CS3501C Conductivity Sensor Analyser
The electrode typically features two graphite elements (cells) with a defined surface area and spacing, housed within a durable, chemically resistant body. When immersed, an alternating current is applied to prevent polarization. The ions in the solution facilitate current flow between the electrodes, generating a signal proportional to the solution's conductivity. A built-in temperature sensor (e.g., Pt1000) is essential for automatic compensation, as conductivity is highly temperature-dependent. Modern versions often incorporate multiple cells (like four-electrode designs) to extend range and minimize fouling errors.
The primary advantage of graphite over platinum is its superior cost-effectiveness and robustness in harsh or fouling-prone environments, such as wastewater, cooling towers, or chemical processes where abrasion or coating is a concern. However, graphite may have limitations in very high-precision or ultra-pure water applications compared to advanced platinum cells. -

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. -
