About Checker (2) Hanna Instruments HI755-26 Reagent
CALIBRATION PROCEDURE: Turn the meter on by pressing the button, all segments will be displayed. When the display shows ‘’Add’’, ‘’C.1’’ with ‘’Press’’ blinking, the meter is ready. Fill the cuvette to the 10 mL line on the cuvette with unreacted sample and replace the cap. Place the cuvette into the meter and close the meter’s cap. Press the button. When the display shows “Add ”, “ C.2 ” with “ Press ” blinking the meter is zeroed. Note: Any chlorine present in the sample will interfere with the reading. To remove the chlorine interference add one drop of HI 93755-53 Chlorine Remover to the unreacted sample. Remove the cuvette, open it and using a 1 mL syringe carefully add exactly 1.00 mL of Alkalinity Reagent to the sample. Replace the cap and gently invert 5 times. Place the cuvette back into the meter. Note : Pay attention not to spill reagent otherwise full color development may be inhibited. Press the button. The instrument directly displays the concentration of alkalinity in ppm of CaCO3 . Alkalinity conversion: 1 ppm CaCO 3 = 0.02 meq/L = 0.056 dkH The meter automatically turns off after 10 minutes.
