Expert in Water Quality Measurement and Water Treatment Project Since 2007
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.
