About Your eXact
®
Chlorine Plus Instrument
In order to save power, the meter is designed to turn off after 3 minutes (timed from the last button pressed).
Should the meter turn off in the middle of a test, the last stored zero in the meter will remain valid when the
meter is turned on again. Also, the test result is stored in memory for easy retrieval.
The eXact
®
Chlorine Plus meter is controlled by three buttons:
1. ZERO/ON:KHQ¿UVWSUHVVHGWKLVEXWWRQWXUQVWKHPHWHURQ:KHQWKHPHWHULVRQDQGWKLVEXWWRQLV
pressed, it zeroes the sample in the cell. Once the meter is zeroed, this zero value applies to all parameters
and is stored and retained even when meter turns off. However, it is recommended that each new water
sample analyzed is zeroed before testing, to maximize sensitivity and accuracy.
2. MENU: With each press, the MENU button advances through the tests in the following sequence: CL1,
bR2, O3, Cd4, PA5, HP6, PH7, HR8. Each test menu can store up to 20 results. To retrieve the stored
results, go to the desired test using the MENU key. When the desired test is displayed, press and hold
down the MENU key. Continue holding down the MENU key to scroll the stored results for that test, starting
with the most recent result. The meter will display, from memory, the last 20 readings in sequence beginning
with -20, which is the latest result, followed by -19, which is the 2
nd
ODWHVWUHVXOWHWFDQG¿QDOO\ZKLFKLV
the oldest result retained. Only the last 20 readings are stored in each menu. This meter is able to store 160
results in memory (20 in each menu).
3. READ: When pressed once, this button starts the timer for the parameter being tested. When pressed a
second time the meter exits the timer and immediately prepares to colorimetrically measure the sample, and
simultaneously stores the measurement in memory.
If the parameter being measured is below or above the detection range, the display will show “LO” (Under
Range) or “HI´2YHU5DQJHUHVSHFWLYHO\7KLVIHDWXUHLVPHQXVSHFL¿FDQGGRHVQRWDSSO\WRDOOSDUDPHWHUV

This DPD test system is accepted by most health departments because this test is USEPA (DIN
Standard 38 408 G4, ISO 7393/2) accepted for testing requirements for Free and Total Chlorine. The
Chlorine Plus meter uses a wavelength of 525nm; and the compliance requirement is that the
colorimeter wavelength is between 490 and 530nm. The eXact
®
Strip Micro CL (DPD-1) uses the same

by AWWA (American Water Works Association) method 4500-Cl G. It should be understood that the
USEPA does not "approve" commercial DPD delivery systems such as reagent powder pillows, tablets,
dispensers, or eXact
®
Strip DPD delivery devices. The eXact
®
Strip Micro CL (DPD-1) for Free
Chlorine, and the eXact
®
Strip Micro CL (DPD-3) or the eXact
®
Strip Micro CL (DPD-4) for Total
Chlorine meet your reportable testing requirements because the eXact
®
Strip Micro CL delivers the
same chemicals in identical proportions (see table below); therefore, the system is compliant. Likewise,
AWWA proportions are followed as required for Total Chlorine measurements using Potassium Iodide.

DPD-1 Free Chlorine Test Procedure
NOTE: N,N-diethyl-p-phenylenediamine (DPD) also reacts to form a magenta color with Ozone, Total Chlorine,
Permanganate, Iodine, and other oxidizers.
DO NOT discard the sample from the Free Chlorine test if you are planning to run eXact

Otherwise, rinse the cell immediately.

Color similar to free chlorine reaction at all levels.
See AWWA procedure 4500-CL F, 1(d) for removal of interferences.
Monochloramine interferences are known to occur in free chlorine
DPD methods. This interference is dependent on temperature and
monochloramine concentration.
Color similar to free chlorine reaction at all levels.
Interference is possible.
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).
CL1: Chlorine and Iodine react with N,N-diethyl-p-phenylenediamine as it is released from the strip to
form a magenta color, directly proportional to the Chlorine concentration. (Ozone, Bromine, and
Permanganate also form the same color)

Total Chlorine as the highest value the meter displayed.
*NOTE: Standard Method (4500-Cl G, procedure for total chlorine) requires the reading to
be made after 2 minutes from the time the KI is added. For compliance testing, you must
time the two minutes and then make your measurement. NOTE: From testing in our lab,
water samples above 70°F (20°C), generally, reach a stabilized reading quicker then 2 minutes.

Become familiar with the meter and the different tests by reading the instructions carefully.
The Free Chlorine, Combined Chlorine, and Total Chlorine reagents are compliant for meeting
USEPA (4500-Cl G); ISO 7393/2; and German DIN 38408 G4-2 requirements.
Observe the dip time (as required for the test) for accurate results.

Be sure the CELL LV¿OOHGWRFDSDFLW\PO
Rinse the CELL with clean water immediately after completing the test. (DPD will stain the CELL
wall if allowed to remain in the CELL)
Just before testing, rinse the sample CELL with the sample water several times to get a
representative sample. (Use deionized or distilled water for rinsing if you have a limited amount of
sample).
Store the meter and all test materials out of direct sunlight and away from chemical storage areas.
Minimize exposure of meter and test reagents to heat above 32°C (90°F).
Dry the outside of the meter when testing is complete or before storage of the meter.
When running a DPD-1 Free Chlorine test AFTER a Total Chlorine DPD-3, a Total Chlorine DPD-4,
or a HR Free Chlorine test, rinsing is very important to remove residual KI, which may interfere.
Each eXact
®
Strip Micro is valid for ONLY one test. Discard strip after single use in regular refuse
that is inaccessible to children and pets.
Each bottle of eXact
®
Strip Micro contains, at minimum, the quantity of strips notated on the bottle.

larger in width than the normal strips in the bottle. These should be discarded. Using these strips
may give incorrect results.
The eXact
®
Chlorine Plus Meter is not compatible for use with DPD-1, DPD-3, and DPD-4 powder
pillows, tablets, or liquids available from other manufacturers. Accurate results can only be
guaranteed by using genuine eXact
®
Micro strips or reagents (reorder information below).
Our lab testing with the Chlorine Plus meter has shown that zeroing and measuring of the sample
normally does not require any cell cover for accurate results, except in sunlight. To obtain optimal
accuracy when testing with the meter outdoors (sunlight), use the Mixing Cap/Cell Cover when
zeroing and reading the sample.
Remove batteries when meter is not used for more than a month (Warranty Requirement).

1. Unscrew the O-ring sealed battery cover counter-clockwise. Use proper sized pliers if necessary.
Do not disturb the sealing O-ring. Batteries are not included.
2. Remove the used batteries and install 4 new AAA batteries following the diagram for
correct polarity (see diagram). We recommend high qualityAAA alkaline batteries be used.
4. Replace the battery cover. Be sure to tighten the cover securely. Do not over tighten. This is
necessary for meter to be waterproof.
5. Dispose of the used batteries in accordance with your
local regulations.
