High-Precision Water Quality Tester – PH, Chlorine, DO Sensor with 4-20mA/RS485 Output

Industrial-Grade Durability
Constructed with corrosion-resistant stainless steel and high-sealing IP68 casing for long-term submersion in harsh environments, ensuring accurate readings in wastewater, aquaculture, or industrial monitoring.
Triple-Parameter Detection
Simultaneously measures pH, chlorine (Cl2), and dissolved oxygen (DO) with ±0.1pH/0.1mg/L precision, featuring automatic temperature compensation for reliable data in fluctuating conditions.
Universal Signal Output
Equipped with 4-20mA analog and RS485 digital outputs (Modbus RTU protocol), compatible with PLCs, SCADA systems, and IoT platforms for seamless integration into smart water management networks.
Lab-Calibrated Accuracy
Pre-calibrated with NIST-traceable buffers and includes replaceable sensor caps for easy maintenance, minimizing downtime in municipal plants, hydroponics, or pool water testing.
Zero-Power Design
Passive sensing technology eliminates external power needs for probes, reducing operational costs in remote monitoring setups like rivers or reservoirs.
Bulk Order Advantage
Direct factory pricing for large-quantity purchases, with ISO-certified production ensuring batch consistency for commercial buyers and OEM partners.
Typical Applications
Drinking water facilities, aquaculture oxygenation control, chemical processing plants, environmental research stations, and swimming pool sanitation systems.
