The S-ULTRA.sens module uses modern optical components to achieve optimized analyzer results. We use a special LED/EDL-Technology in order to get stable radiation emission. The result is a high resolution gas analysis system which can detect gas concentration changes of less than 1ppm . 

The gas analysis based on the NDUV techniques is a well-known method to determine the concentration in complex gas mixtures. The S-ULTRA.sens module uses modern optical components to achieve optimized analyzer results. 

The entire structure can be disassembled to make the maintenance/service easier. The different devices are sealed with O-Ring joining. The stainless steel sample cell is coated with a protection layer. The length is 100mm. For the combined detection of NO, NO2 and SO2 three different light sources are integrated. 

For example, we use AlGaN-LED for the UV light source which can cover 360-230nm wave length. For enhance the life time of the light source, we use special control board, which can let the light source achieve more than 3 years life time, which solve the well-know problem of shortcoming of UV light source. 

S-ULTRA.sens is suitable for all kind of complex industry environment, special has good performance in low range CEMS measurement, which can good measure NO and NO2 without transition device.
