Deploy a Full-Featured Water Quality Monitoring Station—Without Building a Station
Traditional water monitoring requires land acquisition, concrete foundations, power grid connection, and months of construction. The KNF-407 4G River Monitoring System eliminates all that.
This fully integrated, cabinet-style extractive water quality station packs everything into a single weatherproof enclosure: sensors, auto-sampler, data logger, 4G/NB-IoT transmitter, and self-cleaning system. Deploy it beside a river, lake, or outfall pipe in under a day—and start streaming real-time data to your cloud dashboard.
Designed for municipal agencies, environmental bureaus, industrial facilities, and smart city projects, the KNF-407 delivers lab-grade multi-parameter monitoring at a fraction of the cost and footprint of conventional stations.

True 4G/NB-IoT Cloud Connectivity
Real-time data transmission via 4G LTE or NB-IoT (global bands supported)
Connects seamlessly to Kainafu Water Quality Cloud Platform
View live data, set alarms, generate reports, and download historical records from any device

Up to 12 Parameters – Fully Customizable
Select from:
→ Temperature, Turbidity, pH, Conductivity, Dissolved Oxygen (DO)
→ Suspended Solids (SS), Color, COD, TOC
→ Chlorophyll-a, Blue-Green Algae (Phycocyanin/Phycoerythrin)
All sensors are CE-certified and validated by CNAS-accredited lab reports.

Fully Automated Operation
Auto water intake from river/lake via submersible pump
Self-cleaning flow cell prevents biofouling and sediment buildup
Auto drainage after each measurement cycle
Unattended operation for weeks between maintenance visits
Smart Auto-Sampling System
Event-triggered sampling: Automatically collect water samples when parameters exceed user-defined thresholds (e.g., high COD, low DO)
Time-based sampling: Schedule regular sample collection (e.g., every 6 hours)
Preserves samples in cooled compartment (optional) for lab verification
All-in-One, Zero Civil Works
No need for land approval, building permits, or on-site construction
<1 m² footprint – fits on a small concrete pad or even a floating platform
Solar-ready design (optional) for off-grid deployment
