DUROVAL® C

The Duroval C test kit is an analysis kit for determining the carbonate hardness of water samples. It delivers reliable results within a few minutes.

With the Duroval C test kit, you can determine the carbonate hardness or the m-value (acid capacity up to pH 4.3; KS 4.3) in natural and technical water samples by titration using a liquid titrant and a dosing pipette precisely calibrated in °dH and mmol/l. Complete with measuring tubes, dosing pipette calibrated to 0–20 °dH and 0–7 mmol/l, special connecting stopper, indicator and 50 ml titration solution. This allows for up to approx. 100 analyses to be carried out at an average carbonate hardness of 10 °dH. The measurement time is approx. 2 minutes and the measurement accuracy is 0.5 °dH.

How the measurement works

Pour the water into the test tube, then add the titration solution drop by drop using the pipette, observing the colour change as you do so. Once the chemical endpoint is reached, you can read the carbonate hardness value in °dH or mmol/l.
