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. Then, tilt meter forward to discard about 0.2mL of the cell
volume. This allows for the Pb-2 addition to be performed without overfilling the CELL.
Rinse the CELL with clean water immediately after completing the test. (Some test reagents
will stain or coat the CELL)
It is recommended that the sample be allowed to sit for 5 minutes or longer in Step 1 to
facilitate Acid reaction. Additional time would be recommended if the detection of solid Lead or
Cadmium, containing particles, are of interest.
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. Storage below 80°F (27°C) is
recomended. DO NOT REFRIGERATE TEST REAGENTS.
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. These should be discarded. Using these strips may
give unreliable results.
If conversion table(s) are supplied, they have a unique revision number. It is recommended that
you visit www.sensafe.com to check for any updated revisions and details.
Tests are calibrated at 75°F +/- 2°F (24°C +/- 1°C). It is recommended that the water sample be
warmed before testing if sample temperature is below 60°F / 16°C.
Our lab testing with the LEADQuick 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.
It is recommended that for best results this test be done on unpreserved, freshly drawn water
samples. Water samples that have been preserved with strong Nitric Acid for lead testing will
require alkali neutralization of excess acid to a pH of about 2.5; and the Acid-1 addition can be
skipped. After the Pb-2 addition step the pH should be verified if pH issue is a concern; and
ideally should be between 9.0 and 9.6 pH.
