The reagents must react precisely for a water analysis to be reliable. New reagents ensure that the colour change remains clearly visible and that the measured chloride value is accurate.

Duroval CO₂ Test Kit by Heyl – CO₂ Measurement Made Easy Quick Determination of Dissolved CO₂ The Duroval CO₂ test kit is designed for determining dissolved carbon dioxide in water samples. With this kit, you can reliably measure free carbonic acid in water using drop titration. Quick and Reliable Determination of Dissolved CO₂ in Water The Duroval CO₂ test kit enables precise measurement of dissolved carbon dioxide (free carbonic acid) in water samples. Using the proven drop titration method, CO₂ levels can be determined quickly, easily, and reproducibly. The kit is ideal for applications in water treatment, drinking water monitoring, industry, and technical operations where CO₂ content directly affects water chemistry and material durability. Why Measuring Carbon Dioxide (CO₂) in Water is Important Dissolved carbon dioxide significantly affects the pH, corrosiveness, and chemical stability of water. Excess CO₂ can cause corrosion in pipes, fittings, and system components, especially metallic materials. Additionally, CO₂ plays a key role in the lime-carbonic acid equilibrium. Imbalances can promote both scaling (lime deposits) and material degradation. Regular measurement of free CO₂ allows for targeted water treatment, optimized dosing, and prevention of system damage. The Duroval CO₂ test kit therefore supports safe process management, stable water quality, and long-term protection of water-carrying systems.

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.

The Duroval TI Titration Solution Refill Pack (25 ml bottle) for refilling your existing Duroval TI test kit. For determining water hardness in the range 0–30 °dH (0–60 °f).

The Duroval TI with pipette (0–60 °f) is a titration test kit for determining water hardness. With its liquid indicator and calibrated pipette, it delivers rapid results. Precise water hardness analysis with the Duroval test kit With the Duroval test kit, you can reliably determine the hardness of your water in French degrees of hardness without an electronic measuring device.

Tests: approx. 60 (based on an average hardness of 26.7 °f) How does the test kit work? The Duroval method allows for a quick and straightforward determination of the total hardness of water, without the need for any additional equipment. In hard water, the indicator initially turns a deep red. When the titration solution is then added, it binds the hardness components, causing the colour to change from red to green. The volume of titration solution dispensed using the measuring pipette up to this colour change corresponds to the hardness of the water sample. The total hardness value can be read directly from the measuring pipette.
