DPD No. 4

For the determination of total chlorine or ozone

  • Green Chemistry without boric acid
  • Highest accuracy of test results
  • Easy handling & application
  • Exact dosing & enormous shelf life
DPD No.4 is used as an indicator for pool hygiene. As part of the DPD method, it is used to determine the total chlorine content. The tablet is dissolved in the water sample. The measurement is then taken immediately. DPD No.4 can also be used for the determination of ozone.
