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.
Technology is advancing at a fast pace in our ever-changing water damage restoration industry. However, even with these innovative changes, moisture content measurement will always remain a critical component.
Wagner Meters has released a free firmware update for its Rapid RH DataMaster, its pocket-sized Bluethooth-enabled device that uses a touch screen interface to detect moisture in concrete applications.
