Residual Chlorine Meter Residual Chlorine Analyzer Quality Assurance
Product Overview
- CLG-2059S/P Residual Chlorine Meter / Residual Chlorine Analyzer by BOQU is an online, integrated instrument for continuous residual chlorine and temperature monitoring. It combines a digital residual-chlorine sensor, flow cell, piping and valves into a single controller-based unit with onboard database and calibration functions for centralized observation and management.
Product Features
- Measured parameters: residual chlorine and temperature. Range: 0–20 mg/L (pH 5.5–10.5) and 0–60°C; resolution 0.01 mg/L and 0.1°C; residual chlorine accuracy ±2% FS; temperature ±0.5°C.
- Outputs & communications: 4–20 mA current output, RS485 Modbus RTU, two relays (5 A @ 250 V AC / 5 A @ 30 V DC). Optional wireless for mobile app and web.
- Mechanical/electrical: IP65 protection, wide AC input 85–265 VAC, flow 15–30 L/H, dimensions 600 × 400 × 230 mm, inlet 6 mm / outlet 10 mm.
- Built-in functions: precision digital sensor, bubble rejection, classic flow-cell design, automatic drain, data saving and power-off protection, anti-electromagnetic interference and surge protection. Low manual maintenance; plug-and-use installation.
Product Value
- Provides reliable, continuous online chlorine monitoring to protect public health and product quality.
- Reduces manual sampling and laboratory testing, speeds response to deviations, and supports regulatory compliance and quality assurance through logged data and calibration records.
- Enables centralized and remote oversight (with optional wireless), improving process control and operational efficiency across water treatment and production systems.
Product Advantages
- Integrated design: sensor, flow cell and control in one compact, plug-and-use unit simplifies installation and maintenance.
- High measurement stability and accuracy from a precision digital sensor plus bubble-rejection and automatic drain features.
- Robust operation: wide power range, surge/EMI protection, power-off data protection and IP65 enclosure for harsh environments.
- Flexible connectivity and control: analog output, Modbus RTU, relay alarms, and optional wireless access for SCADA/remote monitoring.
- Backed by BOQU’s technical team and nationwide distribution/support.
Application Scenarios
- Continuous monitoring of clean and potable water systems.
- Swimming pool chlorine control.
- Food & beverage water quality monitoring.
- Process and treated process water monitoring in industrial plants.
- Pipe networks, secondary water supply, and other distribution systems requiring residual chlorine assurance.
