Chris Ranwell is the Global Product Manager for the gas and moisture products at Amphenol Advanced Sensors, including Protimeter. Chris has for the last 21 years been directly involved with use of moisture meters and hygrometers for detecting and diagnosing moisture problems in buildings as well as the use of meters for flood damage restoration. Chris serves on several industry technical committees including ASTM F06 for resilient flooring and is WRT/ASD certified.
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.
