- Outputs and interfaces: RS485 (Modbus), two 4–20 mA outputs, two alarm relays; power 90–260 V AC; IP65 enclosure; panel size 144×144×104 mm.

Product Features

- Inductive (toroidal) conductivity sensing for long life and low maintenance in corrosive media.

- Digital acid/base concentration sensor for fast, precise readings.

- Multi-parameter reporting: conductivity, TDS, salinity, NaCl and specific acid/base concentrations plus temperature.

- Standard industrial communication: RS485 (Modbus), dual 4–20 mA outputs and two relay alarms for high/low setpoints.

- Built-in data recording and history-curve review for trend analysis.

- Wide input power range and IP65 protection for flexible site deployment.

Product Value

- Real-time, accurate monitoring of solution concentration enables tighter process control and consistent product quality.

- Reduces chemical waste and consumption by enabling timely dosing and fewer manual checks.

- Protects equipment (e.g., boilers, ion-exchange systems) by preventing out-of-spec acid/base concentrations.

- Easy integration into PLC/DCS systems for automation and centralized control.

- Historical data logging supports troubleshooting, compliance and process optimization efforts.

Product Advantages

- Robust inductive sensor design resists fouling and corrosion, lowering maintenance and replacement costs.

- Broad measurement range covers both dilute and concentrated acids (including concentrated sulfuric acid), making it versatile for many industries.

- Multiple industrial outputs and alarm relays simplify integration and immediate control actions.

- Compact, rugged IP65 enclosure and wide power compatibility enable flexible installation.

- Manufactured to recognized standards with experienced technical support from BOQU, ensuring quality and after-sales service.

Application Scenarios

- Thermal power plants: boiler tube pickling, chemical dosing and monitoring of circulating solutions.

- Chemical industry: concentration control in production reactors, acid/base handling and process lines.

- Ion-exchange and water treatment: monitoring regeneration baths and producing high-purity water.

- Brine, electroplating and salt processes: salinity and NaCl concentration control.

- Industrial wastewater and process control: continuous monitoring of corrosive streams, alarm-driven safety control and data logging for compliance.
