Functional features:

• The sequential injection platform is fully automated for analysis, automatic cleaning, and the cycle can be set arbitrarily;
• Strong masking ability for chloride ions, capable of analyzing water samples with chloride ion concentrations below 20000mg/L;
• High temperature and high pressure digestion system accelerates the reaction process and shortens the detection time;
• 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;
• Supports 4-20mA, RS232/485 data transmission protocols, and MODBUS/TCP communication methods;
