TELEDYNE API Model N500 CAPS NOx (TAPI)

TELEDYNE API Model N500 CAPS NOx (TAPI)

The Teledyne API Model N500 CAPS NOx analyser is a Cavity Attenuated Phase Shift (CAPS), non-chemiluminescent NOx analyser. Using CAPS Spectroscopy to measure ‘true’ NO₂, NOx and NO gases, the Teledyne API Model N500 provides an improved option for NO₂, NOx and NO measurement accuracy and reduces instrument operation and maintenance costs. CAPS technology is inherently accurate and sensitive, requires less maintenance than chemiluminescence and uses less power. Teledyne-API’s first direct true NO₂ analyser, the T500U has been a popular instrument with scientists and air quality specialists looking for a faster and more precise measurement of NO₂ that cannot be offered by chemiluminescence. The Model N500 like the T500U, uses CAPS technology for true NO₂ measurement but it adds the ability to measure the NO component of NOx. The instrument combines direct NO₂ measurements with highly efficient gas phase titration (GPT) to convert and measure the NO gas component. The new Model N500 CAPS NOx / NO₂ / NO analyser is available exclusively in Australia and New Zealand through Thomson Environmental Systems.
