The CLG-2096Pro/P online residual chlorine automatic analyzer is a newly developed intelligent online analog instrument independently researched and manufactured by Boqu Instrument Company. It employs a matched analog residual chlorine electrode to accurately measure and display free chlorine (including hypochlorous acid and its derivatives), chlorine dioxide, and ozone present in chlorine-containing solutions. The instrument communicates with external devices such as PLCs via RS485 using the Modbus RTU protocol, offering advantages such as fast communication speed, accurate data transmission, comprehensive functionality, stable performance, user-friendly operation, low power consumption, and high levels of safety and reliability.
Features:
1. With a high accuracy of up to 0.2%.
2. It provides two selectable output options: 4-20 mA and RS-485.
3. Two-way relay offers three distinct functions, making it convenient for system integration.
4. Designed with an integrated waterway and quick-connect fittings, it ensures easy and efficient installation.
5. The system is capable of measuring three parameters—residual chlorine, chlorine dioxide, and ozone—and allows users to switch between measurement parameters as needed.
Applications:
It can be widely applied in waterworks, food processing, medical and healthcare, aquaculture, and sewage treatment for the continuous monitoring of residual chlorine in solutions.
