CUS4000 Modbus Online Turbidity Sensor Online Turbidity Meter for Sewage Plant Chemical Food Industries 0.01-120000mg/l
Product Spotlights
1.Core Functions:
(1)Multi-Parameter Compatibility: compatible with common electrodes such as pH, conductivity, ORP, residual chlorine, turbidity, and dissolved oxygen, enabling one device for multiple uses.
(2)Intelligent Range Selection :The device automatically matches and switches to the optimal measurement range based on real-time water quality conditions, without manual intervention. This offers two major advantages:
Enhanced Accuracy: Prevents measurement errors caused by improper manual range selection.
Simplified Operation: Significantly reduces operational complexity and improves detection efficiency.
(3)Data Integration & Communication:
Real-time remote monitoring of water quality data.
Automatic recording and storage of data.
Provides a complete data chain for subsequent water quality analysis, process optimization, and data traceability.
Interface: Supports RS485 digital interface.
Protocol: Uses the industrial standard MODBUS-RTU communication protocol.
Capabilities: Can be easily connected to computers, PLCs, or industrial automation control systems to achieve:
2.Application Value: Widely applicable in scenarios requiring collaborative, precise, and continuous monitoring of multiple key water quality physicochemical indicators, such as wastewater treatment, industrial process control, aquaculture, and environmental monitoring.
