Product Overview:

The HACH 9184sc residual chlorine online detector uses selective electrodes for residual chlorine detection, featuring plug-and-play functionality, a wide range, and low detection limits; This residual chlorine online detector has built-in pH/temperature automatic compensation, making it especially suitable for residual chlorine detection in membrane treatment processes such as reverse osmosis, ensuring more accurate readings.

Working Principle:

The principle of the 9184SC residual chlorine online detector is: the electrolyte and the permeation membrane separate the electrolytic cell from the water sample, allowing the permeation membrane to selectively allow ClO- penetration; There is a fixed potential difference between the two electrodes, and the generated current intensity can be converted into residual chlorine concentration. Through the following reactions, the system can accurately measure residual chlorine:

At the cathode: ClO- + 2H+ + 2e- →Cl- + H2O

On the anode: Cl- + Ag→ AgCl + e-

Due to the fixed conversion relationship between HOCl, ClO-, and residual chlorine under specific temperature and pH conditions, the 9184SC residual chlorine detector can accurately detect residual chlorine using the electrode method.

Application Industries:

The 9184SC residual chlorine online detector is suitable for detecting hypochlorous acid (HOCL)/residual chlorine in drinking water and industrial water disinfection processes, especially for detecting residual chlorine in influent water from membrane treatment processes such as reverse osmosis.
