How it works
The Teledyne API CO Gas Filter Correlation Analyser (Model N300) uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapour) that also absorb IR. The analyser passes the IR beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure.
Intuitive operation and calibration of all N Series products is achieved through the NumaView™ Software interface.
