TEST METHODS SPECIFICATIONS
APPLICATION
Drinking water supplies and distribution systems, swimming pool and
spas, sewage and chlorinated waste waters, process waters and sanitizing
solutions.
RANGE
0 to 4.0 ppm Chlorine (may be extended by dilution)
0 to 7.0 ppm Bromine (may be extended by dilution)
METHOD
In the absence of Iodide, Free Available Chlorine reacts instantly with the
buered diethyl-p-phenylenediamine indicator (DPD) to produce a pink-red
color in proportion to the amount of chlorine present. Subsequent addition of
potassium iodide produces a rapid color response from the combined forms
of chlorine (chloramines). In buered samples, bromine reacts with disthyl-
p-phenylene diamine (DPD) to produce a pink-red color in proportion to the
concentration of bromine present.
HANDLING & PRESERVATION
Chlorine and bromine in aqueous solutions, particularly weak solutions, are
not stable. Exposure to sunlight or agitation will accelerate the reduction of
chlorine and bromine. For chlorine samples, ll sample containers to the top
and cap tightly. Analyze samples as soon as possible after collection. Samples
to be analyzed for bromine cannot be preserved or stored.
INTERFERENCES
The only interfering substance likely to be encountered is oxidized
manganese. The extent of this interference can be determined by treating a
sample with sodium arsenite to destroy the chlorine or bromine present, so
that the amount of interference can be estimated. Chlorine, bromine, and
iodine will give a positive result and should be considered an interference
unless the test is being performed specically for that parameter.
CALIBRATION
The colorimeter is precalibrated. In order to comply with NPDWR or NPDES
reporting regulations, the calibration should be checked periodically by using
a set of reference standards including a 0 mg/L blank and 0.3, 1.0, and 3.5
mg/L chlorine. To prepare these standards, a LaMotte 1000 mg/L standard
chlorine equivalent solution (Code 3858) is available. Consult with your local
regulatory agency to determine standardization frequency.

11. Subtract free chlorine reading from total chlorine reading to obtain
concentration of combined chlorine.
12. Press to turn o the colorimeter or press EXIT to exit to a
previous menu or make another menu selection.
Levels of chlorine about 4 mg/L will cause a bleaching eect on the DPD
indicator, and may give a false indication that no chlorine is present. If if is
possible that the chlorine concentration is greater than 4 mg/L, perform test
on a diluted sample and multiply the result by appropriate dilution factor.
CAUTION: DO NOT leave reacted samples in test tubes. Discard sample and
thoroughly rinse tubes. If allowed to remain, DPD wil stain tubes, signigicantly
impairing the operation of the colorimeter. If necessary, acid wash, and
vigorously clean glassware with test tube brush and detergent.
NOTE: For the most accurate results, samples over 4 ppm chlorine should be
diluted with chlorine demand free water and re-tested.
NOTE: The meter will remember the last scanned blank reading. It is not
necessary to scan a blank each time the test is performed. To use the
previous blank reading, instead of scanning a new one, scroll to Scan Sample
and proceed. For the most accurate results, the meter should be blanked
before each test and the same tube should be used for the blank and the
reacted sample.

CALIBRATION
CHLORINE STANDARDS
The meter should be calibrated with free chlorine standards. The calibration
should be done with a distilled or deionized water blank and one chlorine
standard of known concentration. The concentration of the calibration
standard should be similar to the expected concentration of the sample that
will be tested.
To perform a bromine calibration, prepare a bromine with a concentration
that is equivenlent to a chlorine dioxide standard that is within the range of
the chlorine dioxide test. (1 ppm chlorine = 1.9 ppm bromine). Follow the
procedure below but select the bromine test.
Chlorine Secondary Standards (Code 4140-03) are available to verify the
performance of the meter.

The meter may be interfaced with any Windows-based 64 bit computer
by using the LaMotte WaterLink Connect program and a USB cable. The
program will store test information and results in a local database, and allow
for exporting this data to a comma separated value (CSV) le. The meter

BATTERY
BATTERY/AC OPERATION
The colorimeter may be operated on battery power using a USB wall adapter
or USB computer connection. If using the meter as a bench top unit, use the
wall adapter if possible to extend the battery life. The meter will remain on
when the USB adapter is used.
To charge the battery with the wall adapter, plug the smaller end of the USB
cable (USB mini B connector) into the meter and the larger end of the USB
cable (USB type A connector) into the wall adapter. Plug the wall adapter into
an AC outlet. Reinsert the rubber USB port plug after charging. To charge the
battery from a computer, plug the smaller end of the USB cable (USB mini B
connector) into the meter and the larger end of the USB cable (USB Type A
connector) into a USB port on a computer. The battery icon will show no bars
and ash when the unit rst turns on. Then the indicator will indicate the
battery status by showing 0, 1, 2, 3, or 4 bars.
It will take 6 hours to fully charge a low battery. The battery icon will ash
when the battery is charging. The battery icon will show four bars and stop
ashing when it is fully charged. The charging circuit will automatically switch
to a oat charge when the battery is fully charged. The charger may remain
connected. Some computers will NOT supply power to their USB ports during
standby operation. The wall adapter will charge the unit continuously.
Storing the meter above ambient room temperature will decrease the battery
charge more quickly than storage at room temperature. If the meter does
not turn on, it means that the battery is at a very low charge. Charging the
battery with the wall adapter in this state may take up to 10 hours. At low
temperatures, approaching 0 °C, the battery will charge more slowly. It will not
charge at all below 0 °C. The battery icon will show no bars and continuously
ash if the battery is getting low but the unit will still operate normally. A
“Low Battery” message on the status bar of the display will replace the time
