Horiba U-52 Multiparameter Water Quality Meter

The HORIBA U-52 multiparameter water quality meter is a field-ready, portable monitoring system that delivers accurate, real-time measurements across multiple critical water quality parameters from a single integrated probe. Built for environmental professionals, remediation teams, groundwater consultants and water treatment operators, the U-52 monitors and logs water quality simultaneously in rivers, groundwater wells, lakes, wastewater systems and industrial discharge environments. The U-50 Series platform integrates multiple sensors into one probe, letting you measure and display up to 11 parameters at once — which cuts setup time and simplifies field workflows considerably. The rugged construction, automatic calibration and live on-screen display of every channel make it well suited to demanding field sampling and long-term monitoring programs. With EPA-compliant turbidity measurement, field-replaceable sensors and high-capacity onboard data storage, the U-52 helps you maintain data quality while maximizing time on site. Measured parameters pH ORP (redox potential) Dissolved oxygen (DO) Electrical conductivity Salinity Total dissolved solids (TDS) Seawater specific gravity Temperature Turbidity Water depth Applications Groundwater monitoring well sampling and low-flow purge stabilization Surface water surveys of rivers, lakes, streams and reservoirs Remediation site performance monitoring and site characterization Municipal and industrial wastewater and effluent discharge compliance Stormwater and turbidity monitoring at construction and discharge sites Coastal, estuarine and brackish water monitoring Drinking water source and raw intake monitoring Note: the configuration options below include probe, cable, handheld control unit and backpack. Choosing a cable length Match the cable to your deepest measuring point. Short cables suit surface water, flow cells and beaker readings; 10 m covers typical shallow monitoring wells; 30 m is for deep wells, reservoirs and full water-column profiling.
