Expert in Water Quality Measurement and Water Treatment Project Since 2007
Product Overview
- SJG-2083CS Acid and Alkali Concentration Meter Controller by BOQU is an online smart digital instrument that measures acid/base and salt solution concentration using a digital inductive conductivity sensor.
- It supports a broad set of solution types (electrical conductivity, NaCl, HCl, HNO3, NaOH, KOH, dilute and concentrated H2SO4, etc.) for continuous, real‑time process monitoring and control.
- Designed for industrial use with IP65 protection, wide supply voltage (90–260 V AC) and compact panel size.
Product Features
- Inductive conductivity sensing for long life and low maintenance; dedicated digital acid‑base concentration sensor for fast, precise readings.
- Measurement ranges: conductivity 0–2000 mS/cm, TDS 0–130,000 mg/L, salinity 0–80 g/L; H2SO4 concentration ranges (0.00–30.25% and 91.91–100%); temperature −40 to 150 °C.
- Accuracy: ±1% FS (concentration) and ±0.5 °C (temperature).
- Outputs and interfaces: RS‑485 Modbus, two isolated 4–20 mA outputs, two relay alarms (5 A, 250 V AC / 5 A, 30 V DC).
- Built‑in data recording and history curve display for trend review and diagnostics.
Product Value
- Enables continuous, online monitoring and precise control of acid/base and salt concentrations to improve process stability and product quality.
- Reduces manual sampling and reagent waste, lowering operating costs and safety risks in chemical handling.
- Fast, reliable measurements support automated process feedback and alarm actions, helping prevent over/under dosing and corrosive damage.
Product Advantages
- Robust inductive digital sensor technology: long service life, minimal maintenance, and high measurement reliability in harsh industrial fluids.
- Wide measurement ranges and high accuracy suitable for both dilute and concentrated solutions (including sulfuric acid).
- Multiple communication and control outputs (Modbus, 4–20 mA, relay) for easy integration into DCS/PLC and control loops.
- Industrial design: broad power compatibility, IP65 protection, data logging, and BOQU’s proven manufacturing/technical support.
Application Scenarios
- Thermal power plants (boiler water treatment, pickling solution preparation and control).
- Chemical production and process plants for monitoring/reactant concentration and safety control.
- Ion‑exchange and ultrapure water regeneration processes where regenerant concentration must be controlled.
- Any industrial continuous process requiring real‑time monitoring of acid/base/salinity (e.g., pickling, plating, neutralization, brine systems).
