KNF-103A Optical Dissolved Oxygen Sensor – Fluorescence-Based, No Membrane, RS485 MODBUS, IP68 for Aquaculture & WaterT

KNF-103A Optical Dissolved Oxygen Sensor – Fluorescence-Based, No Membrane, RS485 MODBUS, IP68 for Aquaculture & WaterT

2026-03-18

The KNF-103A dissolved oxygen sensor leverages advanced fluorescence quenching technology to deliver highly stable, accurate, and maintenance-free measurement of dissolved oxygen (DO) in water—without consuming oxygen or requiring flow.
Unlike traditional electrochemical (Clark-type) sensors, the KNF-103A features no membranes, no electrolytes, and no chemical interference, making it uniquely suited for long-term deployment in demanding environments such as intensive aquaculture (white shrimp, eel, osmanthus fish) and municipal or industrial water treatment systems.
Its optical detection method effectively rejects interference from pH fluctuations, ammonia nitrogen, sulfides, heavy metals, and other common water contaminants, ensuring reliable performance even in complex water matrices.

latest company news about KNF-103A Optical Dissolved Oxygen Sensor – Fluorescence-Based, No Membrane, RS485 MODBUS, IP68 for Aquaculture & WaterT 0

True Optical DO Measurement (Fluorescence Quenching)
Measures DO without consuming oxygen → accurate in stagnant or low-flow water
Immune to chemical interference from pH shifts, NH₃-N, H₂S, Cl⁻, heavy metals, etc.
Zero Maintenance Design
No membrane replacement
No electrolyte refilling
No frequent calibration required — ideal for remote or unattended sites
 Digital Output – RS485 with MODBUS RTU Protocol
Noise-resistant communication over long distances
Seamless integration with PLCs, SCADA, IoT platforms, and farm management systems
Optimized for Aquaculture Applications
Developed specifically for high-density shrimp, eel, and freshwater fish farms
Delivers superior cost-performance ratio vs. imported optical DO sensors
 Robust & Certified
IP68-rated for continuous submersion (up to 50m depth)
CE certified (EMC & LVD compliance)
Performance validated by CNAS-accredited laboratory reports

latest company news about KNF-103A Optical Dissolved Oxygen Sensor – Fluorescence-Based, No Membrane, RS485 MODBUS, IP68 for Aquaculture & WaterT 1

Why Choose KNF-103A for Your Aquaculture Operation?
“In high-density shrimp ponds, oxygen crashes can wipe out an entire crop overnight. The KNF-103A gives farmers peace of mind with lab-grade accuracy, zero consumables, and weeks of stable operation between calibrations—at half the cost of legacy optical sensors.”
