Product Overview
- Model: SJG-2083CS Online Acid/Alkali Concentration Meter by BOQU Instrument.
- Purpose: continuous online measurement and control of acid, alkali and saline solutions using a digital inductive conductivity sensor.
- Measured parameters: conductivity, TDS, salinity, NaCl and concentrations of common acids and bases (H2SO4, HCl, HNO3, NaOH, KOH, etc.) plus temperature.
- Key specs: conductivity 0–2000 mS/cm; TDS 0–130,000 mg/L; salinity 0–80 g/L; sulfuric acid ranges given for dilute and concentrated; temperature ?40 to 150 °C; accuracy ±1% FS, ±0.5 °C.
- 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.
