per million (ppm) Calcium Carbonate (CaCO
3
). Each minor division on the Titrator
scale equals 4 ppm CaCO

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).
Read the test result
directly from the
scale where the large
ring on the Titrator
meets the Titrator barrel.
Record Total Alkalinity as ppm
Calcium Carbonate (CaCO
3
).
Insert the Titrator
into the center hole
of the test tube cap.
While gently
swirling the tube,
slowly press the
plunger to titrate
until blue-green
color changes
to pink.
Fill Direct
Reading
Titrator
(0382) with
*Alkalinity
Titration
Reagent B
(4493DR).
Cap and
mix.
Solution
will turn blue-green.
Add 4 drops
of *BCG-MR
Indicator
(2311-EG).
Fill the test
tube (0608)
to the 5 mL
line with the
sample water.
