About Your eXact
®
Micro 20 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®Micro 20 meter is controlled by four buttons:
1. MENU: With each press, the MENU button advances through the tests available in the current Select
Group. 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 2ndODWHVWUHVXOWHWFDQG¿QDOO\ZKLFKLVWKHROGHVWUHVXOWUHWDLQHG2QO\WKH
last 20 readings are stored in each menu.
2. 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.
3. SELECT: With each press, the SELECT button advances through the Select Group 1 through 7. The
current Select Group will appear as a small digit to the right of the selected MENU (example:
CL11
).
4. ON/ZERO:KHQ¿UVWSUHVVHGWKLVEXWWRQWXUQVWKHPHWHURQ:KHQWKHPHWHULVRQDQGWKLVEXWWRQLV
pressed, it zeroes the sample in the cell. It is recommended that each new water sample analyzed is zeroed
before testing, to maximize sensitivity and accuracy.

Compliance VHULÀFDWLRQIRU)UHHDQG7RWDO&KORULQH7HVWLQJ
This DPD test system is accepted by most health departments because this test is USEPA (DIN
6WDQGDUG*,62accepted for testing requirements for Free and Total Chlorine. The
Micro 20 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 reagents
and proportions, and the resulting solution pH is maintained between 6.2 and 6.5 as VSHFL¿HGby
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.
eXact
®
Strip Micro has been designed to offer the user a more “Green” and cost-effective alternative to testing.
Instead of using a 10mL water sample, eXact
®
Strip Micro uses a 4mL water sample, which uses up to 60% less
chemical per test. The accuracy of the meter is maintained by designing the photo cell with a 20mm pathlength.

Color development is reduced above 10 ppm (mg/L).
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).

This procedure is only valid when run as a continuation of the eXact®Strip Micro CL
(DPD-1 Free Chlorine ) Test Procedure located on the previous page.
REMOVE STRIP
Remove one (1) eXact

Strip Micro CL (DPD-3) Part No. 486638, from the bottle before
beginning the test. Set the strip in a dry, convenient place and recap the bottle immediately.
DIP STRIP AND PRESS “READ”
Dip the eXact® Strip Micro CL (DPD-3) into the CELL and immediately press READ. This
starts the 20 SECOND countdown timer. During this time move the strip in a gentle back
and forth motion
(approx. two strokes/ Sec)
. Remove and discard the strip when “1” on the
display disappears.* The cursor will move across the display while the meter prepares to
measure the sample.
Record the value displayed and this value is automatically stored in the
CL MENU.
(NOTE: The Iodide added with DPD-3 will, in the presence of Combined Chlorine or
Chloramines, convert into Iodine).
PRESS READ AGAIN
Press READ again and the meter will count down and display the next reading. If this
reading matches the previous result, then record this as the Total Chlorine result.
This value
is automatically stored in the CL MENU.
After testing is completed, rinse CELL immediately.
Record the highest value the meter displayed as your Total Chlorine result.
*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.
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 color).
*NOTE: When testing outdoors (sunlight), for best accuracy, use the Mixing Cap/Cell Cover when Zeroing and Reading the sample.

The eXact®Micro 20 Meter is not compatible for use with DPD-1, DPD-3, and DPD-4 powder
pillows, tablets, and liquids available from other manufacturers. Accurate results can only be
guaranteed by using genuine eXact®Micro strips or reagents (reorder information on page 19).
Our lab testing with the Micro 20 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).
