  • Page 8: Safety Information For The Correct Use Of The Instrument

    The TitraLab pH & Alkalinity content system is used for the titrimetric determination of alkalinity in waters. Intended for the analysis of natural, treated water and waste water.

  • Page 9: Front And Back View

    General information • TitraLab can be used directly for waters having an alkalinity concentration of up to 20 mmol/L. For samples containing higher concentrations of alkalinity, a smaller test portion can be used for analysis. The recommended lower limit is 0,4 mmol/L.
