CHECKIT Test Kits CHECKIT? Comparators? Supplied field-ready in a carrying case with reagents and accessories for 30 tests Wide range of parameters for a variety of applications Colour discs have a continuous colour gradient making it possible to achieve a direct colour match - no need to extrapolate the result between two colour standards CHECKIT??Comparator Test Kits are accurate, easy to use test kits for water analysis. Simply add the reagent to the sample cell, rotate the disc until the colour matches the prepared water sample and read the concentration value. An example fo how to use these kits is shown below: ?

Beer-Lambert Law A sample becomes more saturated with colour as the path length or concentration increases. (Specifically, the relationship of the absorption of light to the properties of the material through which the light is travelling). The diagram below shows Platinum Cobalt solution of 500 in various path length cells: ? ? The cells used are, from left to right: 6", 5.25", 100mm, 3", 50mm, 40mm, 1", 20mm, 10mm, 1mm. ? ? ? ? ? The exact same sample in a 6" cell appears vastly different to that in the 1mm cell. As can be clearly seen, the saturation of the colour increases with the path length. The same is true when the concentration of a sample increases, then so does the saturation of the colour. This proves the importance when communicating colour: it is essential to specify the path length of the cell. Feefo Reviews Related Blogs Can I expand my Checkit Test kit to measure other parameters?
