Calcium Hardness Test Procedure
1
Remove one (1)
eXact
®
Strip Micro CA
, part number 486629, from the bottle before
beginning the test. Set the strip in a dry, convenient place and recap the bottle immediately.

Dip the
eXact
®
Strip Micro CA, Part No. 486629
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.
Remove and discard the strip when the time displays 1
. 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 CA5). After testing is completed, rinse cell
immediately.
DIP STRIP AND PRESS “READ”

Press the
ZERO/ON
button. The cursor will move across the display, followed by

Press and re-press the
MENU
button until the display shows the parameter
CA5
.
SELECT TEST: CA5

Rinse the
CELL
2 or 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.

Copper Test Procedure
CA5: Calcium reacts with Oxalic acid as it is released from the strip to form a white precipitate, directly
proportional to the Calcium concentration. Values are reported as Calcium Carbonate.
CU6: Copper reacts with Biquinoline or Bicinchoninic Acid as it is released from the strip to form a purple color,
directly proportional to the copper concentration.

Find the “TR” result in the table below to determine the Chromate concentration in ppm (parts
per million). (Example: a “TR” result of 66.3 (use only the 66 for the chart) equals a Chromate
value of 0.52 ppm). Record result. After testing is completed, rinse cell immediately.
