Kainafu Releases the KNF-600PRO 200m Depth Water Quality Sensor for Deep-Water Monitoring

Kainafu has officially released the KNF-600PRO online deep-water multi-parameter water quality sensor, a purpose-built instrument engineered to deliver accurate, continuous monitoring at depths of up to 200 metres. Combining a pressure-resistant structure with self-developed titanium alloy watertight connectors and an automatic cleaning brush, the new sensor gives operators in aquaculture, marine research, groundwater management and industrial wastewater a dependable way to collect multi-parameter data in the most demanding underwater conditions.

Engineered for the Deep

The KNF-600PRO is designed around the realities of deep-water deployment. Its integrated titanium alloy body is corrosion-resistant, high-strength and impact-resistant, allowing stable long-term operation at a 200m depth water quality sensor rating. A deep-water aviation connector with a titanium alloy plug withstands water pressure up to 20 bar, while the default 30-metre waterproof cable (customisable) keeps signal integrity intact from the seabed to the surface. With an IP68 protection level, the unit is built to stay submerged and reliable year after year.

Key Highlights

• 0-200 m measurement depth — ready for downhole, deep-well and marine deployment.
• 20 bar pressure resistance — deep-water aviation connector with titanium alloy plug.
• 6 standardised 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 monitoring.
• RS-485 output with MODBUS protocol — simple integration with data acquisition platforms and automatic monitoring stations.
• Field-replaceable probes and on-site calibration — every calibration parameter is stored inside its independent probe.

Applications

The KNF-600PRO is suited to deep lakes, marine and ocean monitoring, underground wells and drilling, deep-water aquaculture, and harsh wastewater environments that require long-term, unmanned online monitoring. Because probes can be swapped in the field and calibrated on site, operators can tailor each deployment to the parameters that matter most — from dissolved oxygen and turbidity in aquaculture ponds to salinity and oil-in-water detection in coastal and industrial settings.
