pH 6.5-8.5 (with Acid & Base Demand)

Range(s): 6.50-8.50

Colorimeter Series

Instruction #5859

Procedure

Note: When testing multiple samples simultaneously, a

separate sample cell with an unreacted sample of the

water tested must be used to zero the colorimeter.

Please note that varying the test procedure from the

original can affect the precision of the test.

1. Turn on the Colorimeter.

2. Select a test menu (ALL TESTS, RECENT TESTS, or

FAVORITES) containing pH 6.5-8.5 using .

3. Select pH 6.5-8.5 using  ; then press ENTER .

4. Rinseandll25mmsamplecellto10mLmarkwith

sample; then cap.

5. Insert sample cell into sample cell compartment. Align

marksperUser’sManual.

6. Select ZERO using ; then press ENTER . Zero

will be displayed.

7. Remove sample cell from sample cell compartment;

then remove cap.

8. Add0.5mLpH6.5-8.5-ReagentA;thencapandswirl

to mix thoroughly.

9. Insert sample cell into sample cell compartment. Align

marks.

10. SelectREADusing; then press ENTER . The

instrument will read the sample and the result will be

displayed.

2. Add 1 drop pH 6.5-8.5 - Reagent B to sample cell.

Cap and swirl to mix.

3. Insert sample cell into sample cell compartment. Align

marks.

4. Press ENTER . The result will be displayed.

5. Continue adding Reagent B dropwise until desired pH

is reached.

6. Record number of drops dispensed and refer to Acid

2. Add 1 drop pH 6.5-8.5 - Reagent C to sample cell.

Cap and swirl to mix.

3. Insert sample cell into sample cell compartment. Align

marks.

4. Press ENTER . The result will be displayed.

5. Continue adding Reagent C dropwise until desired pH

is reached.
