Description

The JDZMAS Multi-Parameter Water Quality Monitoring System is a modular flow-through cell and integrated controller-based online monitoring solution capable of connecting and collecting data from over a dozen digital and analog water quality sensors.

• High Flexibility: Modular structure adapts to diverse process installation requirements. Flexible mounting ensures high-precision measurement results.

• High Integration: Integrates multiple parameters—turbidity, residual chlorine, pH, conductivity, etc.—into a single flow cell for simplified maintenance and installation in drinking water monitoring systems.

• Effortless Maintenance: Optional cleaning and sample injection units enable automated cleaning.

• Next-Generation Controller: Android-based controller delivers a smoother, more aesthetically pleasing interface. Supports software upgrades, all digital/analog sensors, and wireless 4G communication. Features massive data storage capacity and analysis capabilities, enabling data viewing and analysis without additional computers.

Advantage

◆ Multi-channel controllers support all digital and analog sensors with flexible configuration options. Featuring a layered software architecture, they automatically pair and identify probes for plug-and-measure functionality.

◆ Equipped with a 7/10-inch TFT touchscreen and large-capacity data storage supporting up to 16GB.

◆ Runs on Linux OS with a newly designed graphical interface software. Displays historical curves for any parameter. User-friendly software design supports multiple protocol formats.

◆ Integrated remote transmission module. Standard 4G full-network wireless transmission (Bluetooth, Wi-Fi, NB-IoT optional). Supports Ethernet transmission and RS485 Modbus RTU.
