Portable Water Quality Precision Monitoring Equipment
The Horiba U-53 is a field-deployable multiparameter water quality monitoring system designed for real-time assessment of surface water, groundwater, wastewater, and marine environments.
It integrates a multi-sensor probe with a handheld control unit, enabling simultaneous measurement of key physico-chemical parameters. The system supports both spot sampling and continuous monitoring applications.
The U-53 combines electrochemical, optical, and conductivity-based sensors within a single probe to deliver reliable water quality measurements. Automated calibration and onboard data logging support consistent data acquisition for environmental studies and compliance monitoring.
