Original Heyl reagents for precise iron determination in the low measurement range The measurement range covers 0–1 mg/L Fe. Individual values of 0.05 mg/L, 0.1 mg/L, 0.25 mg/L, 0.5 mg/L, 0.75 mg/L, and 1.0 mg/L can be safely read using optical color comparison. As an original Heyl product, the reagents are precisely matched to the Testoval Iron test kit, ensuring consistently reliable results. Advantages of the Original Heyl Refill Reagents for Testoval Iron The refill pack allows for approximately 100 analyses, with a measurement time of about 7 minutes per sample. This makes the set an economical and efficient solution for regular iron analyses in drinking, process, and industrial water. By diluting the water sample at a 1:10 ratio with distilled water, the measurement range can be flexibly extended up to 10 times the iron concentration. Using original Heyl reagents ensures consistently high measurement quality, maximum compatibility, and reliable water analysis. Frequently asked questions How long do Heyl chemicals last? The shelf life is printed on the label of each product. Upon delivery, the guaranteed shelf life is at least 7 months. Can Heyl reagents also be purchased individually?

Yes, this is possible for the Duroval product range. Where can I find the safety data sheet? The safety data sheet can be found directly with the product in our shop or separately in the download area under the relevant heading. How can the chemicals be disposed of? Disposal instructions can be found in section 13 of the safety data sheet. Disposal must be carried out in accordance with official regulations. Can the chemicals still be used after the expiry date? No, the chemicals can no longer be used after the expiry date. After the expiry date, accurate measurement results can no longer be guaranteed. How should Heyl chemicals be stored? 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.

Testoval Iron 0-1 mg/L Test Kit ||/||| - Precise Iron Analysis Rapid iron determination with clear color reaction The Testoval Iron 0-1 mg/L color comparison kit is used to determine the iron content in water within a concentration range of 0-1 mg/L Fe. Individual values of 0.05 mg/L, 0.1 mg/L, 0.25 mg/L, 0.5 mg/L, 0.75 mg/L, and 1 mg/L can be read using an optical color comparison. The kit includes two reagents and a color comparison device for simple concentration determination. The color comparison kit enables reliable detection of low iron concentrations in water. By diluting the water sample at a 1:10 ratio with distilled water, the measurement range can be extended up to ten times. Fast and reliable determination of low iron concentrations in water The test kit is ideal for applications where low iron levels need to be reliably monitored, such as drinking water monitoring, water treatment, or technical installations. Advantages of the Testoval Iron 0-1 mg/L Test Kit The color comparison kit allows for a simple and rapid manual analysis of iron content with a clearly visible color reaction. The included color comparison device supports accurate evaluation and reduces user errors. By diluting the water sample at a 1:10 ratio with distilled water, the measurement range can be flexibly extended up to 10 mg/L Fe. This makes the test kit highly versatile and suitable for both routine checks and extended analyses. Frequently asked questions How long do Heyl chemicals last?

Iron 0–1 mg/l - Color Comparator Testoval - Concentration range 0–1 mg/l Fe The color comparator is a replacement device for the Testoval Iron 0–1 mg/l test kit (II) + (III) from Heyl and is used for the visual determination of iron in water samples. Reagents are not included in the scope of delivery. The Testoval color comparator for iron (0–1 mg/l) is used for the visual determination of iron in water samples. After adding the appropriate reagents, a characteristic color reaction occurs, which is compared with the integrated color scale in the device. This allows the iron concentration to be read quickly and easily. The device is used as a replacement unit for the Testoval iron test kit and enables manual water analysis without electronic measuring devices. By diluting the water sample in a ratio of 1:10 with distilled water, the measuring range can be extended to ten times the concentration. Technical Data Analyses: approx. 100 Measurement time: approx. 7 minutes The individual values 0.05 mg/l, 0.1 mg/l, 0.25 mg/l, 0.5 mg/l, 0.75 mg/l and 1 mg/l can be read by optical color comparison. Possible application areas of the color comparator Thanks to its compact design, it is suitable for both laboratory analyses and mobile on-site measurements. The color comparator is also ideal for monitoring iron in well and groundwater as well as for supervising water treatment systems. Advantages of the Testoval Iron 0–1 mg/l (II) + (III) from Heyl The determination of ferrous and ferric iron is carried out quickly and easily via optical color comparison. The iron content in the water sample can be reliably determined without the use of electronic measuring devices. The scope of delivery includes only a color comparator for simple concentration determination. Replacement reagents & the complete colorimetric test kit are also available in our shop.
