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 that will hold its calibration.  RS232 output enables the logging of data over a period with an optional separate RS232 logging device and matching PC software. The unit has max, min, and holds functions and measures in different models, CO₂, RH, and temperature.
