The PureTrac® is an Internet-based IAQ monitoring and reporting system that provides continuous, real-time data to schools and commercial buildings, the company says. The system gathers IAQ data through compact Nose® monitors, which house sensors for five elements: temperature, humidity, carbon dioxide, carbon monoxide, and organic odors and gases (O&G). The PureTrac Version 3.2 includes improved calibration stability for the carbon dioxide sensor, and greater range, full-scale capability, and improved baseline stability for the O&G sensor, the manufacturer states. The company says that customers now can select an O&G sensor that focuses either on range or sensitivity.
