Find the “TR” result in the table below to determine the Iron concentration in ppm (parts per
million). (Example: a “TR” result of 85.3 (use only the 85 for the chart) equals an Iron value of
0.37 ppm). Record result. After testing is completed, rinse cell immediately.

at least 3 times with the water sample you will be testing - rinsing minimizes
the potential for cross-contamination from a previous test. Finally, fill cell to capacity (4ml)
with the water sample. In order to leave room for powder reagent, do not overfill cell.

Add the contents of one
eXact
®
Reagent Iron Ferro Powder Pillow, Part No. 481623
to the
CELL
and cap meter cell with mixing cap. Press
READ
to start the timer, mix the sample by
pressing one finger over the cap to keep it in place. Then, turn the meter over from side to side
to mix during the 20 second countdown.
When time displays 1
, hold the meter upright and the
cursor will move across the display, informing you that it is about to measure the sample. Time
the reaction in the cell for an additional
three (3) minutes
(timer not included). During this time,
meter will shut off. When
3 minutes
have elapsed, turn meter on and wait for the display to
show last reading. Then, press
READ
, which will start a final
20 SECOND
countdown. The
cursor will move across the display, informing you that it is about to measure the sample.
Record result displayed (this result is automatically stored in TR7).
ADD REAGENT, CAP, PRESS “READ”, AND MIX

NOTE:
Water samples with suspended solids and particulates may cause incorrect results, since the reducing agent in the
powder pillow often dissolves the suspended solids and particulates. If the meter is zeroed with the original water sample
the zero is no longer valid for this kind of sample. So, for this kind of sample, zero the meter using a water sample free of
suspended solids and particulates (use distilled, deionized, or bottled water in Step 4). Then, rinse the cell three times with
the water sample you will be testing, and finally fill the cell with this water sample. Continue with Steps 5 and 6 as directed.

Find the “TR” result in the table below to determine the Fluoride concentration in ppm (parts per
million). (Example: a “TR” result of 3.42 (use only the 3.4 for the chart) equals a Fluoride value
of 0.9 ppm). Record result. After testing is completed, rinse cell immediately. For all values
with a Transmission above 5.00%, the Fluoride level is greater than 1.1 ppm. For all samples
above 1.1 ppm, it is recommended that the sample is diluted with distilled or deionized water
and retested.
