Expert in Water Quality Measurement and Water Treatment Project Since 2007
Product Overview
1) Product overview
Product Features
- The BOQU YLG-2058 Residual Chlorine Meter (marketed as a Hach-compatible chlorine analyzer) is an industrial online water-quality analyzer for continuous monitoring of residual chlorine, pH and temperature. It consists of a secondary instrument, sensor and an acrylic flow cell and is designed for fixed (wall or panel) installation for long-term, automated measurements.

Product Advantages
- Simultaneous multi-parameter measurement: residual chlorine, pH and temperature displayed on one screen.
Application Scenarios
- High-resolution ranges: residual chlorine 0–20.00 mg/L (0.01 mg/L), HOCl 0–10.00 mg/L, pH 0–14.00 (0.01), temperature 0–99.9 °C (0.1 °C).
- Good accuracy: residual chlorine ±2% or ±0.035 mg/L (larger), pH ±0.05, temperature ±0.5 °C (0–60 °C).
- Intelligent operation: English display and menu, AD conversion with microcontroller processing, automatic temperature compensation, and self-checking.
- Outputs and alarms: isolated 4–20 mA output (load
- Data logging and protection: one-month data storage at 1 point/5 minutes and IP65 protection rating. Power: AC220V standard (DC24V optional).
3) Product value
- Enables reliable, continuous online control of disinfection and water quality, improving safety and regulatory compliance.
- Reduces manual sampling and lab testing costs through automated real-time measurement and alarmed thresholds.
- Provides actionable data for process control, allowing timely adjustments to dosing and treatment and minimizing over/under-chlorination.
- Robust design and isolated outputs support long-distance signal transmission and integration with plant control systems (SCADA/DCS).
4) Product advantages
- All-in-one multi-parameter monitoring with single-screen readout simplifies operation and reduces equipment footprint.
- High immunity to interference via optoelectronic isolation for stable long-term signals.
- User-friendly English menu and prompts make setup and maintenance faster and less error-prone.
- Flexible output configuration (dual current outputs optional) and adjustable alarm settings fit diverse control schemes.
- Industrial build with IP65 protection and automatic temperature compensation enhances durability and measurement accuracy in field conditions.
5) Application scenarios
- Continuous monitoring of treated and process water in municipal water plants and wastewater/drainage systems.
- Disinfection and residual chlorine control in power plants and boiler feedwater systems.
- Water quality monitoring in hospitals, laboratories and healthcare facilities.
- Industrial process water and effluent monitoring where residual chlorine and pH control are critical (chemical, food, beverage, and other manufacturing).
- Integration into plant automation/SCADA systems for remote monitoring and alarm management.
