AccurAcy & cAlibrAtion
All tests have been calibrated using certied reference standards and
standard analytical spectrophotometric methods. The algorithms in
the software reect the best correlation of the Pool eXact
®
EZ system
against the AWWA, US EPA , DIN, and ISO reference test methods
for chlorine. Studies show that the Pool eXact
®
EZ System repeatedly
agrees with an EPA Compliant reference method greater than 99%. The
Pool eXact
®
EZ meter Advanced Photometric System has been factory
calibrated and you can expect the xed calibrations in the meter to be
valid for the life of the meter because of the quality, Long-Life LED, the
photo cell, and the software.
Free & totAl chlorine testing heAlth DepArtment compliAnce
This DPD test system for Chlorine is accepted for reporting by most
health departments because the test is USEPA (DIN Standard 38 408
G4, ISO 7393/2) accepted for testing requirements for Free and Total
Chlorine. The compliance requirement is a photometer wavelength to
measure between 490 and 530nm. The Pool eXact®EZ photometer uses
a 525nm wavelength. 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 specied by AWWA method 4500-Cl G. The
USEPA does not “approve” commercial DPD delivery systems. The
eXact®Strip Micro CL (DPD-1) for Free Chlorine, and the eXact®Strip
Micro CL (DPD-3) for Combined Chlorine 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.
About the built-in sAmple cell
The built-in sample cell is made of transparent plastic; the sturdy cell design
will last for over 20,000 readings. Scratches on the cell will not compromise
the accuracy of your results because of the cell’s xed position.
cleAning the sAmple cell
Fill the sample cell with water and use the enclosed cleaning brush
to scrub the sample cell thoroughly. Rinse the cell. You can use dish
soap or distilled white vinegar for cleaning the cell if needed. NEVER
use solvents such as acetone.

• The Pool eXact®EZ photometer has a 5 minute automatic shutdown timer.
• Each test menu can store 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 2nd latest result, etc; and nally -01, which is the oldest result retained.
Only the last 20 readings are stored in each menu. This meter is able to store 100
results in memory (20 in each menu).
• Before testing, rinse the meter sample cell with the sample water 3 times.
• Pool water samples should be taken 18 inches below the surface. Submerge the meter
with open cell facing down 18 inches then turn meter upright at that depth to ll the cell.
Remove meter from water with the sample for testing.
• Always ll the cell to capacity (4ml); be careful not to splash liquid over the side.
• Test immediately after lling the cell with the water sample.
• To obtain optimal accuracy when testing outdoors (sunlight), use the cell cover when
zeroing and reading the sample.
• Due to the strip slitting process, you may nd one or two strips that are noticeably
smaller or larger in width than the normal strips in the bottle. These should be
discarded. Using these strips may give unreliable results.
• Meter is not compatible for use with powder pillows, tablets, or liquids from other
manufacturers.
• Dip strip for entire countdown.
• Each eXact®Strip Micro is valid for ONLY one test. Discard strip after use.
• Dry the outside of the meter before storage.
• Remove batteries before storing for prolonged periods.
• Store the meter and test materials out of direct sunlight and away from chemical
storage areas.
• Minimize exposure of meter and test reagents to heat above 90°F (32°C).
• When installing batteries, verify the O-ring is still attached to the screw before
tightening.
• Cleaning the cell with water and brush after each test is recommended for best
accuracy and prior to storage of unit.
