Benefits

  • Wide measuring range: From trace measurement up to chlorine dioxide concentrations of 200 mg/l.
  • Easy installation: sensor can be installed in the modular Flowfit CYA27 assembly or in immersion assemblies and faster poloarization time with the new Memosens 2.0 technology.
  • Fast response time provides accurate process view and enables prompt reaction to process changes as well as efficient process control.
  • Increased process safety: precise and long-term stable measurement ensures consistent process monitoring and allows for lowest disinfectant concentration.
  • More process up-time thanks to fast sensor exchange: precalibrate the sensor in your lab and then swap it into your process with plug & play.
  • Easy combination with other relevant parameters of liquid analysis thanks to connection to the Liquiline multiparameter transmitter.

  • Cooling systems or towers: to avoid pathogen growth
  • Process water: for hygienic and safe packaging and bottling of products in food processing
  • Beverage and reverse osmosis plants: to secure the absence of chlorine dioxide
  • Drinking water: to ensure sufficient disinfection
Benefits
  • Wide measuring range: From trace measurement up to chlorine dioxide concentrations of 200 mg/l.
  • Easy installation: sensor can be installed in the modular Flowfit CYA27 assembly or in immersion assemblies and faster poloarization time with the new Memosens 2.0 technology.
  • Fast response time provides accurate process view and enables prompt reaction to process changes as well as efficient process control.
  • Increased process safety: precise and long-term stable measurement ensures consistent process monitoring and allows for lowest disinfectant concentration.
