LaMotte OAKITE ALKALINE TEST KIT OKT 9205 - Manual (Page 10)

Test Kit Procedure 123 continued
Example:
A B A-B A+B
A-B
A+B
1st Titration (fresh tank) 1.75 .025 1.50 2.00 0.75
2nd Titration (after use) 1.50 0.50 1.00 2.00 0.50
3rd Titration (after much more use) 1.00 1.00 0.00 2.00 0.00
NOTES:
*1. For complete instructions on how to use the Direct Reading Titrator please refer to the
enclosed instruction sheet.
2. The ratio is constant and specific for fresh solutions of each Oakite product regardless of the
absolute concentration used.
3. The ratio reduces with use. As the ratio approaches zero it indicates a spent tank.
4. A suggested sample volume for highly concentrated alkaline solutions is 1 ml and for weaker
solutions, up to 10 ml.
5. The ratio of Free to Total Alkali should first be determined on a fresh solution. An appropriate
sample volume should be chosen so as to yield a Titration “A” somewhere between 1 and 2
ml of 1N Acid in Step 3.
6. Once the appropriate sample volume has been chosen, it must remain constant for
subsequent titrations of the Oakite solution after use.
