Unlike the U-52 version, the HORIBA U-52G additionally features an integrated GPS function and water depth measurement. This allows water quality data to be assigned to a geographical measurement location and a specific depth. The integrated LED turbidity sensor also enables the measurement of water turbidity together with other relevant water quality parameters. The extended sensor cable enables measurements at deeper and difficult-to-access sampling locations. Combined with GPS and depth measurement, this supports the traceable documentation of water investigations at different locations and measurement depths.

HORIBA U-52 (2 m) – Multi-Parameter Meter with Turbidity Measurement for Mobile Water Analysis Monitoring Water Quality with One Measuring Instrument Reliable assessment of water quality often requires the measurement of several parameters. When these are determined individually using different measuring instruments, the effort required for measurements, documentation and evaluation increases. The HORIBA U-52 (2 m) from the U-50 series enables mobile multi-parameter measurements using a combined sensor probe. Various water parameters can be recorded within a single measurement process and displayed directly on the control unit. The instrument is particularly suitable for on-site investigations of surface waters, water quality monitoring and the inspection of water treatment processes. The U-52 version is equipped with a 2-metre sensor cable and enables the simultaneous display of up to 11 measured and calculated values. Unlike the U-51 version, the HORIBA U-52 additionally features an integrated LED turbidity sensor. This allows the turbidity of a water sample to be assessed together with other relevant water quality parameters. Measuring Parameters of the HORIBA U-52 The multi-parameter measuring instrument records important physical and chemical parameters for assessing water quality. pH value: Assessment of the acidic or alkaline characteristics of a water sample. Oxidation-Reduction Potential (ORP): Measurement of the electrochemical oxidation-reduction potential. Dissolved Oxygen (DO): Monitoring the oxygen content in water. Electrical Conductivity: Assessment of electrical conductivity as an indicator of dissolved ions. Salinity: Determination of salt content based on conductivity measurements. TDS: Determination of total dissolved solids as a calculated value. Seawater Specific Gravity: Calculated parameter for corresponding water samples. Temperature: Measurement of water temperature for the assessment and compensation of temperature-dependent parameters. Turbidity: Measurement of water turbidity using an LED-based optical sensor to assess suspended particles and changes in water clarity. Depending on the parameter, different display formats and calculated values can be shown. The U-52 version includes turbidity measurement but does not feature GPS or water depth measurement. Functions and Features The HORIBA U-52 combines a multifunctional sensor probe with a portable control unit. This allows several water parameters to be recorded within a single measurement process, without requiring a separate measuring instrument for each parameter. Integrated LED Turbidity Measurement The integrated turbidity sensor uses an LED-based optical measurement method with forward light scattering. This enables the determination of turbidity caused by suspended particles in the water. Turbidity measurements provide useful additional information when assessing surface waters, wastewater and other water samples in which suspended solids may be present. Clear Measurement Display The control unit features a backlit monochrome graphic display on which the recorded measurement values are clearly presented. This facilitates the assessment of water quality directly at the measuring location. Data Storage and Transfer The instrument offers a storage capacity of up to 10,000 data sets. Stored measurement data can be transferred via the USB interface for further documentation and evaluation. Designed for Mobile Use The robust construction and water-protected components are designed for measurements under demanding operating conditions. The sensor probe complies with protection class IP68, while the control unit complies with protection class IP67 when the sensor cable is connected. Flexible Measurements with a 2-Metre Cable The 2-metre sensor cable allows the sensor probe to be positioned directly in the water while the operator controls the measurement from a nearby location. This configuration is particularly suitable for accessible sampling points, shallow water investigations and routine on-site measurements. Calibration and Sensor Maintenance The integrated calibration functions support the preparation of the measuring instrument for reliable measurements. Regular calibration, cleaning and maintenance of the sensors in accordance with the manufacturer's instructions are necessary to ensure consistently meaningful results.
