UP-CLD NO/NO x

Continuous Emission Monitoring (CEMS) made easy

UP-CLD is a ultra portable Chemiluminescence NO(x)/NO analyzer in a package that is compact, crushproof and travels anywhere. The analyzer unit can be used as a standalone monitor for research purposes etc. or for continuous emission monitoring as a part of the UP-CEMS concept. 

Its operation is based on the chemiluminescence of an activated molecular NO2 species (NO2*) produced by the reaction between NO and O3 in an evacuated chamber. The NO molecules react with ozone to form the activated NO2* species according to the reaction shown below:

NO + O3 → NO2* + O2

Pressure and temperature compensation minimizes effects caused by changes of conditions. The sensor continuously self-checks on key parameters and a warning is given immediately on finding an out-of tolerance parameter.

Features and benefits

  • The UP-CLD analyzer is designed to be ultra-portable, making it easy to transport and set up for on-site measurements anywhere, whether for research purposes or continuous emission monitoring

  • Its compact and rugged design ensures durability and protection during transportation and use in various field environments

  • The analyzer unit can function both as a standalone monitor for research applications and as part of the UP-CEMS (Continuous Emission Monitoring System) concept for continuous emission monitoring in industrial settings

  • CEMS in combination with the OXYDAN® exhaust gas sampling probe

  • 12V DC Supply
