rinse cell thoroughly and fill
with water then add two (2)
drops of bleach (5-8%) and
clean with brush until stain
is removed. Caution: Avoid
contact of bleach with eyes
and clothing. TIP
For water temperatures above 95°F/35°C (hot tubs), press READ

and a fresh strip. This result is automatically stored in
the CL(3) menu. After testing is complete, rinse the
sample cell immediately and clean with brush.
TOTAL BROMINE: If CL result is <4ppm multiply by 2.2 (ex. 3ppm in CL
menu is 6.6 Total Bromine). If result is 4ppm or higher multiply by 2.0.
Important! Do not empty the CELL if you are also testing for
Combined Chlorine. You will need the sample.

Substance
Interfering Levels & Treatments
Acidity If sample has acidity above 150mg/L CaCO3 test may not develop
full color. Neutralize to pH 6.0 to 7.0 with 0.5N Sodium hydroxide.
Alkalinity If sample has alkalinity above 200mg/L CaCO3 test may not
develop full color. Neutralize to pH 6.0 to 7.0 with 0.5N Sulfuric
acid.
Bromine & Bromamines,

Chlorine, Cl2 Color similar to other oxidizer reaction at all levels.
Chlorine Dioxide, ClO
2
Color similar to other oxidizer reaction at all levels.
Copper, Cu+2 Color development is reduced above 10 ppm (mg/L).
Iodine, I2
Color similar to other oxidizer reaction at all levels.
Manganese, Oxidized

Oxidized (Cr+6)
See AWWA procedure 4500-CL F, 1(d) for removal of
interferences.
Monochloramines (NH

Cl)
(applies to DPD-1 only)
Monochloramine interferences are known to occur in free chlorine
DPD methods. This interference is dependent on temperature and
monochloramine concentration.
Ozone, O3
Color similar to other oxidizer reaction at all levels.
Peroxides Interference is possible.
pH Typical pH samples of potable water with a pH of 6.0 to 9.0 are
OK. If outside this range adjust to pH 6.0 to 7.0 using acid (0.5N
Sulfuric acid) or base (0.5N Sodium hydroxide).

CAP CELL AND READ RESULTS
Place the Cell Cover onto the CELL and READ
result displayed as Combined Chlorine. This result is

DPD will stain the CELL wall if allowed to remain in the CELL. To remove staining, rinse
cell thoroughly and fill with water then add two (2) drops of bleach (5-8%) and clean with
brush until stain is removed. Caution: Avoid contact of bleach with eyes and clothing.
To get final result as Total Chlorine, press READ again.
Note: If second DPD-1 strip was used for Free
Chlorine >6ppm then Total Chlorine will have to
be manually calculated.
