Expert in Water Quality Measurement and Water Treatment Project Since 2007
Safe to Use Water Quality Meter for Aquariums
Product Overview
1) Product overview
Product Features
- Model: CLG-2096Pro Online Residual Chlorine Analyzer from Shanghai BOQU Instrument Co., Ltd.
Product Value
- Purpose: Continuous online measurement and display of free chlorine (hypochlorous acid and related salts), chlorine dioxide (ClO2) and dissolved ozone (O3) in chlorine-containing waters.
Product Advantages
- Form factor: Compact ABS enclosure (98.2 × 98.2 × 128.3 mm), IP65 protection, low power consumption (4 W), mains (100–240 VAC) or optional 24 VDC supply.
Application Scenarios
- Interfaces: Two 4–20 mA outputs, RS485 (Modbus RTU) communication and two relay outputs for high/low control.
2) Key product features
- One sensor measures three parameters: free chlorine, ClO2 and dissolved ozone.
- High resolution and range: 0–20.00 mg/L range with 0.01 mg/L resolution.
- Claimed high accuracy and stability: ±0.2% (with stable zero point and low drift).
- Temperature compensation (NTC10k or optional Pt1000) with 0.1°C resolution; operates 0–50°C.
- Diaphragm-covered electrodes to reduce flow dependency and cross-sensitivity.
- Fast, reliable communication via Modbus RTU (RS485) for PLC/SCADA integration.
- Built-in relay alarms and dual current outputs for control and data logging.
3) Product value
- Ensures safe, continuous monitoring of disinfectant levels to protect aquatic life and maintain water quality.
- Enables real-time control and automated responses (via relays/4–20 mA), reducing manual testing and operational risk.
- Facilitates integration into existing control systems for centralized monitoring and record-keeping.
- Low power, compact and weather-protected design makes it suitable for long-term field or facility installation.
- Helps operators meet regulatory and hygiene requirements by providing accurate, continuous residual chlorine data.
4) Product advantages
- Mature manufacturing and quality control from BOQU, with proven after-sales support.
- Multi-parameter capability in a single probe reduces equipment footprint and cost.
- Stable measurements with reduced drift thanks to diaphragm-covered electrodes and temperature compensation.
- Flexible outputs and standard Modbus protocol ensure easy integration with PLCs and building/facility automation.
- Robust, splash-protected housing (IP65) and wide working/storage ranges for reliable performance in varied environments.
5) Application scenarios
- Aquariums and aquaculture: continuous monitoring to keep disinfectant concentrations safe for fish and other organisms.
- Water treatment plants and distribution systems: online residual disinfectant control.
- Swimming pools, spas and recreational water facilities: safety monitoring and automatic alarm/control.
- Food processing, medical/health and laboratory facilities: hygiene control where controlled disinfectant presence is required.
- Industrial and municipal wastewater treatment: process monitoring where chlorine/ClO2/O3 are used or generated.
