The water damage restoration industry recognized standard of care, the ANSI/IICRC S500, contains a significant amount of information related to the use of meters during a drying project. The most important content is primarily in two sections; Section 10 Inspections, Preliminary Determination, and Pre-Restoration Evaluations, and Section 13, Structural Restoration.

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.
