  • Page 15: Introduction, Specifications, Approvals, & Compliance

    INTRODUCTION, SPECIFICATIONS, APPROVALS, & COMPLIANCE Teledyne API’s Model N500 CAPS NO -NO Analyzer uses Cavity-Attenuated Phase-Shift (CAPS) spectroscopy to render direct, true measurements of nitrogen dioxide ). By combining direct NO measurements with highly efficient gas phase titration (GPT), the N500 converts and measures the NO sample gas component as NO , thus allowing for the measurement of total NOx.

    1. Verify that the expected concentration is set properly to the actual span gas concentration in the CONC sub-menu. 2. Confirm that the NO span gas source is accurate. • This can be done by comparing the source with another calibrated analyzer. Teledyne API N500 CAPS NO Analyzer 08977D DCN88743...
