The AQ100 and AQ200 are IAQ meters. The AQ100 is an economical, fixed probe, hand-held air quality sensor for ambient temperature and CO2 measurement. It uses nondispersive infrared (NDIR) technology and comes with a soft carrying case. The AQ200 has interchangeable measurement modules, as opposed to a fixed probe, and according to the manufacturer, is available in popular kits with temperature/CO2/humidity or temperature/CO2/humidity/CO, for example. The AQ200 also comes standard with a voltage/current module (0-10V, 4-20 mA), two Pt100 channels, and a PC output with software. Features of the two meters include selection of units, minimum/maximum and hold functions, automatic shutoff, and adjustable backlight. They are supplied with a calibration certification.
