Product Overview
1) Product overview
Product Features
- The SJG-2083CS is an online digital acid/alkali concentration meter (marketed here as the HCl meter) from BOQU Instrument. It uses a digital inductive conductivity sensor to provide continuous, real‑time measurement of solution concentration and temperature. It is a panel‑mount, IP65 protected instrument designed for industrial process control.

Product Advantages
- Inductive digital conductivity sensor for long life and low maintenance.
Application Scenarios
- Multi-parameter measurement: conductivity (0–2000 mS/cm), TDS (0–130,000 mg/L), salinity (0–80 g/L) and calculated concentrations for NaCl, HCl, HNO3, NaOH, KOH (0–26% and 26–42% ranges shown), H2SO4, etc.; temperature range −40 °C to 150 °C.
- Accuracy ±1% FS for concentration, ±0.5 °C for temperature.
- Outputs and communications: RS485 Modbus, two isolated 4–20 mA outputs, and two alarm relays (5 A).
- Built‑in data recording/history curve, wide input power (90–260 V AC), compact size (144×144×104 mm).
3) Product value
- Provides continuous, online concentration control to optimize chemical dosing and process consistency.
- Improves safety and compliance by enabling alarm thresholds and uninterrupted monitoring.
- Reduces operating cost through durable inductive sensor design (less maintenance and replacement) and accurate measurement that minimizes chemical waste.
- Facilitates data logging and remote integration for process automation and quality traceability.
4) Product advantages
- Durable inductive sensing technology and fully digital sensor deliver faster, more stable and longer-lasting performance than many contact-type probes.
- Versatile: supports multiple chemistries (acids and alkalis) and derived parameters in one device.
- Flexible integration with industry controls via Modbus, 4–20 mA outputs and relay alarms.
- Rugged, compact, panel-mount housing with IP65 protection suitable for industrial environments.
- Wide supply voltage compatibility for international use.
5) Application scenarios
- Thermal power plants (chemical dosing, boiler feedwater/pickling control).
- Chemical manufacturing and processing (acid/base concentration monitoring and control).
- Ion-exchange regeneration and high‑purity water production (monitoring regenerant concentration).
- Industrial water treatment, desalination and brine monitoring (salinity/NaCl measurement).
- Any continuous process requiring online acid/alkali concentration control, alarm notification and data recording (electroplating, pickling, wastewater, process automation).
