Test 1 Chlorine-Free/5 or Chlorine-Free/10
Standard Range: 0-5.00mg/l (ppm) Cl
Extended Range: 0-10.0mg/l (ppm) Cl
Colour change: Colourless - Purple/Red
1 Rinse test cuvette with sample leaving
two or three drops in the tube.
2 Add one DPD 1 or DPD XF tablet, crush
tablet and then fill the test tube with
sample to the 10ml mark. Mix to dissolve
tablet fully and ensure no particles remain.
3 Take photometer reading immediately.
The result may drift on standing.
4 Retain test solution if the Total
Chlorine Follow-On Test is required.
Test 2 Chlorine-Total/5 or Chlorine-Total/10
Standard Range: 0-5.00mg/l (ppm) Cl
Extended Range: 0-10.0mg/l (ppm) Cl
Colour change: Purple/Red from Test 1
increases in intensity
Carry out this test on the solution
remaining from the Free-Chlorine/5 test.
1 If any shock treatment chemicals have
been added to the pool, add one DPD
Oxystop tablet, crush and mix to dissolve.
Stand for one minute before proceeding.
This will prevent a false response caused
by the shock treatment chemicals.
2 Add one DPD 3 or DPD XT
tablet, crush and mix to dissolve.
3 Stand for two minutes
to allow full colour development.
4 Take photometer reading
after two minutes have elapsed.
Note: To obtain Combined Chlorine
residual subtract Free Chlorine result
from Total Chlorine result:
Combined Chlorine =
Total Chlorine - Free Chlorine
