Hach Pacific now stocks Freechlor F pocket colorimeters, supplied in a complete kit and suitable for the determination of free chlorine in the presence of manganese and chloramines.

Problems with interfering substances can occur when measuring free chlorine via DPD substances. The interference of manganese is instantaneous and not distinguishable from free chlorine unless the analyst knows the amount and compensates for it.

Chloramine interference is dependant on the type, level and temperature, and their presence is only noted as a slow, steadily increasing free chlorine value.

Key features of these pocket colorimeters include:

  • single or multi parameter versions
  • simple operation
  • waterproof, rugged and light weight
  • large display
  • up to 99 different parameter measurements available, eg chlorine, manganese, iron, aluminium, fluoride, and monochloramine.
