Expert in Water Quality Measurement and Water Treatment Project Since 2007
Customized Oxygen Probe Sensor High Qualtiy for Different Industries
Product Overview
- High-quality, customizable optical dissolved oxygen probe (model DOG-209FYD(S)) designed for diverse industrial needs.
- Uses fluorescence-based measurement (no oxygen consumption), with measuring range 0–20 mg/L (ppm) and temperature range 0–45°C.
- Key specs: DO accuracy ±3%, temperature ±0.5°C, pressure ≤0.3 MPa, IP68/NEMA6P protection, MODBUS RS485 communication, 10 m cable. Materials: SUS316L + PVC (standard) or titanium for seawater; Viton O-ring.
- Supports automatic air and sample calibration and is built for continuous online monitoring.
Product Features
- Fluorescence-based oxygen-sensitive film for stable, repeatable readings and minimal maintenance.
- Non-consumptive measurement method reduces interference and drift.
- Patented, fully enclosed rugged design for durability and waterproof operation (IP68).
- Plug-and-play installation, simple calibration, visual alarm/warning outputs and customizable prompt messages.
- Standard industrial communication (MODBUS RS485) for easy integration.
Product Value
- Provides reliable, real-time dissolved oxygen data to support process control and regulatory compliance.
- Reduces maintenance and operational costs through long-term stability and low recalibration needs.
- Improves operational safety and decision-making with built-in alarms and clear status prompts.
- Customization options (materials, messaging, configuration) allow fit-for-purpose deployment across industries.
Product Advantages
- Advanced fluorescence technique delivers stable, accurate DO measurements without consuming oxygen.
- Robust construction and seawater-capable materials (titanium option) expand applicability and lifetime in harsh environments.
