Industrial Conductivity Meter by BOQU-1

Product Overview

1) Product overview

Product Features

- Model: DDG-2080PRO Industrial/online conductivity meter from BOQU (Shanghai Boqu Instrument Co., Ltd.).

Product Value

- Purpose: Continuous, panel/wall/pipe-mounted monitoring and control of conductivity-related water quality parameters for water treatment and industrial processes.

Product Advantages

- Measurements: Conductivity, TDS, resistivity, salinity and temperature with built-in temperature compensation options (PT1000 / NTC10K).

Application Scenarios

- Physical: ABS flame-retardant housing (V0), IP65 protection, dimensions 144 × 144 × 104 mm (cutout 138 × 138 mm). Local data logger stores 1000 records. Languages: English / Simplified Chinese.

2) Product features

- Multi-parameter measurement: Conductivity, TDS, resistivity, salinity and temperature in one instrument.

- Very wide measurement ranges (examples): 0.00 ?S/cm – 2,000,000 ?S/cm (0.00 ?S/cm – 2000.00 mS/cm), salinity up to 80 g/L, TDS up to 130,000 mg/L, resistivity up to 20 MΩ, temperature ?40.0 °C – 200.0 °C.

- Accuracy: ±1% (conductivity) and ±0.2 °C (temperature).

- Outputs & control: two isolated 4–20 mA outputs, RS485 Modbus RTU communication, two configurable relays (5 A @ 250 VAC / 5 A @ 30 V DC).

- Flexible installation: panel, wall or pipe mounted; supports contact conductivity sensors; low power consumption (~4 W) and wide AC supply (90–260 V AC).

3) Product value

- Provides reliable, continuous monitoring to support process control in water treatment, ensuring product quality and safety (drinking water, boiler feed, ultrapure water, etc.).

- Wide dynamic range and multi-parameter capability reduce the need for multiple instruments—lower capital and maintenance costs.

- Standard industrial interfaces (4–20 mA, Modbus, relays) simplify integration into plant control systems and automation.

- Robust construction and quality-controlled manufacturing increase service life and lower long-term operating costs.

4) Product advantages

- Comprehensive functionality: simultaneous measurement of several related water-quality parameters in one unit.

- Exceptional range and versatility: suitable from deionized/ultrapure water up to highly saline/brine conditions.

- Easy system integration: analog outputs and RS485 Modbus for SCADA/PLC connectivity plus alarm relays for local control.

- Durable and user-friendly: IP65 protection, flame-retardant casing, multiple mounting options, built-in data logger and multilingual UI.

- Cost-effective: designed to deliver reliable performance at a competitive price point for industrial applications.

5) Application scenarios

- Water and wastewater treatment: monitoring of process streams, treated effluent and control of dosing/bleed cycles.

- Power & boiler plants: conductivity/resistivity control of boiler feedwater and condensate systems.

- Ultrapure/deionized water systems: quality monitoring in semiconductor, pharmaceutical and laboratory water systems.

- Food & beverage and fermentation: process control where salinity, TDS and conductivity affect product quality.

- Environmental monitoring and municipal drinking water distribution: continuous tracking of dissolved solids and contamination events.

- Chemical processing, desalination and brine management: broad-range measurement capability suits high-salinity streams.
