The Lutron GC-2028 and GCH-2018 are low cost CO2 indicators for environmental applications. These are usually in the 0-2000ppm range. Lutron has used NDIR for measurement  which results in a stable and accurate device which will hold its calibration.  An RS232 output enables logging of data over a period with an optional separate RS232 logging device and matching PC software. The unit has max, min and hold functions and measures in different models, CO2, RH and temperature.
