Enviro Technology introduces ground-breaking NOx analyser

Duncan Mounsor Director

ET is delighted to announce the launch of a revolutionary new non-chemiluminescent NOx analyser from analyser giant Teledyne-API.

The new Model N500 CAPS NOx analyser uses superior Cavity Attenuated Phase Shift (CAPS) Spectroscopy to measure ‘true’ NO2, NOx, and NO gases. 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.

Teledyne-API’s first direct true NO2 analyser, the T500U has been a popular instrument for ET, particularly favoured by scientists and air quality specialists looking for a faster and more precise measurement of NO2 that cannot be offered by chemiluminescence. The new Model N500, like the T500U, uses CAPS technology for true NO2 measurement but now adds on to this by measuring the NO component of NOx. This really is a revolutionary instrument, and we are very excited to be able to start offering it to our clients.

Duncan Mounsor Managing Director

Like all Teledyne-API gas analysers, the new Model N500 CAPS NOx / NO2 / NO analyser is available exclusively in the UK and Ireland through Enviro Technology Services Ltd.
