The AirTest™ Personal Air Quality Monitor measures carbon dioxide, humidity, and temperature, displaying the results on a large LCD screen. Date and time are also displayed. The display interprets the indoor carbon dioxide readings and indicates if ventilation rates are “good,” “normal” or “poor.” Designed as a very affordable, plug-in monitor, it is ideal for the home or workplace, says the manufacturer. The monitor requires no maintenance or calibration and uses advanced sensor technology previously only available in professional air quality diagnostic equipment, the company says.
