To order individual reagents or test kit components, use the specifi ed code number.
This test set provides total alkalinity readings only.
Read LaMotte Direct Reading Titrator Manual before proceeding. The Titrator is
calibrated in terms of total alkalinity expressed as parts per million (ppm) Calcium
Carbonate (CaCO3). Each minor division on the Titrator scale equals 4 ppm CaCO3.
WARNING! This set contains chemicals
that may be harmful if misused. Read
cautions on individual containers
carefully. Not to be used by children
except under adult supervision

Result:
Read the test
result directly from
the scale where the
large ring on the
Titrator meets the
Titrator barrel. Record
as ppm Total Alkalinity
in ppm Calcium
Carbonate (CaCO3).

NOTE :
If the plunger tip reaches the
bottom line on the scale
(200 ppm) before the endpoint
color change occurs, refi ll
the Titrator and continue the
titration.
When recording the test result,
be sure to include the value of
the original amount of reagent
dispensed (200 ppm).
