Rigorous Accurate Testing

  • It is important to test water-using systems to ensure biological control.
  • Plate counts suffer from over 60% false negatives due to sample degradation during shipping. 
  • Plate counts can’t detect VBNC (Viable But Non Culture-able) forms of legionella which are still capable of causing illness and death.
  • Independent testing assures that your results are accurate and your system stays clean and free of disease.
