RS-485 fluorescence dissolved oxygen sensor

Product Features

• Advanced Optical Fluorescence Technology
• Utilizes cutting-edge optical lifetime sensing that does not consume oxygen during measurement. It requires no minimum liquid flow rate, delivering highly stable and instant readings even in completely stagnant water.
• Membrane-Free & Low Maintenance
• Eliminates the hassle of traditional polarographic sensors. It features no electrolyte fluids, no internal membranes, and no regular calibration requirements, drastically reducing labor time and ownership costs.
• Anti-Interference RS485 Digital Communication
• Uses the industrial-standard Modbus RTU protocol (RS485) to convert sensor readings into noise-free digital data. It is 100% immune to electrical interference from nearby paddlewheels, water aerators, and heavy farm machinery.
• High-Accuracy Monitoring (±0.5% FS)
• Provides exceptional precision across its measurement range. Built-in intelligent software ensures stable data tracking without measurement drift, making it ideal for delicate aquatic life like shrimp and fish fries.
• Flexible Multi-Signal Outputs
• Supports standard digital RS485 communication along with multiple customizable analog options (4-20mA, 0-5V, 0-10V, or 1-5V), ensuring universal compatibility with various PLC systems, data loggers, and smart farm controllers.
• Industrial Waterproof Build
• Constructed from rugged, corrosion-resistant materials designed for prolonged submersion. The probe housing is built to withstand harsh, high-humidity, and demanding environments like commercial aquaculture ponds and industrial wastewater tanks.
• Long-Distance Transmission Capability
• Supports stable, lag-free data broadcasting over long distances up to 1,200 meters. You can easily daisy-chain multiple sensor nodes onto a single communication line to simplify your network wiring.
