WQA-5600C Online Multi Parameter Water Quality Analyzer RS485 Modbus 316L Stainless Cell

WQA-5600C Online Multi Parameter Water Quality Analyzer

The WQA-5600C is a continuous online multi parameter water quality analyzer for plant rooms, pump stations and treatment lines that run around the clock. This upgraded model answers the three issues operators reported most often with the previous series: readings that drifted between calibrations, wet cells that corroded in chlorinated water, and controllers that were difficult to integrate with existing SCADA systems.

Higher Accuracy Than Previous Generation

• pH accuracy of plus or minus 0.01 pH with a ceramic double junction reference that holds potential stable in chloride-rich samples.
• Conductivity accuracy of plus or minus 0.5% FS with automatic temperature compensation across the full working range.
• Long term drift reduced from 0.5% to below 0.2% per 24 hours, extending the practical calibration interval from two weeks to about four weeks.
• Residual chlorine and turbidity channels calibrated against certified standards, with a two-point calibration record stored in the controller.

Improved Instrument Performance

• Continuous operation with a 5 second refresh interval, so control actions respond to real process changes rather than averaged data.
• RS485 Modbus RTU plus 4-20 mA and two relay outputs, allowing direct integration with PLC, SCADA and dosing control without extra transmitters.
• Watchdog and power-loss recovery functions restart the analyzer automatically after an interruption, with readings resuming without operator action.
• Remote firmware update and parameter configuration over Modbus, so a site visit is not required for routine setting changes.
• 30 day rolling data log with SD card export for reporting and trend analysis.

Upgraded Materials and Construction

• 316L stainless steel flow cell replaces the previous engineering plastic cell, resisting chlorinated, saline and mildly acidic process water.
• PVDF cell body and PTFE sample tubing resist UV degradation and creep at elevated sample temperatures up to 80 degrees Celsius.
• Ceramic double junction electrodes extend service life in samples containing sulphide, ammonia or suspended solids.
• IP66 control enclosure with a sealed membrane keypad keeps moisture and dust out of the electronics compartment.
