Platinum Electrode Residual Chlorine Sensor – Membrane-Free, Reagent-Free, RS485 Modbus For Drinking Water
1. Product Overview
The uncoated digital disinfectant sensor has three electrode, it can measure constant potential and current. Our company has intellectual property rights of this product.
The sensor can be used to measure the concentration of disinfectants such as free chlorine, chlorine dioxide (high purity), and ozone. It is mainly used in application scenarios such as tap water, pipe networks, secondary water supply, water ends, and swimming pools. The electrode has a built-in ARM processor and high-efficiency filtering algorithm, which can effectively avoid the interference of noise. It has an RS-485 interface, which is convenient for access to computers and network monitoring systems.
2.Measurement Principle
The uncoated digital disinfectant sensor consists of two platinum electrodes and a silver chloride electrode to form a three-electrode measurement system. The electrode has a built-in high-precision potentiostat, which can keep the working electrode potential stable. Disinfectant components such as hypochlorous acid undergo a redox reaction at the working electrode, and the current generated follows Faraday's law, so we can measure the concentration of the disinfectant.
3. Product Features
1.We use electronic and chemical sensors, there is no reagent consumption and pollutant emissions;
2.It is designed without film. So there is no need to replace the membrane head and adding electrolyte;
3.We designed three electrodes, there are zero point stability and high sensitivity;
4.The built-in high-precision sampling circuit makes the sensor linearity good;
5.When the pH does not change much, it can be accurately compared with the DPD measurement method.
