For Monitoring: NO / NOx / NO2

CLDdual

The CLDdual is a dual-channel detector for the precise detection of nitrogen oxides. The parallel reaction chambers enable the simultaneous measurement of NO and NOX. The CLDdual is heatable to 190 °C for raw gas measurement and ideally suited for high as well as low concentrations.
