Product Model :T8000-F
System Description
The T8000-F fluoride online monitoring instrument is a new generation of fully automatic maintenance free online monitoring equipment developed based on Chinese standard methods. After acidification, the fluorinated substance in the solution is uniformly converted into fluoride ions. After adjusting the pH value of the solution, a characteristic colorimetric agent is added for colorimetric determination. This method has wider applicability and accuracy than the ion selective electrode method, and is not affected by the severity of water quality. The standard specification implemented is HJ488-2009, which is also a standard method in China.
Measurement Method
After acidification, adjust the pH value of the solution and add a characteristic colorimetric agent for colorimetric determination.
