1. Why need a testThe chlorine dioxide disinfectant is orange-yellow at high concentration, and pale yellow at low concentration. It has a special pungent odor of nitrogen and ozone. Chlorine dioxide disinfectant is an internationally recognized safe and non-toxic disinfectant.To achieve a good disinfectant effect it’s necessary to ensure that the active ingredients are within a certain range. Using the method of Quick Test Strip, the content of the disinfectant can be quickly and semi-quantitatively determined, so that the concentration of the disinfectant can be changed or adjusted.

2. How do a test

2.1 Take a piece of card and tear off the cover film

2.2 Insert the quick test strip into the disinfectant for about 1 second then take it out. Next compare it with the colorimetric version to determine the content.

2.3 If the concentration is higher than the color level of 500 mg/L, the disinfectant can be diluted with water and then measured, and then the concentration value obtained from the comparison multiplied by the dilution factor is the concentration of the disinfectant.

3. NotesThe quick test strip also works on chlorine preparation disinfectant. If it's not chlorine dioxide disinfectant, the test result is the content of available chlorine.

4. Product packaging: 50 tablets per pack

5. The test strips are stored in a cool and dry place, and the validity period is 24 months.

1. 检测意义:二氧化氯消毒液高浓度时为橙黄色,低浓度时呈现淡黄色。具有氮和臭氧的特殊刺激性嗅味。二氧化氯消毒剂是国际上公认的安全、无毒的消毒剂。要达到良好的消毒效果,必须保证有效成分在一定的区间。采用速测卡试纸方法,可以对消毒液含量快速半定量,以便更换或对消毒液的浓度进行调整。

2. 使用方法

2.1 取一片卡片,撕去上盖膜;

2.2 将速测卡插入消毒液中约1秒后取出,与比色版对比确定含量。

2.3 若浓度高于色阶500mg/L时,可将消毒液用水稀释后再测,比对出的浓度值乘以稀释倍数即为消毒液的浓度。

3.注释

3.1 速测卡对氯制剂消毒液也有测试效果,如果不是二氧化氯消毒液,测试出的结果为有效氯的含量。

3.2 二氧化氯与其他常用消毒剂的比较
