The Lutron GC-2028 and GCH-2018 are low cost CO2hand held 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. It is available with optional RH and Temperature to 4000ppm.
