LAR Nitritox / ToxAlarm- Toxicity

LAR’s toxicity analyzer NitriTox continually monitors water treatment plants for pollutants / ToxAlarm continually monitors drinking and surface water for pollutants. Potential toxins in water are determined through the reaction of highly sensitive bacteria. The measurements follow at intervals of less than 5 minutes. Thus allowing enough time to introduce countermeasures after the occurance of pollution. What’s more, the NitriTox offers three warning levels, which can be individually set.


  • Measurement range: 0 – 100% Toxicity
  • Response time: 5 – 10 minutes (depending on application)
  • Toxicity monitoring
  • Self-regenerating culture of nitrifying bacteria
  • Highly sensitive
  • No memory effects
  • Low operational cost
  • High reproducibility
  • No purchase of test organisms required
  • According to DIN EN ISO 9509:2006


  • Water influent
  • Industrial waste water
  • Surface Water Monitoring
  • Drinking Water Protection
  • Ground Water Protection
