    INTRODUCTION, SPECIFICATIONS, APPROVALS, & COMPLIANCE The Teledyne API Models N360 and N360M differ only in specifications; unless clearly differentiated, both models in this manual are referred to as the N360 for simplification. The N360/N360M measures carbon dioxide CO by comparing infrared energy absorbed by a sample to that absorbed by a reference according to the Beer-Lambert law.

    This valve option is intended for applications where zero air and span gas are supplied by a zero air generator and gas dilution calibrator such as those in the Teledyne API 700- Series. Internal zero/span and sample/cal valves control the flow of gas through the instrument, but because the calibrator limits the flow of span gas no shutoff valve is required.

  • Page 119: Theory Of Operation

    THEORY OF OPERATION The Model N360 Gas Filter Correlation Carbon Dioxide Analyzer is a microprocessor- controlled analyzer that determines the concentration of carbon dioxide (CO ) in a sample gas drawn through the instrument. It requires that the sample and calibration gases be supplied at ambient atmospheric pressure in order to establish a stable gas flow through the sample chamber where the gases ability to absorb infrared radiation is measured.
