PRO CE DURE
1.
Fill the test tube (0778) to 5 mL line with sample water.
2. Add one BCG-MR Indicator Tablet (T-2311). Cap and shake until
dissolved. A blue-green color will develop.
3. Fill the Direct Reading Titrator (0382) with *Alkalinity Titration
Reagent B (4493DR). Insert Titrator into the center hole of the test tube
cap.
4. While gently swirling the tube, slowly depress plunger to titrate until the
blue-green color changes to pink. Read the test result where the plunger
meets the titrator scale. Record results as Total Alkalinity in ppm
(CaCO
3
).
NOTE: Each minor division on Titrator scale = 4 ppm Total Alkalinity
as CaCO
3
.
EXAMPLE: Plunger tip is 3 minor divisions below line 140. The test
result is 140 plus (3 divisions x 4) equals 152 ppm.
5. If the plunger reaches the bottom line on the titrator scale (200 ppm)
before the endpoint color change occurs, refill the titrator and continue
titration. When recording the test result, be sure to include the value of
the original amount of reagent dispensed (200 ppm).
When testing salt water aquariums, alkalinity may be called carbonate
hardness. Multiply ppm Alkalinity by 0.056 to convert to German degrees
of Hardness.
This test set provides Total Alkalinity readings only. For comprehensive
analysis of Phenolphthalein (P), Total (T), Hydroxide, Carbonate, and
Bicarbonate Alkalinity the Model WAT-MP-DR Test Set, Code 4533-DR
is recommended.
