Expert in Water Quality Measurement and Water Treatment Project Since 2007
Product Overview
- An online calcium-ion meter from BOQU (PXG-series design) for continuous, real-time monitoring of calcium ion concentration in water. Built around ion-selective electrode (ISE) technology with a molded PVC membrane sensor and a microcomputer-based controller, the instrument is designed for stable, long-term field use across multiple industries.
Product Features
- ISE sensor with replaceable PVC membrane and long working life (sensor life >1 year under normal conditions).
- Wide measurement capability (product details specify a broad range up to tens of thousands mg/L).
- Microcomputer controller with user-friendly interface, local data recording (up to 1,000 records) and history curve display.
- Outputs and control: 2 × 4–20 mA outputs, RS485 Modbus RTU communication, and 3 relay contacts (high/low control and cleaning) with adjustable relay delay.
- Built-in temperature measurement and compensation, anti-electromagnetic interference and surge protection, power-off data protection, IP65 housing, multiple installation options (panel/wall/pipe).
Product Value
- Low total cost of ownership through long sensor life and replaceable membranes that reduce maintenance and spare-part costs.
- Reliable, continuous monitoring enables better process control, regulatory compliance and faster response to water-quality changes.
- Flexible outputs and standard communication make integration into existing control systems and SCADA straightforward.
- Local data logging supports traceability and troubleshooting without immediate network connectivity.
Product Advantages
- Durable, validated structure for extended service life and stable performance.
- Advanced ISE technology provides selective and sensitive ion measurement with good resolution and accuracy.
- Robust electronics: wide power input (90–260V AC), anti-interference design, surge protection and power-off data retention.
- Practical features for field use: replaceable sensor membrane, multiple installation methods, IP65 protection and multilingual interface options.
Application Scenarios
- Environmental monitoring of surface water and effluents.
- Industrial process water monitoring and process control (chemical plants, power, metal finishing, etc.).
- Agricultural and aquaculture water quality control.
- Food & beverage production where ion levels must be tracked.
- Any facility requiring online, real-time calcium-ion monitoring and automatic control or alarm functions.
