Flourometer measures the concentration of a fluorescent substance in a liquid sample [PTSA (0-300 ppb)]. These meters have a built-in sample cell and samples can be directly filled into the cell.


Dual-channel flourometer measures PTSA (0-300 ppb) and Conductivity (0-15000µS/cm)

• Cooling tower fluorescence tracing
• Environmental monitoring


  • Extra color and turbidity parameters measured are used for automatic compensation to eliminate interference.
  • No sample cuvette is needed and variations associated with the cuvette is eliminated.
  • Large color graphic screen that can be read in direct sunlight
