INTRODUCTION
Chlorine is added to water to kill bacteria and other disease-producing organisms,
control algae, and remove undesirable odors and colors. Chlorine added to water quickly
forms hypochlorous acid, HClO, also known as Free Available Chlorine, the active
ingredient responsible for chlorine’s sanitizing capabilities. Free Available Chlorine
combines with impurities in the water to form chloramines and other organic nitrogen
compounds. In combined form, its sanitizing capability diminishes, and higher levels of
chlorine are necessary to achieve effective sanitation. Therefore, it is essential to
chlorinate to the point of establishing a Free Available Chlorine Residual, and then to
maintain that residual at a recommended level.
NOTES: If either chlorine reading displays , repeat procedure on diluted sample,
and multiply the result by the appropriate dilution factor. See 1200 Colorimeter
Instruction Manual for procedure.
Levels of chlorine above 10 mg/L will cause a bleaching effect on the DPD indicator, and
may give a false indication that no chlorine is present. If it is possible that the chlorine
concentration is greater than 10 mg/L (e.g. after shock treatment), perform test on a
diluted sample and multiply the result by appropriate dilution factor.
CHLORINE TEST PROCEDURE - DPD METHOD
Fill the Water
Sample Bottle
(28021) with
sample water. This
will be used to
dispense sample
water for the tests.
Push the READ
button to turn the
