To order individual reagents or test kit components, use the specifi ed code number.
Carefully read the LaMotte Direct Reading Titrator Instruction Manual (1649) before
proceeding. The Titrator is calibrated in percent available chlorine; each minor
division equals 0.2 percent.
NOTE: If endpoint is not achieved after one full Titrator of reagent has been added in
the titration, refi ll and zero the titrator to continue titration beyond 10 percent.
PROCEDURE
1. Fill test tube (0778) to 10 mL line with tap water.
2. Use the 0.5 mL pipet (0353) to add 0.5 mL of sample to the test tube containing
tap water from Step 1.
3. Use the 1.0 mL pipet (0354) to add 1.0 mL of *Hypochlorite Reagent A (7939).
Swirl to mix.
4. Use 0.1g spoon (0699) to add 0.1g Potassium Iodide Crystals (6809).
Swirl to mix.
5. Fill the Direct Reading Titrator (0377) with Hypochlorite Reagent D (2790). See
Direct Reading Titrator Manual (1649). Insert the Titrator tip into the center hole
of the test tube cap.
6. While gently swirling the tube, slowly depress the plunger to titrate the sample
until the solution changes from brown to colorless and remains colorless for one
minute. Read the test result directly from the scale where the large ring on the
Titrator meets the Titrator barrel. Record as Percent Chlorine.
NOTE: The solution will go through an intermediate yellow stage.
