HygroTrac, developed by Dri-Eaz Products and GE Sensing, actively measures relative humidity, air temperature, moisture content and GPP, and transmits this information in real time to a secure web site for review, reporting, and archiving. Data is collected and uploaded every few minutes, providing an unprecedented view of drying progress. Users can set up automatic alarms for multiple parameters. If a reading exceeds or falls below a specified level, then the system will immediately transmit an e-mail or a text message.
