Measuring humidity accurately with long term repeatability has always been a significant challenge for sensor companies. At the core of that challenge is a good reference measurement from which to calibrate all sensors. Humidity chambers mix dry air and water vapor to create atmosphere and often this is further improved with an instrument like a chilled mirror dew point sensor.
Each half-day seminar will detail the changes that affect the way materials are now recommended to be dried, calculations for dehumidification, air movement, application of heat, and science that includes vapor pressure of materials.
