The STIP-scan CAS74 sensor monitors the absorption coefficient, various carbon parameters and the nitrate concentration in wastewater applications. It features user-defined settling periods to minimize particle interferences, ensuring stable measured values at any time. By indicating load peaks, STIP-scan increases your plant safety. The low-maintenance sensor is self-cleaning and chemical-free, helping to reduce operational expenditure.


  • Measurement directly in the process

  • Safe, chemical-free measurement reduces operational expenditure

  • Spectral measurements from 200 to 680 nm for detailed information about the entire process

  • No external sampler or sample conditioning required

  • Self-cleaning and low-maintenance

  • Suitable for harsh process conditions

  • Optimum spectral adaption to specific measuring tasks (dyes, color measurement etc.)

Field of application

The STIP-scan CAS74 multiparameter sensor is used with the CAM74 transmitter in wastewater applications, such as:

  • Continuous monitoring of organic contamination

  • Continuous monitoring of nitrate

  • Measurement of sludge parameters

  • Special measurements in the spectral range from 200 to 680 nm (for dyes, color measurements, etc.)
