HORIBA U-50 Series Multiparameter Water Quality Meter

from $4,060.00
Select Configuration:

BRAND: HORIBA

The HORIBA U-50 Series is a portable multiparameter water quality meter designed for groundwater, surface water, wastewater and environmental field monitoring. A single submersible probe measures multiple parameters simultaneously, including pH, ORP, dissolved oxygen, conductivity, salinity, total dissolved solids and temperature. Select models add turbidity, water depth and GPS capabilities.

Available configurations include the U-51, U-52, U-52G, U-53 and U-53G with 2, 10 or 30-meter cables. AWM Instruments can help you select the appropriate model, cable length, accessories and calibration supplies.

Field-Ready Features & Benefits

  • One-touch automatic calibration: Simplifies calibration of pH, dissolved oxygen, conductivity, turbidity, and water-depth measurements.

  • Field-ready construction: A shock-resistant protective cover helps withstand demanding field conditions and is easy to clean after use.

  • Quick-connect probe cable: Connect or disconnect the sensor cable quickly for easier setup, transportation, and storage.

  • Auto Hold function: Automatically displays a stabilized average reading, giving the operator time to review or record measurement results.

  • Built-in diagnostics: Alerts the operator to instrument errors and helps identify when sensor inspection or replacement may be required.

  • USB data transfer: Transfer stored measurements to a computer for analysis, reporting, and recordkeeping. The USB cable and data-management software are available separately.

  • Selectable measurement units: Display results in the preferred units without performing manual conversions.

  • Onboard data logging: Store up to 10,000 measurement sets in the handheld control unit for later retrieval.

  • Clear field display: A backlit LCD presents multiple water-quality parameters simultaneously for convenient field review.

Which HORIBA U-50 Model Should I Select?

Choose a model based on the required turbidity method and whether water-depth or GPS data must be recorded with each measurement.

U-51

Core Water-Quality Parameters

Choose the U-51 when your program requires pH, ORP, dissolved oxygen, conductivity, salinity, TDS and temperature without turbidity or depth measurement.

U-52 / U-52G

General Field Turbidity

Choose the U-52 for general turbidity monitoring. Select the U-52G when GPS and water-depth measurements are also required.

U-53 / U-53G

US EPA Method 180.1

Choose the U-53 for US EPA Method 180.1 turbidity, an integrated turbidity wiper and water-depth measurement. The U-53G adds GPS.

U-54 / U-54G

EN ISO 7027 Turbidity

Choose the U-54 for infrared LED turbidity measurement conforming to EN ISO 7027. The U-54G adds GPS. Depth is available on 10 m and 30 m configurations.
