Test kit for the determination of the carbonate hardness or the m-value (acid capacity up to pH 4,3; Ks4,3) of all natural and industrial water samples via titration with a liquid titration agent and a pipette with accurate °dH and mmol/l calibrations.


  • Complete with measuring tube, pipette with calibration 0-20 °dH and 0-7 mmol/l, special junction stopper, indicator and 50 ml titration solution.
  • Analyses: approx. 100 (at an average carbonate hardness of 10 °dH)
  • Measuring time: approx. 2 minutes
  • Accuracy: 0.5 °dH / 0.25 mmol/l.
