FOR BEST ACCURACY
The Chlorine eXact
®
EZ photometer has a 5 minute auto-shutoff 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 finally -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.
Always fill the cell to capacity (4mL); be careful not to splash liquid over
the side.
Test immediately after filling 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 find 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.

CHLORINE EXACT®EZ ACCURACY
All tests have been calibrated using certified reference standards
and analytical spectrophotometric methods. The Chlorine eXact
®
EZ has been factory calibrated and will stay valid because of its
exceptional quality. We are so confident in the Chlorine eXact
®
EZ, we offer an industry leading 2-year warranty.
We built the Chlorine eXact
®
EZ to be easy, accurate and
environmentally friendly. We have achieved this by utilizing our
patented eXact
®
Strip Micro Technology, which uses 60% less
water and chemistry than alternative methods. Instead of using
a 10mL water sample, eXact
®
Strip Micro uses a 4mL water
sample. The accuracy of the meter is maintained by designing
the sample cell with an 11mm path-length.

16
©2017, Industrial Test Systems, Inc. Printed in USA
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.
Our studies have shown that scratches on the cell will not
compromise the accuracy of your results because of the
cell’s fixed position.
WARRANTY (2 YEARS)
Registration of your eXact
®
photometer must be received within 30 days from
date of purchase to activate the warranty. Registration is available over the
phone [phone] Ext. 0) or online at sensafe.com/micro/warranty/
(Personal data is kept confidential). The eXact
®
photometer is warranted to
be free from defects in materials and workmanship for a period of two (2)
years from the date of purchase by the customer. ITS will repair or replace,
at its discretion, product which is deemed to be faulty due to manufacturing
defect. Warranty does not cover product damage caused by abuse (such as
crushing a tablet in the cell), battery corrosion damage, or improper use. If
the meter is faulty or otherwise defective contact ITS by phone [phone]-
9712 Ext. 0) or email ([e-mail]) to describe the problem and obtain
a return authorization form before returning the photometer to ITS. Damage
caused by improper packing of the photometer for return shipment to ITS
will not be covered by the warranty. Customer is responsible for shipping
charges to ITS. ITS pays postage when photometer is returned to customer. A
maximum processing fee of $75 will be charged for repair or replacement of
non-registered photometers and damages not covered by this warranty. The
repair or replacement of the photometer will not extend or renew the period of
guarantee. This warranty does not affect your statutory rights. The warranty is
not transferable.

COMPLIANCE TESTING
This DPD test system for Chlorine and
Chlorine Dioxide are accepted for reporting
by most health departments because the
tests are USEPA (DIN Standard 38 408 G4/G5, ISO 7393/2)
accepted for testing requirements for Free Chlorine, Total
Chlorine, and Chlorine Dioxide.
The compliance requirement is a photometer wavelength to
measure between 490 and 530nm. The Chlorine eXact
®
EZ smart
photometer uses a 525nm wavelength and 11 mm path-length.
The eXact
®
Strip Micro CL/Cd (DPD-1) use the same reagents
and proportions, and the resulting solution pH is maintained
between 6.2 and 6.5 as specified by AWWA method 4500-Cl
G/ClO2-D. 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, the eXact
®
Strip Micro CL (DPD-4) for Total Chlorine,
and the eXact
®
Strip Micro Cd (DPD-1) for Chlorine Dioxide meet
your reportable testing requirements because the eXact
®
Strip
Micro strips deliver the same chemicals in identical proportions.
Consult with your local health department for official regulations.
