CLD Analyzer
For monitoring: NO, NO2, NOx
CLD based Analyzers | NO, NO2, NOx Analyzers
The TRACE-GAS CLD analyzers are based on the chemiluminescence effect for the detection of nitrogen oxides. They combine a direct measuring method with fast reaction times and a long lifetime. They convince by low maintenance requirements and extremely stable measured values.
Examples of customer-specific projects using CLD technology
Here you can have a look at our previously developed analyzers in the CLD technology area. Please do not hesitate to contact us, even if your application is not listed. We develop individually based on your requirements!
For monitoring: NO, NO2, NOx
CLDmono Analyzer
Single channel CLD analyzer for precise detection of nitrogen monoxide (NO). By using a NOX-converter and a switch at the reaction chamber, nitrogen monoxide and higher value nitrogen oxides (NOX) can be measured sequentially. In addition, the instrument with converter can also be used for pure nitrogen oxide (NOX) measurement.
For monitoring: NO, NO2, NOx
CLDdual Analyzer
The dual-channel analyzer with its parallel arranged reaction chambers allows the simultaneous measurement of NO and NOX.
For raw gas measurements the CLDdual can be heated to 190°C and is ideally suited for both high and low concentrations.
The NO2 content can be determined by calculation.
By integration of a NDIR sensor an additional measurement of CO/CO2 is possible.
