The Laboratory of Humidity Standards of the Hellenic Institute of Metrology (EIM) is responsible for maintaining and developing the national standards of Greece in the field of humidity since 1999. It is located in building A of the Institute in the same lab area of temperature laboratory.

It is divided into two sections, a primary standards laboratory responsible for calibrating optical dew point hygrometers against our dew point generator and a comparison calibration laboratory responsible for calibrating various types of humidity sensors in a test chamber of controlled temperature and relative humidity.

Tasks of the Laboratory

• To develop and maintain the national standards of Greece in the field of humidity
• To offer calibration services in private metrology laboratories, independent public or private institutions and companies
• To issue calibration certificates for the humidity measuring instruments calibrated in the laboratory
• To offer consultancy services and training to anyone interested in the field of humidity calibration and measurement
