Description

Description "DUROVAL® C indicator refill pack"

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.
