Water analyzer DAW501

nitrogenchlorinenitrate

Product Overview
The DAW501 Universal Transmitter is a versatile and reliable solution for water and gas detection. Designed to seamlessly integrate with various sensors, it offers accurate data monitoring, flexible configuration, and stable performance, making it an ideal partner for OEM water and gas detection applications.
Key Features

• Broad Sensor Compatibility: Freely connects with both digital and analog sensors, supporting multi-parameter measurement to meet diverse monitoring needs.
• Flexible Channel Configuration: Optional single-channel (for 1 sensor) or dual-channel (for 2 sensors) setup, effectively reducing equipment costs and saving installation space.
• Plug-and-Play Convenience: All digital sensor interfaces are ready for direct use; analog sensors only require type-specific modules. Enables fast and easy electrode installation and replacement.
• Comprehensive Functionality: Displays real-time sensor data, supports 4-20mA analog output configuration and calibration, and offers relay control and MODBUS RS485 digital communication.
• Durable & Reliable Design: Features an IP66/NEMA4X waterproof housing, suitable for both indoor and outdoor use, with strong resistance to environmental interference.
• Rich Data Management: Stores up to 120 million data points (at 5-second intervals) and supports historical data query, facilitating traceability and analysis.
• User-Friendly Operation: 128*64 dot-matrix LCD with LED backlight for clear display under direct sunlight; intuitive panel keys and multi-language (Chinese/English) support simplify operation.

Measurable Parameters
pH, Dissolved Oxygen (DO), Oxidation-Reduction Potential (ORP), Conductance, Turbidity, Suspended Solids (SS), Chlorophyll, Blue-Green Algae, Residual Chlorine, UVCOD, Ionic Ammonia Nitrogen, Nitrate, and Transparency.
Applications

• Sewage treatment plants and waterworks
• Environmental monitoring stations
• Surface water and groundwater monitoring
• Aquaculture industry
• Industrial process monitoring
