Duroval KS 4,3 titration solution

Heyl’s Duroval KS 4.3 titration solution is a ready-to-use refill solution for Duroval test kits. It is used for the precise determination of carbonate hardness or the m-value (acid capacity up to pH 4.3; KS 4.3) and, in combination with other Duroval components, can also measure the p-value (acid capacity up to pH 8.2; KS 8.2).

The Duroval KS 4.3 titration solution is used as a component of the Duroval test kits and enables precise titration measurements of both the m-value (pH 4.3) and the p-value (pH 8.2). This allows water samples to be reliably tested for acid capacity and carbonate hardness. The solution is similar to Duroval C, but also contains a p-value indicator for extended analysis ranges.

Suitable for:

• Duroval titration kits for measuring m-value and p-value
• Routine checks in laboratories, swimming pools and technical facilities
• Use in combination with indicators and measuring tubes for reproducible results

Not suitable for:

• Use without the appropriate test kit
• Rapid tests without titration
• Measurements outside chemical titration procedures

Why is the correct titration solution crucial?

The Duroval KS 4.3 titration solution ensures that chemical reactions in the test system reach a clear endpoint, allowing the m-value and p-value to be determined reliably. Only with a high-quality, precisely dosed solution can the endpoint be visualised and the acid capacity calculated correctly.
