About Your eXact® Micro 8 Instrument
About The Accuracy/Calibration Of The Micro 8 Photometer System
The eXact® Micro 8 Advanced Photometric System has been factory calibrated for your convenience.
Customer calibration for your own special application can be performed in the Transmission Menu. You
can expect the fixed calibrations or algorithms 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 as written into the meter. A blue dye
calibration solution is available for verification of meter performance.
To save power, the meter is designed to turn off after 3 minutes (timed from the last button pressed).
Should the meter turn off, the last stored zero in the meter will remain valid when the meter is turned on
again. The eXact® Micro 8 Photometer is controlled by three buttons:
1. ZERO/ON: When first pressed, this button turns the meter on. When the meter is on and this button is
pressed, it zeroes the sample in the cell. Once the meter is zeroed, this zero value applies to all menu
parameters and is stored and retained even when meter turns off. It is recommended that each new water
sample analyzed is zeroed before testing, to maximize accuracy.
2. MENU: With each press, when the meter is on, the MENU button advances through the tests in the
following sequence: CN1, FE2, NH3, PO4, PH5, SS6, TR7. 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,
release button and allow meter to display the last test result in that MENU. Then, 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 retrieve from stored memory and display the last 20 readings in sequence
beginning with -20, which is the latest result, followed by -19, which is the 2nd latest result … finally -01, which
is the oldest result retained. Only the last 20 readings are stored in each menu. This meter is able to store
140 results in memory (20 in each menu).
3. READ: When pressed once, this button starts a 20 or 30 SECOND countdown timer depending on the
parameter being tested. If READ is pressed a second time during the countdown, the meter exits the current
timing and performs the next function.
If the parameter being measured is below or above the detection range, the display will show “LO” (Under
Range) or “HI” (Over Range), respectively. This feature is menu specific.

into the CELL and immediately press READ. This
starts the 30 SECOND countdown timer. During this
time move the strip in a gentle back and forth motion.
Because the strip is 8mm wide, the strip will need to be
angled in order to fit in the cell. Be sure test pad is fully
submerged. Remove and discard the strip after “1”
on the display disappears. The cursor will move across
the display, informing you to get ready with the CN-2 strip.
When the 30 SECOND countdown starts, dip
immediately the eXact

486812-B into the CELL. During this time, with the strip
angled slightly, move the strip in a gentle back and forth
motion. Remove and discard the strip after “1” on
the display disappears. The meter will automatically
start
to count up to 600 seconds. At 600 seconds, the

eXact® Micro 8 Tips For Best Accuracy
About the eXact® Micro 8 TR7 MENU
Become familiar with the meter and the different tests by reading the instructions carefully.
Observe the dip time (as required for the test) for accurate results.
Be sure the CELL is filled to capacity (4ml), especially for tests like pH.
Rinse the CELL with clean water immediately after completing the test. (Some test reagents will
stain or coat 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 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 100°F (38°C).
Dry the outside of the meter when testing is complete or before storage of the meter.
Each eXact
®
Strip Micro is valid for ONLY one test. Discard strip after single use in regular trash
that is inaccessible to children and pets.
Each bottle of eXact
®
Strip Micro contains the quantity of strips notated on the bottle. Due to the
manufacturing process, you may find one or two strips that are noticeably smaller or larger in
width than the normal strips in the bottle for the test. These should be discarded. Using these
strips may give unreliable results.
Each conversion table supplied has a unique revision number located in the bottom right corner of
the chart. It is recommended that you visit www.sensafe.com at least every 6 months to check for
any updated revisions for conversion chart or methodology.
Tests are calibrated at 75°F +/- 2°F (24°C +/- 1°C). If water sample is 60°F (15°C) or cooler, most
tests may require additional time for full chemical development. At the end of the normal test
procedure, press READ again and compare value after this countdown. If the new value is higher,
then use the new value for your result. When possible, it is recommended that the water sample
be warmed to room temperature before testing.
Normally the mixing cap is used for tests like Iron. A stirrer (such as a clean, plastic coffee stirrer)
may also be used in place of the mixing cap. Use the stirrer with gentle, back and forth motion,
during the 20-second countdown timing.
Our lab testing with the Micro 8 meter has shown that zeroing and measuring of the sample does
not require any cell cover for accurate results, even in full sunlight.
Remove batteries when meter is not used for more than a month.
Clean cell with 0.1N HCl before filling the meter with the sample to be tested for Iron. This is
especially important when testing low levels of Iron after running a Sulfide test, which uses an Iron
reagent. It is recommended that Iron testing be done before Sulfide testing if possible.
Rinse the CELL with clean water immediately after completing the test. A stained cell will need to
be cleaned according to procedure as described in About the Built-In Cell/Cleaning Cell (page 10).
Do not drop meter. This may cause meter to stop functioning or result in broken CELL or display.
These kinds of meter failures are not covered by the warranty.
TR7: Different ions react with a specific indicator to form a color or a precipitate that proportionally indicates the
concentration of the ion present by the transmission value found. A conversion chart is then used to determine the
ion concentration using the transmission value. The advantage of using transmission measurement is that many
different ions can be determined in one MENU, which expands the flexibility of this meter. Once you have
determined the %T result for the test you ran, find this %T result in the conversion chart and read the concentration
corresponding for this %T. The Micro 8 gives the %T values as 3 digits (example 99.2) but only the first two digits are
used in the charts (round off your %T value to two digits). Tests that can be used with the Micro 8 in TR7 MENU are
listed on page 11. Typically, common tests are supplied with the conversion chart in this booklet. For conversion
charts and information about the tests not given in this booklet, visit our website. You can also use the TR7 MENU to
develop your own custom conversion chart for unusual samples or uncommon tests
.

About The Built-In Cell/Cleaning Cell
The built-in CELL is transparent plastic and, when filled to the top, contains 4ml. The sturdy CELL design
will last for over 20,000 readings. Scratches on the CELL will not interfere or compromise the accuracy of
the readings because of its fixed position. For best accuracy, rinse cell with clean water immediately after a
test is completed. Do not use solvents, such as acetone, to clean the cell. When the CELL becomes stained
or cloudy from repeated testing, or when the meter does not blank when you press the ZERO/ON button,
the cell needs to be cleaned. Clean as follows: Fill cell with clean water and move the Cell cleaning brush
up-and-down and back-and-forth along the walls of the cell. Afterwards, rinse the cell and the meter is ready
for use again. Cleaning the cell regularly is especially recommended after you run a test that is using
turbidity or precipitation chemistry for analysis (Calcium, Potassium, Cyanuric Acid, etc.).

NOTE: Because most of our products are test strips or use reagents that have little or no hazard in the quantity sold, MSDS
sheets are not supplied with the test. The exceptions are the Manganese (486606) test, which comes with 2 strips and one liquid
reagent (PAN); Fluoride (486643) test, which is a liquid reagent (SPADNS), and Iron (481623) test, which is a powder reagent.
Hydrazine (486649), Ammonia (486654), and Sulfide (486818) use a liquid and strip.
To ensure optimal performance, store your eXact® kit in a cool, dry place away from
excess heat (below 100°F / 38°C), moisture, and oxidizers such as Chlorine and Bromine.
