BOQU NaCL Meter Company

Product Overview

- Model: SJG-2083CS Online Acid and Alkali Concentration Meter by BOQU (Shanghai Boqu Instrument Co., Ltd.).

- Online digital concentration meter based on a digital inductive conductivity sensor for continuous, in-line measurement of conductivity and multiple chemical concentrations.

- Measures conductivity, TDS, salinity and specific concentrations (including NaCl, HCl, H2SO4, NaOH, KOH, HNO3 ranges) and temperature.

- Robust industrial design (panel size 144×144×104 mm, IP65 protection) with global power compatibility (90–260 V AC).

Product Features

- Measurement principle: inductive conductivity sensor for long life and low maintenance.

- Digital sensor technology for fast, high?precision readings.

- Multi-parameter outputs: standard RS485 (Modbus), two 4–20 mA outputs and two programmable relays (5 A).

- Wide measurement ranges (e.g., conductivity 0–2000 mS/cm; NaCl 0.00–25.00%; salinity 0–80 g/L) and temperature range ?40°C to 150°C.

- Built?in data recording/history curve function for trend review and diagnostics.

- High accuracy (±1% FS for concentration, ±0.5°C for temperature).

Product Value

- Enables continuous, real?time control of acid/alkali and salt concentrations to improve process stability and product quality.

- Reduces manual sampling and laboratory testing workload, saving labor and time.

- Supports process automation and safety by providing alarms and remote communications for fast response.

- Helps minimize chemical overusage and waste through accurate dosing control, lowering operational costs.

- Useful for compliance, process documentation and troubleshooting via recorded data and communication outputs.

Product Advantages

- Durable inductive sensor with long service life and minimal maintenance requirements.

- Wide dynamic measurement ranges covering dilute to relatively concentrated solutions, including multiple acids, bases and NaCl/salinity.

- Flexible integration: standard industrial outputs (Modbus RS485, 4–20 mA) and relay alarms simplify connection to PLCs and control systems.

- IP65 protection and wide power input make it suitable for varied industrial environments and installations.

- Backed by BOQU’s manufacturing and quality control team, with customer support responsiveness (company commits to reply within 8 hours).

Application Scenarios

- Thermal power plants: monitoring and control of boiler water treatment and pickling solutions.

- Chemical industry: concentration control in production, mixing and storage processes.

- Water treatment and ion-exchange systems: monitoring regenerant and brine concentrations for high?purity water production.

- Desalination, salt solutions and salinity control processes (NaCl concentration monitoring).

- Any industrial process requiring continuous online monitoring of acid/base/salt concentration and temperature for process optimization, safety and automation.
