KNF-400PRO Groundwater Quality Sensor Brings 6-in-1 Multi-Parameter Monitoring to Smart Water Management

As global demand for clean, reliable groundwater resources continues to rise, accurate and continuous water quality monitoring has become a top priority for environmental agencies, industrial operators and municipal utilities. To meet this challenge, we are pleased to announce the KNF-400PRO Integrated Multi-Parameter Water Quality Sensor — a compact, all-in-one groundwater quality sensor engineered to monitor six critical water parameters in a single unit.

Why Groundwater Quality Monitoring Matters

Groundwater supplies drinking water for a large share of the world's population and supports agriculture, industry and natural ecosystems. Contamination from nitrates, heavy metals, salinity intrusion and microbial growth can develop slowly and remain invisible without continuous monitoring. Traditional setups require multiple separate probes, complex wiring and frequent manual cleaning, which raises cost and reduces data reliability over time. The KNF-400PRO solves these problems with one integrated groundwater quality sensor that delivers stable, real-time data around the clock.

One Sensor, Six Parameters

The KNF-400PRO simultaneously measures dissolved oxygen, pH, conductivity (salinity and TDS), turbidity, depth and temperature. Its automatic cleaning brush wipes the measurement surface, removes bubbles and inhibits microbial growth, ensuring long-term accuracy and a maintenance cycle of up to several months — ideal for unmanned, continuous groundwater monitoring in remote wells and monitoring stations.

Key Features

• Full digital sensor with RS485 output and standard MODBUS protocol
• Integrated body design monitoring six parameters in one probe
• Automatic cleaning device prevents biofouling and dirt deposition
• Supports on-site calibration with calibration data stored inside the probe
• Can be directly immersed in the measured water body for all-weather, uninterrupted monitoring
• IP68 protection level and durable POM housing for harsh environments

Technical Specifications

Applications

• Groundwater monitoring and aquifer protection
