CS3601C Conductivity Sensor RS485 EC Probe
The graphite conductivity electrode is a robust and widely used sensor designed for measuring the electrical conductivity of aqueous solutions in demanding industrial, environmental, and process control applications. It offers a cost-effective and durable alternative to traditional platinum electrodes, particularly in media where fouling, abrasion, or chemical attack are concerns.
The electrode typically consists of two precisely spaced graphite elements (cells) encased within a chemically resistant body, such as PPS or epoxy. Graphite's inherent conductivity and porous structure provide a large effective surface area, ensuring stable signal generation. When an alternating current is applied, the ions in the solution complete the circuit between the electrodes; the measured conductance is directly proportional to the ion concentration. A built-in temperature sensor (usually a Pt1000 RTD) is essential for automatic temperature compensation, correcting readings to the standard reference of 25°C.
These electrodes are integral to systems monitoring water purity (e.g., RO permeate, ultrapure water), controlling chemical dosing in wastewater treatment, and managing concentration in industrial processes like cooling towers or food & beverage production. When paired with a high-quality transmitter, the graphite conductivity electrode provides a reliable balance of performance and longevity for challenging on-line monitoring tasks, forming a critical component in modern water quality management. -

T9040 Water Quality Multi-parameter online monitoring system
Water Quality Multi-parameter Online Monitoring System is an integrated, automated platform designed for the continuous, real-time measurement of multiple critical water quality parameters at a single point or across a network. It represents a fundamental shift from manual, laboratory-based sampling to proactive, data-driven water management across drinking water safety, wastewater treatment, environmental protection, and industrial process control.
The core of the system is a robust sensor array or a centralized analyzer that hosts various detection modules. Key measured parameters typically include the fundamental five (pH, Dissolved Oxygen (DO), Conductivity, Turbidity, and Temperature), often extended with Nutrient Sensors (Ammonium, Nitrate, Phosphate), Organic Matter Indicators (UV254, COD, TOC), and Toxic Ion Sensors (e.g., Cyanide, Fluoride). These sensors are housed in durable, submersible probes or flow-through cells, connected to a central data logger/transmitter.
The system's intelligence lies in its automation and connectivity. It performs automatic calibration, cleaning, and data validation, ensuring long-term reliability with minimal maintenance. Data is transmitted in real-time via industrial protocols (4-20mA, Modbus, Ethernet) to central Supervisory Control and Data Acquisition (SCADA) systems or cloud platforms. This enables instant alarm triggering for parameter exceedances, trend analysis for predictive maintenance, and seamless integration with process control loops for automated chemical dosing or aeration control.
By providing a comprehensive, real-time water quality profile, these systems are indispensable for ensuring regulatory compliance, optimizing treatment processes, protecting aquatic ecosystems, and safeguarding public health. They transform raw data into actionable intelligence, forming the backbone of modern smart water networks. -
