Residual Chlorine Analyzer - for Wholesale - BOQU
Product Overview
The CLR-2059G (also referenced as CL-2059G) Residual Chlorine Analyzer by BOQU is a precision online instrument for continuous measurement of free/residual chlorine concentration. It supports a wide measuring range (0.005–20.00 ppm) with 0.001 mg/L resolution and is designed for industrial/municipal water monitoring and wholesale/system-integration applications.
Product Features
- Measurement range: 0.005–0.500 / 2.00 / 5.00 / 10.00 / 20.00 ppm (mg/L) with 0.001 mg/L resolution and ±2% F.S. accuracy.
- Flow-cell requirement: 15–30 L/h.
- Automatic temperature compensation and stable zero/no-drift performance for reliable real-time readings.
- Diaphragm-covered residual chlorine electrode for reduced flow dependence and cross-sensitivity.
- Outputs and communication: standard RS485 Modbus, 4–20 mA, and high/low relay control.
- Power: 220 VAC, 50/60 Hz. Size: 300 × 250 × 165 mm.
Product Value
The analyzer delivers accurate, continuous chlorine monitoring to protect public health, ensure regulatory compliance, and optimize disinfection dosing. Real-time data and multi-output interfaces enable immediate control actions, alarm triggering, and integration into SCADA/DCS for reduced chemical waste, lower operating costs, and improved process safety.
Product Advantages
- High precision and reliable, drift-free readings for long-term monitoring.
- Robust sensor design (diaphragm-covered electrode) with good resistance to mechanical stress and chemical corrosion.
- Automatic temperature compensation minimizes measurement errors related to temperature change.
- Flexible integration with standard industrial interfaces (RS485 Modbus, 4–20 mA, relay).
- Manufactured with advanced production equipment and backed by BOQU’s R&D, production, and service capabilities for durability and cost-effectiveness.
Application Scenarios
Suitable for continuous residual chlorine monitoring in: swimming pools, tap/drinking water systems, medical/industrial wastewater, industrial circulating water, CIP (clean-in-place) systems, sewage treatment plants, and other water treatment or process water applications where reliable chlorine control and alarms are required.
