DUROVAL Chloride Test Kit for determining the chloride content in water. Complete with all reagents and accessories. Suitable for approx. 200 analyses. The Duroval Chloride Test Kit is a complete measurement system for determining the chloride content in water. The kit contains all necessary reagents, accessories and a calibrated pipette. Within approx. 2 minutes, the kit shows how much chloride is present in your water sample. Simple chloride measurement – quick and reliable The supplied calibrated titration pipette is calibrated for a range of 0 to 300 mg/l chloride and, together with the reagents, enables accurate measurement with a resolution of 10 mg/l Cl⁻. This product is classified as a hazardous substance. Please refer to the safety data sheet. Combine the sample and reagent, add drops using the pipette and identify the endpoint by the colour change. Suitable for: • Measuring the chloride content in natural or industrial water samples • Applications requiring simple, convenient measurement without the need for a laboratory Not suitable for: • Measurements without a complete test kit • Rapid tests without chemical titration • Applications outside the measurement range Why is chloride measurement important? (h3) Chloride is highly corrosive to metals in water and can therefore damage pipes, heat exchangers, boilers and membranes. Regular monitoring ensures that specified limit values in heating, cooling, boiler and water treatment systems are adhered to and that the system operates reliably. Product features: (h3) Analyses: approx. 200 Measurement time: approx. 2 minutes Titration pipette: calibrated 0–30 mg/l Cl⁻ Measurement accuracy: 10 mg/l Cl⁻

Testoval Chloride Reagents Refill Pack – precise and fast measurement results This product is a refill pack for the Testoval Chloride test kit from Heyl. The reagents allow for approximately 40 analyses. The Testoval Chloride reagents refill pack is used to replenish existing Testoval Chloride test kits for manual water analysis in the concentration range of 0–100 mg/l Cl. With the included reagents, the chloride content in water can be determined quickly and reliably. During the analysis, the water sample reacts with the reagents and produces a measurable color change. This is then compared with the color scale of the Testoval color comparator, allowing the chloride value to be read easily. The individual values 1 mg/l, 5 mg/l, 10 mg/l, 25 mg/l, 50 mg/l and 100 mg/l can be read by optical color comparison. The refill pack contains a complete set of reagents and enables approximately 40 analyses without the need for a new test kit. Advantages of the refill pack for the chloride test kit from Heyl easy storage and transport suitable for regular routine analyses enables refilling of existing Testoval Chloride test kits Possible application areas environmental analyses and quality controls drinking water monitoring water treatment plants laboratory examination of water samples

Testoval Chloride Test Kit – Manual Analysis of Chloride Content Color comparison test kit from Heyl for fast manual analysis of the chloride content in water in the concentration range of 0–100 mg/l Cl. The Testoval Chloride Test Kit is a color comparison analysis device for the fast manual determination of chloride content in water. The measurement is carried out by a chemical reaction with reagents that produces a color change. The sample is then compared with a scale in the color comparison device, allowing the chloride value to be read easily. In addition to the two reagents, the scope of delivery includes a color comparison device for simple concentration determination. Technical Data for the Chloride Test Kit from Heyl The individual values 1 mg/l, 5 mg/l, 10 mg/l, 25 mg/l, 50 mg/l and 100 mg/l can be read by optical color comparison. Number of possible analyses: approx. 40 Measurement time: approx. 3 minutes Advantages of the Color Comparison Test Kit from Heyl no electronic measuring devices required suitable for routine checks of water samples provides clear and easy-to-read results complete test set with reagents and color comparison device Possible Application Areas of the Testoval Chloride Test Kit laboratory analyses and quality controls water treatment plants drinking water monitoring environmental and water analysis Also Available in Our Shop: Item number: 410527 Testoval Chloride Reagents Refill Pack Item number: 410528 Chloride color comparison device Testoval

Chloride Color Comparator Testoval from Heyl Replacement color comparator Testoval Chloride without cuvette, for fast manual analysis of chloride content in water in the concentration range of 0–100 mg/l Cl. The Testoval color comparator for chloride is an analysis device for the visual determination of chloride concentration in water samples. It is used in combination with the appropriate reagents and enables quick and easy evaluation via optical color comparison. After the chemical reaction of the water sample with the reagents, a characteristic color change occurs. This is compared with an integrated color scale in the comparator, allowing the chloride content to be reliably determined. The device is suitable as a replacement or additional unit for the Testoval Chloride test kit and supports manual analyses without electronic measuring systems. Technical Data of the Chloride Color Comparator Testoval from Heyl Number of analyses: approx. 40 The individual values 1 mg/l, 5 mg/l, 10 mg/l, 25 mg/l, 50 mg/l and 100 mg/l can be read by optical color comparison. Measurement time: approx. 3 minutes Advantages of the Heyl Color Comparator simple determination of chloride content through visual color comparison clear color scale for fast evaluation suitable as a replacement device for the existing Testoval Chloride test kit enables fast routine analyses of water samples Possible Application Areas drinking water analysis industrial and environmental analytics control of chloride levels in technical water systems laboratory analyses and quality control The scope of delivery includes only a color comparator for simple concentration determination. A set of reagents for approx. 40 analyses or a complete kit can be ordered separately.
