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.
- Measures NO2 directly – highly selective and no cycle time (switching between NOx and NO)
- Accurate, repeatable and rapid readings every five seconds
- Less maintenance than chemiluminescence analysers
- Low power consumption
- No converter or ozone generator
