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.
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.
