Testoval® Nitrite kit

Refill pack: Testoval Nitrite Reagent for the rapid manual analysis of nitrite levels in water within the concentration range 0–1 mg/l NO₂. With the refill pack for the Testoval Nitrite Test Kit, you can easily continue using your existing kit. The reagents ensure that you can continue to reliably test the nitrite content in the water without having to buy a new test kit. Fresh reagents for accurate nitrite measurements The refill pack contains a complete set of reagents for the Testoval Nitrite Test Kit. The reagents are required to produce a colour reaction in the water sample; only then can the nitrite value be read on the colour comparison device. The reagents are only suitable if you already own a nitrite colour comparison device. They are not suitable for testing without the colour comparison device. Easy refilling of reagents Once the existing chemicals have been used up, they can simply be replaced with this refill pack. The test then works just as usual. The reagents allow for approximately 100 further analyses, each taking around 15 minutes to complete.

Testoval Nitrite Colour Comparison Kit or Replacement Colour Comparison Kit (without cuvette), for rapid manual analysis of the nitrite content in water within the concentration range 0–1 mg/l NO₂. The Testoval Nitrite Colour Comparison Device is the ideal measuring instrument for nitrite tests using reagents. It allows water samples to be analysed quickly and clearly by comparing the resulting colour directly with a scale. Precise analysis of the nitrite test The nitrite colour comparison device is designed to reliably read the colour reaction of a water sample. Once the water has been mixed with the reagents, a specific colour appears, and it is precisely this colour that can be compared with the integrated scale. This allows the nitrite content in the water to be reliably determined. Suitable for Testoval reagents and test kits The colour comparison device is specifically designed for the Testoval system and only works in conjunction with the appropriate reagents and test kits. It is an essential part of the measurement process, helping to ensure the results are read correctly.

The transparent replacement cuvette is a spare part suitable for all Testoval kits from Heyl. Replacement Cuvette for Testoval Test Kits from Heyl The replacement cuvette is a measuring vessel made of transparent material that serves as a sample container in chemical analyses. It is particularly used for manual test kits where a defined quantity of a water sample or reagent is required, for example in colorimetric analyses or titrations. Why buy the replacement cuvette from Heyl? Precisely fitting for all TESTOVAL test kits from Heyl Transparent design Reusable Cost-effective replacement Possible applications of the cuvette The cuvette can be used together with manual water analysis test kits, especially the Heyl Testoval kits. It is used wherever a defined and repeatable sample intake is required, e.g. for color comparison reactions or photometric measurements in handheld test devices.
