.
4. Scroll to and select
21 Chloride-TesTab
from menu.
5. Rinse a tube (0290) with sample water. Fill to 10 mL with sample.
6. Insert the tube into chamber, close lid and select

.
7.
Remove the tube from Spectro.
8. Add one *Chloride Spectrophotometric Grade Tablet (3885A).
9. Use Tablet Crusher (0175) to crush tablet.
10. Cap tube.
11. Invert 2 times.
12. Wait 3 minutes. Do NOT mix.

. Record result in ppm
chloride.
14. Press and hold
OFF
button to turn the colorimeter off or press
EXIT
button to exit to a
previous menu or make another menu selection.
NOTE: For best possible results, a reagent blank should be determined to account for any
contribution to the test result by the reagent system. To determine the reagent blank,
follow the above test procedure to scan a distilled or deionized water blank. Then follow
the above procedure to perform the test on a distilled or deionized water sample. This test
result is the reagent blank. Subtract the reagent blank from all subsequent test results of
unknown samples.
The reagent system is temperature sensitive. The calibration is for 25ºC. If sample is at
30ºC, multiply resulting ppm by 1.1. If the sample is at 20ºC, multiply resulting ppm by 0.9.
