Alkali Concentration Meter by BOQU
Product Overview
1) Product overview
Product Features
- Model: SJG-2083CS Online Acid/Alkali (NaCl) Concentration Meter by BOQU.
Product Value
- Purpose: an online smart digital concentration meter using a digital inductive conductivity sensor to measure conductivity-related parameters and estimate concentrations of various acids, alkalis and salts (e.g., NaCl, HCl, HNO3, NaOH, KOH, H2SO4).
Product Advantages
- Key specs (high level): conductivity 0–2000 mS/cm, NaCl 0.00–25.00%, TDS 0–130,000 mg/L, salinity 0–80 g/L, temperature range ?40 to 150 °C, accuracy ±1% FS (±0.5 °C for temperature).
Application Scenarios
2) Product features
- Inductive conductivity sensing for long sensor life and low maintenance.
- Digital acid/base concentration sensor for fast and precise measurement.
- Multi-parameter measurement: conductivity, TDS, salinity, NaCl and common acid/alkali concentrations plus temperature.
- Standard communications and outputs: RS485 (Modbus), two isolated 4–20 mA outputs and two alarm relays (high/low).
- Built-in data recording and history-curve capability for trend review.
- Rugged design: wide power input (90–260 V AC, 50/60 Hz) and IP65 enclosure.
3) Product value
- Continuous online monitoring enables tighter process control and faster response to concentration changes.
- Improves safety and compliance by keeping acid/alkali concentrations within set limits and triggering alarms.
- Lowers maintenance and operating cost thanks to inductive sensor durability and digital stability.
- Supports process optimization (e.g., chemical dosing, regeneration and pickling) and quality assurance in industrial water and chemical processes.
- Easy integration into plant control systems via Modbus and standard analog outputs.
4) Product advantages
- High accuracy and stability for reliable concentration readings across a wide range of solutions and concentrations.
- Robust sensing technology (inductive digital sensor) yields long service life and fewer field interventions.
- Flexible outputs and alarms allow immediate automation and control or direct operator notification.
- Wide measurement ranges (conductivity, TDS, salinity, NaCl, various acids/alkalis) reduce need for multiple instruments.
- Compact panel-mounted form (144×144×104 mm) with IP65 protection suitable for industrial environments.
5) Application scenarios
- Thermal power plants: monitor and control boiler water treatment, pickling solution concentration and feedwater chemistry.
- Chemical industry: continuous concentration monitoring in reactive process streams and dosing systems.
- Water treatment and purification: ion-exchange resin regeneration control and high-purity water production.
- Salt production and brine monitoring: NaCl concentration control in brine and salinity processes.
- Any industrial process requiring online monitoring of acid/alkali/salt concentrations for process safety, quality control and automation.
