The Model 300E Gas Filter Correlation Carbon Monoxide Analyzer is at its heart a
high performance, 386-based microcomputer running MS-DOS. Inside the DOS

various interfaces, performs procedures and tasks, stores data in the CPU's various
memory devices and calculates the concentration of the sample gas.
