Description

Description

Single test - kit Hach allows to analyze samples immediately after collection.

Use a 0 - 3,4 mg/L color disc for low to medium-range treatments. For the high range, use a color disc of 0 - 10 mg/L.

Free chlorine results - read immediately after adding a reagent to prevent interference. If the sample contains 3,0 mg/L of monochloramine (NH2Cl), then the result will increase by 0,1 mg/L every minute. Use the high range free chlorine test only if the water samples are highly chlorinated. Total chlorine results - read within 6 minutes.

The step-by-step testing procedure with the Hach CN - 80 test kit in three ranges:

  1. Place the adapter in the color comparator box - if you are testing in the range of 0 - 0,68 mg/L (the adapter shows the color in the tubes from top to bottom, place the light source above the tubes during color matching);
  2. Fill the tube with a sample:
    1. to the line in the range of 0 - 0,68 mg/L;
    2. up to 5 ml in the range of 0 - 3,4 mg/L and 0 - 10 mg/L;
  3. For the range 0 - 10 mg/L, insert the optical tube;
  4. Place the test tube - on the left in the color comparator box;
  5. Fill a glass bottle with a sample up to 25 ml ((only for a range 0 - 0, 68 mg/L and 0 - 3,4 mg/L);
  6. Add reagent powder (free or total chlorine) and swirl to mix;
  7. For free chlorine - see the result after 1 minute. For total chlorine - wait 3 minutes;
  8. Fill the second tube with ready-made samples:
    • to the upper line in the range of 0 - 0,68 mg/L;
    • up to 5 ml in the range of 0 - 3,4 mg/L and 0 - 10 mg/L;
  9. For the 0 - 10 mg/L range, insert the optical tube into the second tube;
  10. Put the tube in the color comparator box;
  11. Keep the color comparator box out in the light. (use sunlight or a desk lamp). Rotate the color disc until the colors match. If the color is between two segments, use the value in the middle of the two segments;
  12. Compare the results in the scale:
    • in the range 0 - 0,68 mg/L - divide the result by 5 to get in mg/L.
