This involves taking a sample of solution and then counting the number of drops of reagent that need to be added to cause a colour change. The number of drops added is then looked up in the instruction leaflet and will give a reading of mg/Litre.
The Colorimetric method.
Here the concentration is directly proportional to the intensity of the colour after the addition of a known volume of reagent to the sample. The resulting colour is then checked against a colour chart giving the results in ppm or mg/litre .
We can supply Individual kits to test
for just one parameter such as acidity,
alkalinity or specific chemicals such as
Kits that cover a range of Parameters.
