Teledyne-API Model N500 CAPS True NO2, NOx and NO analyser

The Model N500 CAPS NOX analyzer uses superior Cavity Attenuated Phase Shift (CAPS) Spectroscopy to measure True NO2, NOX, and NO gases. The instrument combines direct NO2 measurements with highly efficient gas phase titration (GPT) to convert and measure the NO gas component. An automatic baseline reference cycle accounts and compensates for any potential baseline drift due to varying environmental conditions.

CAPS technology is inherently accurate and sensitive, uses very little power, and requires far less maintenance than Chemiluminescence. The Model N500 raises the bar for NO2, NOX, and NO measurement accuracy, while simultaneously reducing instrument operation and maintenance costs.

Key features of the N500 unit include:

  • Ranges: 0-5 ppb to 0-1 ppm, user-selectable

  • True NO2 – NOx – NO measurements

  • Gas Phase Titration (GPT) for NO conversion and measurement

  • Large, vivid, and durable color graphics display with touch screen interface

  • Ethernet TCP/IP, RS-232/485 serial

  • Front panel USB connections for peripheral devices and firmware upgrades

  • Analog output and Digital I/O expansion (options)

  • Fast response compared to Chemiluminescence

  • Exceptional measurement sensitivity

  • Low power consumption

  • Extended maintenance interval

  • Adaptive signal filtering optimizes response time

  • Temperature & Pressure compensation

  • NumaViewTM and NumaViewTM Remote Operating Software

  • Two-year warranty​
