It is a test used to measure the ions that copper (Cu2+) salts give to the water bath.
Measures the presence of copper (Cu2 +) ions in water.
Measure unit ppm. 1ppm = 1mg/l = 0,001 g/l
In the range of 0 - 3 ppm measurement is done according to the colour scale.
Water containing more copper can be measured by diluting with distilled water.
This set with natural water, well water, natural water can be measured in the tests after treatment.
Is colorimetry.
The color formed in the test is compared with the color scale and quantified.
