Conductivity Meter by BOQU

Product Overview

- The BOQU ECG-2090Pro is an online conductivity analyzer designed for continuous, industrial water quality monitoring.

- It measures conductivity plus derived parameters (TDS, resistivity, salinity) and temperature, and is compatible with BOQU contact conductivity sensors covering deionized water to highly saturated brines.

- The unit is available for panel, wall or pipe mounting, housed in ABS flame-retardant material with IP65 protection.

Product Features

- Multi-parameter measurement: Conductivity, TDS, Resistivity, Salinity and Temperature (with automatic temperature compensation via PT1000/NTC10K).

- Very wide measurement ranges (0.00 μS/cm to 2,000,000 μS/cm; salinity up to 80 g/L; TDS up to 130,000 mg/L; resistivity up to 20 MΩ; temperature ?40.0°C to 200.0°C depending on electrode).

- High stability and repeatability: accuracy ~1% and temperature accuracy ±0.2°C.

- Outputs and control: two isolated 4–20 mA outputs, RS485 Modbus RTU communication, two programmable relays (5 A).

- Built?in local data logger (1,000 records), compact dimensions for 92×92 mm panel cut-out, low power draw (4 W) and wide supply range (90–260 V AC).

Product Value

- Provides reliable, continuous process control by quickly indicating dissolved solids levels—critical for drinking water, industrial water, pure/ultrapure water and boiler systems.

- Broad dynamic range and sensor compatibility let one analyzer cover many applications from deionized water to saturated brines, reducing instrument count and cost.

- Standard outputs and Modbus make system integration straightforward for SCADA/DCS and remote monitoring, improving operational efficiency and regulatory compliance.

Product Advantages

- Wide measurement span and multi-parameter capability in a single compact instrument reduces instrumentation complexity.

- Robust construction (ABS V0, IP65) and multiple mounting options enable installation in harsh industrial environments.

- Flexible communications and control (dual 4–20 mA, RS485 Modbus, two relays) support both analog control loops and digital integration.

- Local data logging and proven BOQU sensor pairing deliver dependable, repeatable results; backed by BOQU’s design, R&D and customer support.

Application Scenarios

- Drinking water treatment and distribution monitoring.

- Industrial process water management, boiler feedwater control and cooling systems.

- Ultrapure water and semiconductor/ pharmaceutical rinse water quality control.

- Wastewater and environmental monitoring, including effluent control.

- Food & beverage process monitoring, fermentation control and desalination/brine concentration processes.
