- Measuring tube
- Calibrated dosing pipette
- Special connecting stopper
- 8 ml indicator
- 50 ml titration solution
Reliable Titration for Determining Acid Capacity up to pH 4.3
The Duroval KS 4.3 titration kit allows precise determination of acid capacity up to pH 4.3 and is specially designed for monitoring water quality in pools and spas. Acid capacity is an important parameter for assessing the water’s buffering capacity and for safely adjusting the pH value.
With its proven titration method, the kit delivers quick and reliable results, making it ideal for regular use during operation.
Advantages of Duroval KS 4.3 for Swimming Pool Water Analysis
Duroval KS 4.3 stands out for its ease of use and high measurement reliability. The clearly readable, calibrated dosing pipette enables precise dosing of the titration solution, while the clear color change of the indicator ensures safe evaluation.
The compact kit is perfect for routine checks and helps operators maintain stable water quality, dose chemicals correctly, and ensure long-term swimming hygiene.
Analyses: approx. 100 (at an average acid capacity of 1 mmol/l)
Frequently asked questions
The shelf life is printed on the label of each product. Upon delivery, the guaranteed shelf life is at least 7 months.
That depends on the specific item to be ordered. For Testoval products, only the complete refill pack can be ordered. The individual small bottles cannot be reordered separately. For the Duroval test kit, the individual components of the refill pack can also be reordered separately.
Yes, this is possible for the Duroval product range.
The safety data sheet can be found directly with the product in our shop or separately in the download area under the relevant heading.
Disposal instructions can be found in section 13 of the safety data sheet. Disposal must be carried out in accordance with official regulations.
No, the chemicals can no longer be used after the expiry date. After the expiry date, accurate measurement results can no longer be guaranteed.
Section 7 of the safety data sheet contains all relevant information on the storage of chemicals. The recommended storage temperature should be between 15-25°C.

The Duroval Ks 4.3 Indicator 8 ml refill pack is a colour-changing indicator for titration measurements to determine the acid capacity in water samples up to pH 4.3. Reliable monitoring of acid capacity in water samples The indicator enables reliable titration measurements. Thanks to a clear colour change, it is indispensable for correctly determining acid capacity. Particularly in all natural and technical water samples, it helps to monitor water quality and prevent damage caused by incorrect pH values. Suitable for: Duroval titration kit for acid capacity measurement (pH 4.3) Routine checks Repeated measurements Not suitable for: Use without the appropriate test kit Independent water analysis without titration Applications outside chemical titration procedures Why is a functioning indicator crucial? It is only through the colour change produced by the indicator that the exact endpoint of the titration can be identified. Without it, the measurement results become unreliable, which can lead to misinterpretations of water quality. With the refill pack, your test kit is ready for use again without you having to buy a new set.
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). Precise measurement of carbonate hardness and acid capacity 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.
