Online NDUV Gas Analyzer SA-200

S-ANALYZER 200 NDUV series use NDUV gas measurement technology, is a multi-gas analyzer for 19"rack-mounting with integrated NDUV Gas sensor, up to 5 components can be measured. S-ANALYZER 200 NDUV is equipped with a touchscreen. In combination with a well-arranged menu structure, intuitive and user-friendly operations is assured. All necessary status-, threshold-, and alarm messages for effective monitoring are provided as analogue and digital signals. Graphic display of measurement curves are also as option offered.

 

  • Type :

    SA-200 NDUV

The gas analysis based on the NDUV gas measurement technology is a well-known method to determine the concentration in complex gas mixtures. 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 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.
