DUROVAL® A Test kit 0-60 °f

The Duroval A Titration Solution Refill Pack is a 50 ml refill bottle containing liquid titration solution for determining water hardness. Refill solution for Duroval A – for accurate water hardness measurements This refill bottle containing liquid titration solution is used to restore the Duroval A test kit to working order. The solution is used in conjunction with the test kit to determine water hardness in German or French degrees of hardness. Tests: approx. 100 (at an average hardness of 15 °dH) Measurement parameter: Water hardness Measurement range: 0–30 °dH (0–60 °f) Measurement time: approx. 2 minutes Measurement accuracy: 0.5 °dH What is the Duroval A titration solution suitable for? The refill solution is only suitable if you already own the corresponding test kit. You cannot determine water hardness using the titration solution on its own. Ideal for regular measurements The refill bottle is very practical if frequent hardness measurements are carried out and a regular supply of reagents is required.

The Duroval Indicator Refill Pack is a small bottle of liquid indicator required to restore the water hardness test kit to working order. Liquid indicator for Duroval test kits 8 ml bottle of DUROVAL® liquid indicator Refill bottle for determining water hardness across all hardness ranges. This is used in a Duroval titration test kit so that, when measuring water hardness, it is immediately apparent when the chemicals react and the result is confirmed. In combination with the titration solution, this leads to a colour change at the endpoint. This colour change allows you to determine water hardness without the need for technical equipment. What is the refill pack suitable for? The refill pack is only suitable if you already have the appropriate test kit and the colour indicator needs replacing. It is not suitable as a standalone product for measurement without a test kit. What does the liquid indicator do? The indicator ensures that the endpoint of the titration becomes visible, i.e. the exact moment when the colour change occurs. Without this colour change, it is difficult to achieve accurate results.
