Precision Conductivity, Salinity & TDS Measurement—Engineered for Real-World Water Applications
Whether you’re monitoring seawater in a shrimp pond, optimizing fertigation in agriculture, or ensuring water quality in municipal pipelines, accurate conductivity measurement is non-negotiable. The KNF-102HPRO digital conductivity/salinity/TDS sensor combines advanced 4-electrode technology, rugged dual-installation flexibility, and field-serviceable design—all validated by real-world deployment across wastewater, aquaculture, and environmental monitoring projects worldwide.

Key Innovations & Technical Advantages
✅ True 4-Electrode Graphite Design – Minimizes Polarization & Fouling
Unlike 2-electrode sensors that degrade quickly in high-conductivity or dirty water, the KNF-102HPRO uses four graphite electrodes to separate current injection from voltage measurement. This dramatically:
Reduces polarization error
Extends calibration intervals
Maintains accuracy from ultra-pure water (0.1 μS/cm) to seawater (200 mS/cm)
✅ Field-Replacement Probe – Cut Downtime & Cost
The sensing head is fully replaceable in minutes—no need to replace the entire transmitter or rewire the system. Ideal for remote sites or high-utilization operations.
✅ Dual Installation Flexibility
Inline Pipe Mounting: Use with optional Y-type 3-way fitting with face seal for leak-free integration into DN15–DN100 pipelines. Rated up to 6 bar (87 psi).
Submersible Deployment: Fully sealed IP68 housing supports continuous operation at depths up to 50 meters—perfect for wells, reservoirs, ocean buoys, or fish tanks.

Easy Integration & Maintenance
Output: RS-485 with MODBUS RTU protocol – plug-and-play with PLCs, SCADA, or IoT gateways
Power: 9–28 VDC, low consumption (<1W)
Optional Accessories:
Y-type 3-way flow cell with EPDM/PTFE face seal
Automatic cleaning wiper (for biofouling-prone waters)
Stainless steel mounting bracket for submersible use
