Its actually quite simple,
Your test strips will have colors on it and beside each color it will prob say 100ppm to 500pm.
When you make your cds solution and its done this is how you test it.
You buy a syringe and take 1ml of your solution and put it in a emplty little glass, then you add 9 ml of distilled water. So that will equal a total of 10ml.
Then take your test strip out and put it in the 10ml glass you just made. It will come up whatever color. If for example the color is black - it will read 500ppm. But because you added 9ml water to your 10ml solution of cds you will times the 500ppm x 10 which means you made a 5000ppm cds solution. If that happens dont worry- just add water to your cds solution until it reads 300ppm on your test strip and then that will mean 3000ppm.
If you make a cds solution and again take 1 ml out of it and put it in a glass and add 9 ml of distilled water and you test it and the color comes out whatever color your test strips shows makes 300ppm. Then you know you made it right.
So simply if you add 1 ml of cds and 9 ml of water and test it - whatever number it comes up (from the color on the test strip) then you just add a zero on the test strip in your mind. so if it reads 100ppm then its a thousandppm, if it reads 200ppm then its 2000ppm, if it reads 300ppm then its 3000 all because yout multiplying whatever number you get by 10 when you test it cause your adding 1ml of cds solution to 9 ml of distilled water equaling 10.
Hope this helps, take care
