RS485/ 4-20 mA Total Hardness Sensor for Water Quality Monitoring

ZONEWU RS485 Water Quality Total Hardness Sensor:
Water quality total hardness sensor equipped with RS485 (Modbus-RTU) communication protocol, featuring high-precision detection of calcium and magnesium ion content, anti-fouling and corrosion-resistant probe, automatic temperature calibration, and plug-and-play compatibility with industrial control systems, IoT platforms and data acquisition terminals for stable and high-speed wired data transmission.

RS485 Total Hardness Sensor: Key Applications & Use Cases
1. Municipal Drinking Water Distribution & Terminal Monitoring
Deployed at urban water supply networks, residential quarter water supply stations, and commercial building water intake points, it conducts 24/7 online monitoring of total hardness fluctuations in tap water. Through RS485 data transmission, it timely alerts the risks of excessive water hardness and pipeline scaling, ensures the compliance of domestic water quality with national standards, and assists water supply departments in optimizing water treatment processes.
2. Industrial Circulating Water System Management
Suitable for industrial scenarios such as thermal power, chemical engineering, and HVAC systems, it is installed in circulating cooling water pipelines, heat exchangers, and boiler water supply systems. It accurately captures abnormal changes in water total hardness, provides data support for scale inhibitor dosing and water replacement scheduling, prevents equipment scaling and heat exchange efficiency reduction, and reduces industrial water consumption and maintenance costs.
3. Food & Beverage Processing Quality Assurance
Applied in beverage factories, dairy processing plants, and brewing enterprises, it is deployed at raw water intake, production process water, and finished product water detection nodes. It strictly controls the total hardness of production water to meet industry-specific process standards, ensures the taste stability and quality consistency of food and beverage products, and helps enterprises meet food safety regulatory requirements.
4. Aquaculture & Aquatic Product Breeding Monitoring
Designed for freshwater aquaculture ponds, recirculating aquaculture systems (RAS), and ornamental fish breeding bases, it is resistant to high humidity and organic matter-rich water environments. It real-time monitors water total hardness and cooperates with pH and temperature data to help breeders scientifically adjust water quality parameters, avoid fish and shrimp stress reactions caused by hardness mutations, and improve the survival rate of aquaculture products.
