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.
