Product Overview
1) Product overview
Product Features
- Model: SJG-2083CS Online Acid-Alkali Concentration Meter (BOQU).
Product Value
- An online digital concentration meter using a digital inductive conductivity sensor to measure conductivity-based concentrations of acids, alkalis and salts.
Product Advantages
- Measures multiple parameters (conductivity, TDS, salinity, NaCl, HCl, HNO3, NaOH, KOH, H2SO4 and temperature) and is supplied as a compact IP65 instrument (144 × 144 × 104 mm) for continuous process monitoring.
Application Scenarios
2) Product features
- Inductive conductivity sensing for long service life and low maintenance.
- Digital acid/base concentration sensor with fast, precise response.
- Measurement ranges: conductivity 0–2000 mS/cm, TDS 0–130,000 mg/L, salinity 0–80 g/L, HNO3 up to about 30% (manufacturer-stated range), temperature -40°C to 150°C.
- Accuracy: ±1% FS (concentration), ±0.5°C (temperature).
- Outputs/communication: RS485 (Modbus), two 4–20 mA outputs and two alarm relays (5 A; 250 V AC / 5 A; 30 V DC).
- Built-in data recording and history-curve capability; wide supply voltage 90–260 V AC, 50/60 Hz.
3) Product value
- Enables real-time, continuous monitoring and control of acid/alkali concentrations to optimize chemical dosing and process stability.

- Low-maintenance inductive sensing reduces downtime and lifetime operating costs.
- Data logging and alarm outputs support process traceability and automation, aiding compliance and quality assurance.
4) Product advantages
- Versatile multi-parameter monitoring (conductivity, TDS, salinity and specific acid/alkali concentrations) in one device.
- Robust inductive digital sensor technology for long life, high precision and minimal maintenance.
- Flexible integration: Modbus RS485, dual 4–20 mA outputs and alarm relays for direct control and SCADA connection.
- Wide electrical input range and IP65 protection for reliable use across different sites and environments.
- Compact panel-mount form factor and easy-to-use data recording for straightforward installation and operational review.
5) Application scenarios
- Thermal power plants (chemical dosing control, boiler water treatment and pipe pickling).
- Chemical industry processes requiring continuous acid/alkali concentration control.
- Ion exchange and water purification plants (regeneration liquid monitoring for high-purity water production).
- Paper and textile production (process baths where acid/alkali concentration affects product quality).
- Any industrial process or wastewater application needing online monitoring and automated control of acid, alkali or salt concentrations.
