Product Background: Free chlorine (total chlorine) includes free chlorine and combined chlorine where the free chlorine exists as hypochlorous acid ,hypochlorite ion and simple substance chlorine and combined chlorine as chloramine and organic chloramine . Usually due to chlorination, there exists surplus chlorine in water , which not only affects the taste and odor of the water, undermine its quality , but also may react with some organic matters in the water, generating a series of chlorinated hydrocarbons, such as trichloromethane-bromoform, bromodichloromethane ,dichlorodibromomethane, which have teratogenic ,carcinogenic and mutagenic effects. In addition, surplus chlorine may generate chlorine gas, another toxic matter, which, when in excessive concentration , may cause damages to skin , mucosa,respiratory passage and other human organs, or even death. Hence, developing a new free chlorine testing reagent enabling fast and simplified determination is of great importance for water quality testing and assessment. The researchers of Ningbo Thaile Chemical Technology Co., Ltd have after years of in-depth study , successfully developed a new free chlorine test reagent , under the brand of "Thaile". The invention of this reagent can achieve better and reliable results with greatly simplified operation and lowered testing costs.
Product Theory: Use a specific high-sensitivity reagents, it can generate chemical reaction with chlorine and show color.
Product Use: Quick test free chlorine in water. Usually it used in on-site rapid testing of living water, aquaculture, environmental protection, industrial water etc.
Product Features: Accurate, easy to handle, inexpensive, easy to carry.
Method of Using:
1.Drip 1-2 drops of the reagent into 15ml of the solution being tested (which shall be colorless) and shake well. Read the free chlorine value according to the color change of the solution, against the color chart (the value of free chlorine can be determined immediately after adding the reagent and allow 10 minutes dwelling time for total chlorine).
2.When using this reagent, the color change only occurs when the solution being tested is of pH≤7, if pH>7, please add a few more drops.
Cautions:
1.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.
2.Try to compare the colors in bright light.
3.This product is slightly irritating and aggressive, avoid inhaling. In case of body contacts, rinse with water.
4. After use, please tighten the cap to avoid ineffectiveness.
