Anti-Corrosive Wastewater Conductivity Electrode Applications

● High-Salinity Wastewater & Seawater Desalination: Unlike standard 2-pole sensors that suffer from polarization at high concentrations, the LT5700I’s 4-pole graphite design effortlessly measures extreme ranges up to 0-500mS/cm. This makes it uniquely suited for marine environments, brine monitoring, and desalination plants where massive conductivity fluctuations occur.
● Harsh Chemical & Acid-Base Processing: Relying on a rugged graphite measuring tip and a specialized POM housing, this sensor provides superior resistance to chemical corrosion. It is the ideal solution for chemical plants manufacturing strong acid-base salts or facilities dealing with aggressive, corrosive media where traditional stainless steel probes would rapidly degrade.
● Automated Industrial Effluent Monitoring: Because the traditional transmitter is integrated directly into the probe’s microprocessor with an RS485 ModBus RTU output, it is uniquely designed for modern industrial PLC integration. Factory operators use it for plug-and-play continuous monitoring in complex industrial wastewater networks, saving significant installation costs and equipment space.
