Product Description

KNF-400PRO Integrated Multi-parameter Water Quality Sensor

The KNF-400PRO multi-parameter sensor adopts a compact integrated design for a single unit, enabling simultaneous monitoring of six water quality parameters including dissolved oxygen, pH, conductivity, turbidity, depth and temperature. The sensor is equipped with an automatic cleaning brush that cleans the measurement surface of attached substances, removes bubbles and inhibits microbial growth, effectively ensuring the stability and accuracy of long-term online measurement.

It comfortably meets the monitoring requirements of various water environment conditions such as wastewater treatment, surface water, marine environment and groundwater. After years of market validation and continuous technological iteration, the entire machine offers excellent long-term stability and reliability, allowing for continuous unmanned operation with a maintenance cycle of up to several months.

Sensor Features

Full digital sensor with RS485 output and standard MODBUS protocol
Supports on-site calibration - highly flexible and capable of adapting to different water qualities, further enhancing measurement accuracy
Can be directly immersed in the measured water body, suitable for all-weather, uninterrupted online monitoring, simplifying system configuration
Equipped with an automatic cleaning device to effectively prevent biological adhesion and dirt deposition, significantly reducing maintenance and the frequency of manual cleaning
Integrated body design capable of monitoring six parameters including dissolved oxygen, pH, conductivity, turbidity, depth and temperature
