Directions for KH Alkalinity Pro Test Kit
1. Using the large syringe provided, place exactly 10 ml of the water to be tested into
the glass vial.
2. Screw the glass vial onto the bottom of the Titrator.
3. Ensure that the dispensing tip is on the 1 ml titration syringe and fill with 1ml of
Alkalinity Pro Titrant. [see note for filling titration syringe.]
4. Insert the syringe into the center of the Titrator so that the volumetric scale on the
side of the syringe is visible. The graduations of the volumetric scale are 0.01 ml,
equivalent to an alkalinity of 0 .05 meq/L (0.14 dKH).
5. Add the first 0.4 ml of titrant (equivalent to an alkalinity of 2.0 meq/L – 5.6 dKH) by
pressing the plunger of the syringe while gently swirling the Titrator. The test sample
will obtain the titration start color as shown on the instruction card after the first few
drops of titrant are added. Continue adding the titrant gradually, swirling the Titrator
after each addition and paying attention to the color in the vial. As the color in the
vial approaches the end color as shown on the instruction card, add one drop at a
time, swirling after each drop, until the end color is achieved.
Note: If you have added 1 ml of alkalinity titrant, without reaching the end color, the
alkalinity of your water sample is more than 5 meq/L (14 dKH). Refill the syringe and
continue to add titrant until you reach the end color.
6. Note the amount of titrant used (according to the initial and final position of the
plunger not the liquid surface) and use the table on the instruction card to calculate
the level of alkalinity in the water sample.
7. Dispose of any unused quantity of titrant.
