Kainafu Releases KNF-500PRO Self-Cleaning Water Quality Sensor for Unmanned Online Monitoring

Kainafu has officially introduced the KNF-500PRO self cleaning water quality sensor, an online multi-parameter monitoring platform built on a fully modular probe architecture. Every single-parameter sensor is an independent RS485 digital probe that seals water-tightly onto a central body, and calibration data is stored inside each probe so that field calibration, replacement and maintenance can be completed on site without dismantling the whole instrument. One 84 mm × 476 mm housing accepts up to six probes and seven parameters, which makes the platform equally suitable for a wastewater aeration basin and a marine aquaculture cage.

Why Self-Cleaning Decides Data Quality

Fouling is the single most common reason online water quality data drifts. Biofilm, micro-bubbles, algae and sediment settle on optical windows and electrochemical surfaces within days, and the resulting bias is usually invisible to the operator until a compliance report is rejected. The KNF-500PRO addresses this at the hardware level: a central automatic cleaning brush sweeps every installed probe at a programmable interval, 30 minutes by default, removing bubbles and contamination before they harden into a coating. Combined with titanium alloy, POM and anti-fouling copper construction, the result is a sensor that keeps its accuracy through long unmanned deployment cycles instead of asking a technician to climb a ladder every week.

Core Capabilities

• RS485 output with standard MODBUS protocol — direct connection to data acquisition platforms, PLC/SCADA systems and automatic water quality monitoring stations.
• Up to six freely selectable probes — dissolved oxygen, conductivity (salinity), turbidity, pH, ORP, chlorophyll, blue-green algae, water oil, ammonia nitrogen and depth can be combined on demand.
• Field-replaceable, individually calibrated probes — each probe is removed and calibrated directly, cutting downtime and spare-part cost.
• Built-in fault alarms — the mother unit reports power supply, communication and cleaning-brush abnormalities so that a silent failure never becomes a data gap.
• IP68 protection, 0–30 m working depth — continuous immersion in wastewater, surface water, groundwater and seawater.
• Low power draw — 0.8 W with the brush idle and 2 W while rotating, well within the budget of solar and battery-powered remote stations.

Typical Applications

The platform is deployed in municipal and industrial wastewater treatment plants, river and surface-water monitoring networks, groundwater observation wells, marine and freshwater aquaculture, and drinking-water source protection zones — wherever continuous, unattended data is required for months at a time. Because probe combinations are configurable at order stage, a single SKU family covers nutrient removal control, algal bloom early warning and salinity intrusion monitoring.

Availability

The KNF-500PRO is available now with a minimum order quantity of one set, 7–15 working days lead time and a supply capacity of 500 sets per month. OEM branding, custom cable lengths and bespoke probe combinations are supported. Distributors and system integrators are invited to contact Kainafu for probe selection guidance and bulk pricing.
