The Multi-Parameter Water Quality Online Analyzer is a water quality monitoring device that can be widely used for online water quality monitoring in urban or rural water treatment plants, water supply networks, secondary water supply systems, end-user points, indoor swimming pools, large-scale water purification equipment, and drinking water systems. It is an indispensable online analytical device for water plant production process control, water resources management, and health supervision.
The multi-parameter water quality analyzer monitors parameters including pH, turbidity, residual chlorine (chlorine dioxide, ozone), temperature, conductivity (TDS, salinity), and ORP. Additional or reduced monitoring parameters can be customized according to customer requirements.
• Compact modular design, capable of simultaneously monitoring up to 6 parameters.
• Selectable measurement parameters with high accuracy and good repeatability.
• Sensors can be freely combined, with simple installation and easy maintenance.
• No reagents required, no reagent consumption.
• No secondary pollution, no waste liquid.
• Temperature compensation for electrodes within a certain range.
• Multiple output options available.
