K-9815 Total Alkalinity

K-9815 Total Alkalinity Kit is used to determine Alkalinity levels from 50-500 ppm as CaCO3

Alkalinity Information


The K-9815 Total Alkalinity Kit was designed to accurately measure the total alkalinity levels in water from 50-500 ppm. K-9815 uses an acid titrant with pH indicatorCHEMetrics' total alkalinity tests determine total or M alkalinity using a hydrochloric acid titrant and a bromocresol green/methyl red indicator. The end point of the titration occurs at pH 4.5. Results are expressed as ppm (mg/L) CaCO3.

The alkalinity of water is a measurement of its buffering capacity. Alkalinity of natural waters is typically a combination of bicarbonate, carbonate, and hydroxide ions. Sewage and wastewaters usually exhibit higher alkalinities due to the presence of silicates and phosphates. Alkalinity inhibits corrosion in boiler and cooling waters. It is also measured as a means of controlling water and wastewater treatment processes or the quality of various process waters.

What's included:

  • 30 Ampoules with valve assemblies
  • Activator Solution
  • Titrettor
  • 25 mL Sample Cup
  • Instructions



How to use:

  1. Add 20 mL of sample into the empty sample cup. Fill the sample cup to 25ml  

  2. Add 6 Drops of Activator solution. Stir gently.
  3. Snap the tip of the ampoule at the black snap ring.

  4. Lift the control bar and  insert the Titret assembly into the Titrettor.

  5. Hold the Titrettor with the sample pipe in the sample. Press the control bar firmly, but briefly, to pull in a small amount of sample. Contents will turn PINK. Wait 30 seconds.
  6. Repeat, mixing the assembly between each sample draw. 

  7. Tip the vacu-vial back and forth to mix
  8. Press the control bar again and mix the ampoule. Watch for color change from PINK to BRIGHT GREEN. 
  9. Repeat until the change to BRIGHT GREEN is permanent to remove the ampoule and obtain results.
