calibration, where it calibrates all heat scales using the dynamic temperature unit (Kelvin). Additionally, the laboratory is responsible for achieving the International Temperature Scale of 1990 (ITS-90) and maintaining its accuracy through the use of fixed cells and Standard Platinum Resistance Thermometers (SPRT). Subsequently, these calibrations are transferred to all national entities that measure temperatures in industries and services. The laboratory provides calibration services for all temperature measurement devices and thermal environments using high-precision reference instruments and possesses high-level measurement capabilities as follows:

The Humidity Laboratory plays a vital role in the field of humidity measurement, where it works on establishing and preserving measurement standards in this domain. Humidity is considered one of the most significant climatic factors that impact our daily lives, varying according to temperature and air pressure. The laboratory employs various methods to measure humidity using different devices, ensuring their precise calibration and alignment with international standards. Additionally, the laboratory provides calibration services for high-precision measurement devices, such as dew point and relative humidity meters, in addition to air thermometers. The laboratory possesses advanced measurement capabilities that contribute to achieving high accuracy in results, as follows:
Calibration and Measurement Capabilities:
The Thermal Radiation Laboratory is responsible for establishing and maintaining national measurement standards for thermodynamic heat quantity, which is measured in Kelvin units, using the phenomenon of thermal radiation heat transfer. Thermal radiation is considered a form of energy transfer, where heat is transferred from one place to another through electromagnetic waves without the need for a material medium. The laboratory provides calibration services for high-precision temperature measurement devices, such as thermal radiation thermometers, black body devices, and thermal radiation cameras. The laboratory possesses advanced measurement capabilities that ensure the accuracy and reliability of results, as follows:
