DPD 1 Chlorine testing tablets

  • 50 tablets in total
  • DPD is an abbreviation of diethyl-p-phenylene diamine. DPD tablets react with pool water containing chlorine or bromine, colouring the water sample various shades of red. The deeper the colour, the higher the concentration of sanitiser.
  • DPD tablet tests have largely replaced orthotolidine testing 
  • The DPD tablet No.1 is used to measure free or "available" sanitiser, the useful hypochlorous or hypobromous acid required for sanitising.
  • DPD tablet No.3 is used after DPD1 to measure total chlorine or bromine. The difference between the two measurements is the combined chlorine (chloramine) or bromine (bromamine) value.
  • Chloramines are an undesirable form of chlorine that do not sanitise and cause irritation. Bromamines have some sanitising value but do not generally irritate like chloramines. Either though indicates bather pollution.
