Product information "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.
Measuring carbonate hardness – a practical solutionWith 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.
We recommend the following
The Duroval C Titration Solution Refill Pack is a 50 ml replacement bottle for refilling your Duroval C test kit. Replacement solution for your test kit This is a titration solution for determining carbonate hardness or the m-value (acid capacity up to pH 4.3; KS 4.3) in all natural and technical water samples by titration. With the refill pack, you can replace the used-up titration solution in your existing Duroval C test kit. The solution is specially designed for determining carbonate hardness and ensures that the test kit can continue to be used. The refill bottle contains 50 ml of titration solution and is sufficient for approx. 200 analyses. The measurement time is approx. 2 minutes and the measurement accuracy is 0.5 °dH or 0.25 mmol/l. Work efficiently with the refill solution By using the refill solution, you do not need to buy a new complete kit and can carry out your analyses quickly without interrupting your testing routine.
The Duroval C Indicator 8 ml refill pack is a liquid colour indicator for use with your Duroval C test kit. It makes the point at which the reaction has finished visible, allowing you to read the carbonate hardness value. Liquid indicator for your Duroval test kit Refill pack: For determining carbonate hardness or the m-value (acid capacity up to pH 4.3; KS 4.3) in all natural and technical water samples by titration with a liquid titrant. The liquid indicator from this refill pack complements your existing Duroval C test kit, enabling you to measure carbonate hardness reliably. The indicator ensures that the chemical turning point in the titration is clearly visible, allowing you to read the measurement easily. Why the liquid indicator is important To determine the carbonate hardness or the m-value (acid capacity up to pH 4.3; KS 4.3) in all natural and industrial water samples by titration using a liquid titrant. The indicator is a crucial part of the measurement method, as it is only through its colour change that it is possible to recognise when the chemical endpoint of the titration has been reached. Without this colour change, it would be difficult to determine the carbonate hardness value.
The replacement pipette for the measurement range 0–20° dH or 0–7 mmol/l is compatible with the Duroval C and Duroval CPM test kits. It is included in the test kit set but can also be ordered as a single item. Item numbers for the compatible test kits: Duroval C: 400060 Duroval CPM: 400065 What is this pipette suitable for? The pipette serves as a suitable replacement and accessory for the aforementioned water hardness test kits. It enables precise dosing of liquids and thus supports reliable analysis of water hardness in the range from 0 to 20° dH. Areas of application: Water treatment Water hardness measurement Industrial plant monitoring Laboratory Advantages: Compatible with suitable Duroval test kits Precise dosing of analytical liquids Easy to use
