- Model Serinus 60 - Direct Nitrogen Dioxide Analyser


Ecotech presents the latest addition to the Serinus range: The Serinus 60 NO₂ analyser with Cavity Attenuated Phase Shift (CAPS) spectroscopy technology. This technology allows direct measurement of nitrogen dioxide (NO2), rather than an indirect calculation from a chemiluminescence analyser. Using a modulated blue LED light source, the detector measures the phase shift attributable to the level of NO2 in the measurement cell over an average path length of several kilometres.

No converter, no high vacuum, no ozone and no chemical reactions are required.

Never has accurate measurement of NO2 been more important, or higher on the agenda, for environmental protection. Studies and health reports have raised awareness of the risks to human health from nitrogen dioxide, such as decreased lung function and other respiratory conditions.

The solution starts with fast, accurate data, and nothing beats measuring directly. That’s why we have launched the Serinus 60; an affordable NO2 analyser that gives accurate and timely results.

Nitrogen dioxide is in the forefront of concerns over air pollution in cities worldwide. Authorities have been forced to take drastic measures, such as odd-even number plate days, green taxes, car-scrapping and ride-sharing programmes in an attempt to mitigate the problem. But, as urban populations, industry, vehicle ownership and transportation increase, the underlying issue is getting worse.

For environmental protection agencies NO₂ has long been ‘on the radar’ as a criteria gas. Until the advent of the advanced and more affordable CAPS technology, levels were derived from indirect measurement, posing disadvantages such as precision of measurement and response when levels were dynamic.

The Serinus 60 now makes direct, responsive and accurate measurements of this key criteria gas possible.

Importantly, it also delivers these advantages in a highly affordable package.

Serinus 60. It’s a game changer.
For years now, the Serinus range has been recognised internationally for precision and usability. The new Serinus 60 is no different. It has been designed from the outset with the user in mind: intuitive to use, simple to configure and offering in-the-field accuracy and reliability.

These qualities count, when the risks from NO2 are under scrutiny like never before.

By delivering direct measurement, in an affordable and usable package, Serinus 60 is a huge step forward in addressing NO2 pollution in an increasingly urbanised world.
