4-20mA Low/high Total Chlorine Sensor in Pool Water

Chlorine is a common disinfectant used to kill bacteria, viruses and other microorganisms in water. Monitoring the total chlorine level can ensure that the chlorine concentration in the water is within the safe range to effectively disinfect the water source. Chlorine can react with organic matter to produce carcinogens such as chloroform. Monitoring total chlorine levels can help identify excessive chlorine concentrations in water and avoid potential health risks. Chlorine can also react with other chemicals in the water to form harmful byproducts, and monitoring with a Total Chlorine Sensor can help assess the overall safety of water quality. Especially in swimming pools, chlorine is usually used to disinfect the water quality. On the one hand, it is necessary to ensure that the concentration of chlorine in the swimming pool is high enough to effectively disinfect. On the other hand, if the concentration of chlorine is too high, it will cause harm to the human body. If the total chlorine value is too low, it will cause water quality problems and cannot effectively kill bacteria and microorganisms. Therefore, it is very necessary to continuously monitor the total chlorine value of swimming pool water in real time to keep it within a certain range. Generally speaking, the total chlorine in swimming pool water ranges between 1-3ppm. Daruifuno's CP4 total Chlorine Sensor is designed for monitoring the total chlorine value of various types of water. It is connected with the controller to realize real-time continuous monitoring of the total chlorine value of water quality.

Features
The total chlorine sensor adopts the membrane-covered amperoscopic three-electrode system, with stable measurement and real-time response
Compact and lightweight, can be directly immersed in the flow cell
No need to consume reagents, no chemicals, convenient and simple
The total chlorine sensor has a long service life and low maintenance, and the cost of measurement is significantly lower than that of colorimetric measurement systems

Introduction to the principle of current method
The double electrodes immersed in the electrolyte are in contact with the liquid through the membrane. The dual electrodes are a platinum working electrode and a silver-coated counter or reference electrode. Chlorine compounds in the medium diffuse through the membrane. A constant polarization voltage between the two electrodes triggers an electrochemical reaction of the chlorine compound on the working electrode. The current is proportional to the total chlorine concentration over the sensor's operating range and is virtually independent of pH.

The total chlorine sensor, like the residual chlorine sensor, is widely used in various water treatments such as drinking water, process water, and swimming pool water.
