Background: As a strong oxidant that can quickly kill bacterium and inactivate viruses, ozone can be uses for water disinfection. For better disinfection effect, it is usually required to control and monitor the ozone concentration in water. However, as only limited amount of ozone can dissolve in water and which is instable, it is difficult to obtain accurate result with samples in a laboratory, the R&D team of Thaile Chemical has successfully developed “Thaile” ozone test kit for quick on-spot testing. The new test kit can greatly simplify the operation and significantly lower the testing cost with reliable testing result.

Principle:Testing based on DPD method of national standard.

Purpose:Quick and accurate test of water Ozone content for monitoring the use status of the ozone generator anytime and anywhere. On-spot quick test in various water consumption field, including industry, agriculture, aquiculture, healthcare, environment and domestic.

Features:

1.Quick and easy:No special training is required, as long as the user follows the instruction. It takes only 5 minutes to finish a test for one water sample.

2.Accurate and reliable:With test results equivalent to what national standard suggests, it is an alternative of the method introduced in the national standard.

3.Highly sensitive:The reagent is highly sensitive to Ozone, with precision as high as 0.05mg/L.

4.Affordable: Cost per test is low.

5.Portable:Compact in size, lightweight, and suitable for on-spot quick test.

Operation:

1.Wash the colorimetric tube twice with water sample. Then, measure and take certain amount of water using the colorimetric tube. Adjust the level to the graduation mark of 15ml using a plastic dropper.

2.Ladle 1 flat ladle(use the colorimetric card to cut the powder so that it levels with the rim of the ladle)of Reagent I and add it into the colorimetric tube, then add 1 flat ladle of Reagent II into the same tube at once. Agitate the solution to make the powder dissove in the solution.

3.Start colorimetric test, after the powdered reagent dissolves, the process should be finished within 5 minutes. Vertically place the colorimetric tube 1cm above the blank area of the colormetric card and visually compare the colors from above. Read the Ozone content of the water sample by finding the color code that appear the same color as that of the liquid in the tube.

Notes:

1.This product has a detectable Ozone content range of 0.05-1.0mg/L. If the Ozone content of the water sample is higher than the upper limite of the detectable range , dilute the water sample before testing.The actual result is obtained by timing the reading with corresponding dilution ratio.

2.If there are agglomerations in the powder, smash them with the ladle before using it. As the reagent is in excessive amount, small amount variation each time after cutting flat the powder will not affect the test result.

3.If the water sample appear turbid, filter the sample, or stand the sample until it is clear, then take sample from the upper part, before testing.

4.The pH of the water sample shall be controlled in the range of 5-8.

5. The existence of other oxidants may interfere with this method.

6.Try to compare the colors in bright light.

7. In case of skin or eye contact of the reagent, just wash it away with water. As reagent Ⅱ is alkalescent, keep it away from body.

8. Tighten the cap after use to avoid lapse.

Liability:The manufacturer and its authorized agents are free from any liabilities due to accidental intake of children and misunderstanding or misuse of the users. If the results of test are dubious, please present the sample to authoritative laboratory for further test.
