DUROVAL® KS4,3 indicator refill pack

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.

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.
