Menetelmä ja laitteisto suhteellisen pitoisuuden mittauksen kalibroimiseksi

摘要

The invention relates to a method for calibrating the relative content (RH) of water. According to the invention, at least one calibration point is defined at a known partial pressure (Pw) of water vapour and sensor temperature of the sensor. According to the invention, at the same known partial pressure (Pw) of water the sensor (2) is heated and, at least one increased temperature point, both the relative content (RH) and the temperature (T) are measured simultaneously.
