Instructions for use
1. Pull out the line at the tip of the tube
2. Drive out the air in the tube.
3. Insert into the water to be tested and stop when about half of the water is inhaled.
4, shaking 5-6 times, in the specified time, with the standard color card color.
Color card instructions
According to the instructions, take a certain amount of liquid to be tested and place it in a test tube.
In the case of A colorimetry, first place the color chart flat in a well-lit area.
B colorimetric tube is placed vertically above the color chart (see instructions)
The C tester observes the colorimetric color through the liquid surface and finds the same color gradation as the color of the liquid in the tube, which is the parameter to be tested.
In aquaculture, environmental analysis, wastewater discharge and treatment, industrial water, printing and rinsing, chemical and light
Work, plating surface treatment, and water quality analysis in swimming pools are widely used.
Influence of coexisting substances
In the presence of strong oxidants, color changes may also occur. Such as residual chlorine, ozone and other oxidizing substances
1. If the pH of the solution to be tested is not within the range of 6-9, neutralize it with dilute sulfuric acid or dilute sodium hydroxide.
2. When the concentration of peracetic acid exceeds 100 mg/L, the color development becomes weaker with the increase of the concentration. For example, when 600mg/LH2O2, the color is equivalent to the concentration of peroxyacetic acid in the color of about 3-4mg/L. If you are not sure about the concentration of peracetic acid in the solution being tested, dilute it.
