Introduction
A residual chlorine meter is a device used to measure the concentration of residual chlorine in water or wastewater. Residual chlorine refers to the amount of chlorine remaining in the water after chlorination, which is important to ensure that the water is safe for consumption or use.
Residual chlorine meters use various methods for measurement, including amperometric titration, colorimetry, and electrochemical sensors. These methods offer different advantages and are suitable for different applications, but all provide accurate and reliable measurements of residual chlorine concentration.
In addition to measuring residual chlorine, some advanced models of residual chlorine meters also include features such as automatic temperature compensation, automatic calibration, and data logging capabilities. These features help to improve the accuracy and reliability of the measurements, as well as provide a convenient and user-friendly experience for the operator.
The SIN-TRC400 residual chlorine meters are commonly used in water treatment plants, swimming pools, and other applications where residual chlorine levels need to be monitored for safety and regulatory compliance. A residual chlorine meter can help ensure that the water being used is safe and free from harmful contaminants, providing peace of mind for both operators and users.
