Functional features:

• Based on electrochemical work, the platform is fully automated for analysis, automatic cleaning, and the cycle can be set arbitrarily;
• Using graphite electrodes instead of mercury electrodes is safe, reliable, and pollution-free;
• Modular design, easy maintenance, and expandable range;
• Fault alarm, error alarm, automatic power-off protection design, automatic restoration of working status upon incoming call;
• Adopting industrial touch screen operation and display, menu based operation interface;
• Adopting high-quality industrial PLC to reduce system failure rate, with strong anti-interference and lightning resistance capabilities;
• Supports 4-20mA, RS232/485 data transmission protocols, and MODBUS/TCP communication methods;
