BOQU Online Acid Meter Online Acid Meter Supply
Product Overview
- Model: BOQU SJG-2083CS Online Acid and Alkali Concentration Meter.
- Purpose: continuous online measurement of acid/alkali concentration and related conductivity parameters.
- Core sensing: inductive conductivity sensor with digital processing.
- Key specs: conductivity 0–2000 mS/cm, TDS 0–130,000 mg/L, salinity 0–80 g/L, NaOH ranges 0.00–25.99% and 15.13–50.00%, temperature -40 to 150 °C; accuracy ±1% FS and ±0.5 °C. Power 90–260 V AC. Size 144×144×104 mm. Protection IP65.
Product Features
- Inductive conductivity sensing for long life and low maintenance (no direct electrode fouling).
- High-speed digital sensor delivers fast, precise acid/base concentration readings.
- Multi-parameter outputs: conductivity, TDS, salinity, NaCl, HCl, HNO3, NaOH, H2SO4, KOH concentrations and temperature.
- Communications and control: RS485 (Modbus), two 4–20 mA outputs and two adjustable relay alarms (5 A).
- Built-in data recording and historical curve display for trend review.
- Wide supply voltage (90–260 V AC) for global compatibility and IP65 protection for harsh environments.
Product Value
- Accurate, real-time monitoring of acid/alkali concentrations improves process control and product quality.
- Reduces manual sampling and laboratory testing costs and response time.
- Early alarm capability prevents over- or under-dosing, protecting equipment and reducing chemical waste.
- Durable inductive design lowers maintenance and sensor replacement costs.
- Data logging supports traceability, compliance and process optimization.
Product Advantages
- Industry-conforming manufacturing with 100% conformance testing and quality supervision.
- Robust hardware: wide power range, IP65 enclosure, and reliable relay/analog/serial interfaces for industrial integration.
- Multifunctional measurement capability replaces multiple single-parameter instruments.
- User-friendly features: on-device data history, alarms and standardized Modbus output for easy SCADA/DCS connection.
- Backed by BOQU’s service network, experienced R&D/production team, competitive pricing and fast reply commitment.
Application Scenarios
- Chemical plants: monitoring and control of acid/base concentration in reaction baths and process streams.
- Electroplating, metal finishing and surface treatment baths (acid/alkaline concentration control).
- Wastewater and neutralization systems for continuous acid/alkali dosing control.
- Food, pharmaceutical and textile industries where precise salt/acid control is required (brine, dyeing, cleaning).
- Desalination, cooling towers and industrial water treatment where conductivity/TDS/salinity monitoring is needed.
