The new series offers the possibility of measuring two different sample streams. For example, two boilers can be examined at the same time with one analyzer, the model CLD 822 SS d, which offers two independent NOx measurements. The instrument can also be adapted to two different measuring ranges. The model 824 has two channels, one having a maximum range of 5'000 ppm and a resolution of 0.2 ppm, the other showing a maximum range of 500 ppm and a resolution of 0.02 ppm. This is well suited for cases where the gas has to be measured before and after the process.
