Online Conductivity Meter Salinity Meter for Irrigation Quality Assurance
Product Overview
1) Product overview
Product Features
- Model: DDG-2080X Online Conductivity / Salinity Meter designed for continuous monitoring and control of irrigation water quality (also suitable for industrial and environmental use).
Product Value
- Measures: conductivity (EC), resistivity, salinity, TDS and temperature in one instrument.
Product Advantages
- Mounting: panel, wall or pipe mount; rugged IP65 enclosure for field and process environments.
Application Scenarios
2) 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 0–133,000 ppm.
- Temperature: -10.0 to +130.0 °C, temp compensation via Pt1000 or NTC30K, temp resolution 0.1 °C, temp accuracy ±0.2 °C.
- Outputs & communication: two isolated 4–20 mA outputs (max 500 Ω), RS485 Modbus RTU (baud 9600/19200/38400).
- Control & alarms: up to three relays (multi-function), relay rating 5A/250VAC or 5A/30VDC, relay delay and programmable cleaning cycle.
- Data & UI: internal datalogger (up to 500,000 records), backlit dot‑matrix display, multilingual menu (English / Simplified & Traditional Chinese).
3) Product value
- Enables continuous, real‑time monitoring and automated control of irrigation water quality to protect crops and optimize fertilizer dosing (fertigation).
- Supports regulatory compliance and traceability through onboard datalogging and remote Modbus communication for SCADA/PLC integration.
- Reduces manual sampling and maintenance with programmable cleaning cycles and robust field protection (IP65), improving uptime and operational efficiency.
4) Product advantages
- Multi-parameter capability in a single instrument reduces the need for multiple sensors/meters.
- High accuracy and wide measurement ranges suit very low to very high conductivity/salinity waters.
- Industrial-grade outputs (isolated 4–20 mA) and Modbus RTU enable reliable integration into existing control systems.
- Large datalog capacity and flexible alarm/relay logic provide strong local control and historical record keeping.
- Backed by manufacturer quality control and options for different installation styles, offering a durable, field-ready solution.
5) Application scenarios
- Irrigation and fertigation quality assurance in agriculture and greenhouse operations.
- Wastewater monitoring and treatment process control.
- Drinking water quality monitoring and distribution system checks.
- Food and beverage production, fermentation control and general process water monitoring.
- Environmental monitoring, aquaculture, desalination pre/post checks and other industrial water systems.
