Product Overview
1) Product overview
Product Features
The BOQU PFG-3085 online ion meter is a microcomputer-based industrial analyzer designed for continuous monitoring of a range of ions (including NO3– nitrate) and temperature. Marketed under BOQU’s nitrate ion meter line, it is a multilingual, panel/wall/pipe-mountable instrument built for industrial and municipal water applications.

Product Advantages
- Measures ion concentration (0.00–5000 ppm) with multi-tier resolution (0.01 / 0.1 / 1 ppm) and high accuracy options (±0.01 / ±0.1 / ±1 ppm).
Application Scenarios
- High-impedance input (>10^12 Ω) with mV input 0.00–1000.00 mV.
- Temperature compensation (Pt1000 / NTC10K) over −10.0 to +130.0 °C; temp accuracy ±0.2 °C.
- Two isolated 4–20 mA outputs (ion and temp), RS485 Modbus RTU, and up to three programmable relays (5 A, 250 VAC / 30 VDC).
- Built-in data logger (up to 500,000 records), cleaning control (programmable ON/OFF), backlit dot-matrix display, IP65 enclosure, low power (90–260 VAC,
3) Product value
- Enables continuous, accurate nitrate (and other ion) monitoring for process control, compliance and early detection of anomalies.
- Reduces manual sampling/lab costs and improves operational responsiveness with real-time outputs and remote digital integration (Modbus).
- Large on-board data logging provides traceability for audits and historical analysis.
- Rugged IP65 design and multiple mounting options support reliable long-term deployment in industrial environments.
4) Product advantages
- Versatile: supports multiple ion types (F–, Cl–, Mg2+, Ca2+, NO3–, NH4+, hardness, etc.) and automatically adapts units per sensor.
- Industrial-grade electronics: isolated current outputs, high input impedance, wide temp compensation, and robust relay capacity.
- Extensive features in one unit: language selection (English / Simp. Chinese / Trad. Chinese), programmable cleaning, large data memory, and Modbus communications.
- Manufactured by Shanghai Boqu with established production capacity and quality-focused assembly.
5) Application scenarios
- Industrial wastewater treatment and process monitoring
- Municipal drinking water quality control and distribution monitoring
- Power plants and boiler/feedwater chemistry control
- Electroplating and other surface-finishing plants
- Environmental monitoring stations, laboratories, and any facility requiring continuous nitrate or general ion monitoring and data logging
