Product Description Water Quality Analyzer Electrodes: Technical Overview1. pH ElectrodesCore Structure: Composed of a low-impedance glass membrane (e.g., GFT EST-701Y) and an Ag/AgCl reference system with gel electrolyte, ensuring stable potential and anti-pollution performanceFeatures:Wide measurement range (0-14 pH) with linear response.Suitable for harsh environments, including wastewater and high-temperature applications (e.g., -5°C to 135°C) .Requires regular calibration with standard buffer solutions (e.g., pH 4.01, 7.00) for accuracy 2. Dissolved Oxygen (DO) ElectrodesDesign: Utilizes Clark-type membrane technology or optical sensors (e.g., SWAN A-87 series), often integrated with automatic temperature compensation (ATC) for real-time monitoring Applications:Ideal for aquaculture, environmental monitoring, and industrial water systems.Maintenance involves periodic membrane replacement and calibration with zero-oxygen solutions (e.g., sodium sulfite)3. Conductivity ElectrodesConfiguration: Features multi-ring (e.g., 4-ring) or graphite sensors with epoxy resin bodies for wide-range measurement (0-2000 μS/cm to 20,000 μS/cm) Key Parameters:Temperature compensation (NTC10K/PT1000) ensures accuracy across varying conditions.Used in pure water systems, boiler water, and chemical processes 4. Ion-Selective Electrodes (ISE)Function: Measures specific ions using ion-sensitive membranes. Examples include calcium hardness electrodes (Bsens740) for industrial water monitoring Advantages:Direct measurement without reagents; minimal maintenance.Calibration requires standard ion solutions (e.g., 0.1M HCl for electrode reactivation)5. ORP (Oxidation-Reduction Potential) ElectrodesStructure: Platinum or gold sensing elements with a double-junction reference system to prevent contamination Usage: Critical in disinfection (e.g., chlorine monitoring) and redox reaction analysis.6. Multi-Parameter ElectrodesIntegration: Combines pH, DO, conductivity, and ion sensors (e.g., ThermoFisher Eutech PCD650) for comprehensive analysis Features:Waterproof housing (IP65/IP67) for field use.Supports RS485/Modbus communication for data logging and remote control .Maintenance Guidelines:Calibration: Use certified standards (e.g., NIST-traceable solutions) and follow manufacturer protocols .Cleaning: Remove contaminants with deionized water or specific solvents (e.g., 4% HF for glass membrane scaling) Storage: Keep electrodes hydrated (e.g., in 3M KCl for pH electrodes) to prolong lifespan For detailed specifications, refer to technical manuals from brands like SWAN 6, GreenPrima , or HANNA
