The K-7404 ozone test kit is a quick, easy, and reliable method to measure dissolved ozone levels in water. This is a manual coloremetric test kit that will measure ozone in water directly up to 3.0 ppm.
The K-7404 Dissolved Ozone Test Kit allows you to test for dissolved ozone levels in the range of 0.05 ppm – 3.0 ppm. Included in the kit are 30 test ampoules, which are used up and are replaceable. There is also a cylinder of activator solution included, which causes a chemical reaction during the test. This solution is also used up and can be replaced. The permanent parts of the kit are the box itself, the 25 mL test cup, and the two-color comparators. The lower level color comparator has a range of 0.05 ppm dissolved ozone and goes up to 0.6 ppm dissolved ozone. The higher range color comparator starts where the other one left off, going from 0.6 ppm to 3.0 ppm dissolved ozone.
To take the test, first make sure all the items you need for the test are laid out. This is important because once you take your sample of dissolved ozone, you need to proceed through the test steps quickly to ensure the dissolved ozone doesn’t break down. If you take too long between taking the sample and testing the level of dissolved ozone, you will get an inaccurate reading showing lower levels of dissolved ozone than what truly exists.
Add five drops of activator solution to the empty sample cup. Then add 25 mL of dissolved ozone to the sample cup. Quickly place the tip of the ampoule in the cup, swirl it several times, and snap off the end of the vial at the bottom of the cup. The vial will instantly fill with the sample, because the vial is vacuum sealed. Move the vial back and forth several times so the bubble moves up and down the tube, thoroughly mixing the sample. Wait 1 minute. Compare the color of the test ampoule to the varying levels of pink-colored tubes in the color comparators. The darker the pink, the higher the levels of dissolved ozone.
