Online Conductivity Meter - for Potable Water - BOQU

Product Overview

- The BOQU DDG-2080X Online Conductivity / TDS Meter is an industrial-grade instrument for continuous measurement of conductivity (EC), resistivity, salinity, TDS and temperature.

- It is designed for panel, wall or pipe mounting, is IP65-rated for protection, and is supplied with mounting supports and a user manual. Power input is wide-range 90–260 VAC with low consumption (

Product Features

- Measurement ranges: EC 0.00 μS–2000 mS, resistivity 0.00–20.00 MΩ·cm, salinity 0.00–78.00 g/kg, TDS 0–133000 ppm; temperature ?10.0 to +130.0 °C.

- Accuracy: ±1% F.S. for main parameters; temperature accuracy ±0.2 °C; adjustable cell constant 0.001–20.000.

- Outputs & communication: two isolated 4–20 mA outputs (max load 500 Ω), RS485 Modbus RTU, and up to three relay contacts (max 5 A/250 VAC or 5 A/30 VDC).

- Additional functions: large data-logger capacity (500,000 records), configurable cleaning cycles and relay delays, backlit dot-matrix display, multilingual UI (English/simplified/traditional Chinese).

Product Value

- Provides reliable, continuous multi-parameter monitoring (EC, resistivity, salinity, TDS and temperature) in a single instrument, reducing the need for multiple meters and simplifying system integration.

- Industrial I/O (isolated 4–20 mA, RS485 Modbus, relays) enables easy connection to PLCs, SCADA and data-collection systems for process control and regulatory reporting.

- Robust design (IP65, wide power range) and onboard data logging support long-term, low-maintenance operation and traceable record-keeping.

Product Advantages

- Very wide measurement ranges and an adjustable cell constant support diverse water types from ultra-pure to highly saline.

- High accuracy (±1% F.S.) and precise temperature compensation (Pt1000/NTC30K) ensure dependable readings.

- Industrial communication and control features (isolated outputs, Modbus RTU, configurable relays and cleaning cycles) give flexibility for automated control and alarm handling.

- Large on-board memory, multilingual interface and versatile mounting options make it adaptable to varied installations and user needs.

Application Scenarios

- Potable/drinking water monitoring and distribution systems.

- Wastewater and environmental monitoring programs.

- Industrial process water control (e.g., cooling towers, boilers, RO systems).

- Food and beverage production, fermentation and other sanitary process control.

- Laboratories and water quality monitoring stations where continuous, recorded conductivity/TDS/resistivity data are required.
