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
buffered diethyl-p-phenylenediamine indicator (DPD) to produce a 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 buffered 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, fill 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. Iodine, bromine and
chlorine can also interfere, but these are not normally present unless they
have been added as additional sanitizers.
CALIBRATION
The single test 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.

NOTE: For the most accurate results, samples over 7 ppm bromine 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 chlorine standard with a
concentration that is equivenlent to a bromine standard that is within the
range of the bromine test. (1 ppm chlorine = 2.25 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.

SETTING THE BACKLIGHT TIME
The backlight illuminates the display for enhanced viewing. If Button Control
is chosen the backlight button on the key pad will act as an on/off switch and
the backlight will remain on or off when the meter is being used. When one
of the other settings — 10, 20 or 30 seconds — is chosen, the display will be
illuminated for the specified amount of time after any button is pressed. As a
precaution, the backlight will not illuminate during turbidity measurements to
avoid interference from stray light.
NOTE: The backlight feature uses a significant amount of power. The longer
the backlight is on, the more frequently the battery will have to be charged if
the USB/Wall Charger is not being used.
