Brief: Discover the CST520 Multi Electrode Array Electrochemical Mapper, designed for precise pitting corrosion potential measurement. This advanced tool maps galvanic current and OCP distribution, ideal for studying non-uniform corrosion under coatings, deposits, and anti-rust oils. Perfect for lab research and corrosion mechanism analysis.
Related Product Features:
  • High-resolution AD converters and zero resistance ammeter techniques for accurate measurements.
  • Maps galvanic current and OCP distribution on arrayed multi-electrodes.
  • Compatible with CS potentiostat for impedance distribution mapping.
  • Cyclic scanning of potential and current distribution for local corrosion analysis.
  • Precisely measures electrode potential and short-circuit current of any single electrode.
  • Supports up to 100-channel array electrode switching with a switch rate of 100Hz.
  • Includes techniques like OCP, Tafel, LPR, EIS, M-S curve, and ECN for comprehensive corrosion evaluation.
  • Real-time potential/current distribution display with data importable to Origin for 3D graphs.
Faqs:
  • What is the primary application of the CST520 Multi-electrode Array Electrochemical Mapper?
    It is used for studying local corrosion distribution characteristics of metal surfaces and the mechanism of local corrosion development, suitable for lab research and non-uniform corrosion behavior analysis.
  • How does the CST520 measure corrosion potential and current?
    The CST520 uses high-resolution AD converters and zero resistance ammeter techniques to map galvanic current and OCP distribution, enabling precise measurement of electrode potential and short-circuit current.
  • What techniques are supported by the CST520 for corrosion evaluation?
    The CST520 supports techniques like open circuit potential (OCP), polarization curve (Tafel), linear polarization (LPR), EIS, M-S curve, and electrochemical noise (ECN) for comprehensive corrosion resistance assessment.
