The Multi-Parameter Water Quality Online Analyzer is a reliable solution for continuous water quality monitoring across a wide range of applications. It is commonly used in urban and rural water treatment plants, municipal water supply networks, secondary water supply systems, end-user outlets, swimming pools, large-scale purification facilities, and drinking water distribution. By delivering real-time, accurate data, it plays a key role in process control, water resource management, and public health supervision.
This analyzer can measure multiple parameters simultaneously, including pH, turbidity, residual chlorine (chlorine dioxide, ozone), temperature, conductivity (TDS, salinity), and ORP. Monitoring options can be tailored to specific project needs, allowing users to add or remove parameters as required.
• 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 wall-mounted 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.
