Chlorine sensor

The SMART ABFC chlorine sensor is a non-reagent type sensor designed to measure the concentration of chlorine in sample water. This sensor is capable of detecting various forms of chlorine, including chlorine gas (Cl2), hypochlorous acid (HClO), and hypochlorite ion (ClO-). To determine the chlorine concentration in the sample water, the SMART ABFC measures the voltage corresponding to the diffusion current between the indicator and counter electrodes. Additionally, the sensor applies temperature compensation to the diffusion current to ensure accurate and reliable measurements.

In summary, the SMART ABFC chlorine sensor is a powerful tool that enables precise and efficient measurement of chlorine concentration in various forms in sample water.
