Introduction: Importance of Monitoring Residual Chlorine in Water

Residual chlorine is a commonly used water disinfectant that effectively kills bacteria, viruses, and other microorganisms in water, preventing water source pollution and the spread of waterborne diseases. By monitoring residual chlorine concentration, it ensures that the disinfection process meets health standards, safeguarding the safety and health of water supply systems. According to the new regulation GB5749-2022 Hygienic Standards for Drinking Water introduced in 2022, the residual chlorine content in drinking water should be ≤2 mg/L and ≥0.3 mg/L at the water treatment plant outlet, and ≤2 mg/L and ≥0.05 mg/L at the end of the distribution network (i.e., at the consumer's tap).

INSTRUMENT OVERVIEW

The ATE2130-YL Online Residual Chlorine Sensor, based on the principle of constant voltage, utilizes a specific electrode system, stable voltage application, electrochemical reactions, and rapid feedback mechanisms to achieve accurate and stable measurement of residual chlorine in water samples. This method offers advantages such as low maintenance, long electrode lifespan, and high reliability. It has been widely applied in drinking water treatment and swimming pool water monitoring. The electrode-based online residual chlorine analyzer eliminates the drawbacks of traditional chemical methods, such as inconvenient installation and cumbersome reagent addition. It features reagent-free operation, simplified maintenance, and no secondary pollution.

WORKING PRINCIPLE

The constant voltage method online residual chlorine sensor operates on the principle of maintaining a stable potential between the measuring and reference electrodes. Different components generate varying current intensities at this potential. Typically, the system consists of two platinum electrodes and a reference electrode, forming a microcurrent measurement system. Chlorine molecules or hypochlorite ions are consumed at the electrode surface, and the resulting current intensity is proportional to the residual chlorine concentration in water.
