Product Description

KNF-600PRO Online Deep-Water Multi-Parameter Water Quality Sensor

The Kainafu KNF-600PRO is a purpose-built online deep-water multi-parameter sensor engineered for deep lakes, marine monitoring, underground wells and harsh wastewater. It features a robust pressure-resistant structure and self-developed titanium alloy watertight connectors, withstanding water pressure up to 20 bar (200 m depth) for stable long-term operation.

KNF-600PRO Online Deep-Water Multi-Parameter Sensor 200m 20 Bar Titanium RS485 MODBUS IP68

Built for Deep Water & Wells

0-200 m measurement depth — downhole, well and marine ready.
20 bar pressure resistance — deep-water aviation connector with titanium alloy plug.
Integrated titanium alloy body — corrosion-resistant, high-strength, high-temperature and impact resistant for up to 200 m underwater.
6 standardized sensor interfaces + 1 central cleaning brush — freely combine dissolved oxygen, pH/ORP, conductivity (salinity), turbidity, chlorophyll, cyanobacteria and oil-in-water probes.
Automatic cleaning device — cleans at set intervals to remove bubbles and biofouling, ideal for long-term unmanned deep-water monitoring.
RS-485 output, MODBUS protocol — easy integration with data acquisition platforms and automatic water quality monitoring stations.
Field-replaceable, on-site calibration — every calibration parameter is stored inside its independent probe.
IP68 protection with 30 m default waterproof cable (customizable).
