The Laboratory of Meteorological Device Calibration (LMDC) has been founded in 1996 and operates since at the premises of the Institute for Environmental Research and Sustainable Development (IERSD) at Lofos Koufou in the area of Palea Penteli. The main goal of LMDC is to offer calibration services for meteorological instruments and actinometers to the private and public sector, the provision of education and technical support to the use of meteorological sensors and instrumentation, and finally the provision of consulting services of meteorological equipment.

The LMDC calibrates meteorological instruments such as: thermometers (mostly electronic, while liquid-in-glass thermometers are checked for good operation only), thermographs, hygrometers and hygrographs, pyranometers, photometers and rain gauges. Data collection and processing is performed with high accuracy instruments.
