HORIBA U-50 Series

Multi-parameter Water Quality Checker

Portable multiparameter water quality measurement

HORIBA U-50 series Multi-parameter Water Quality Meter enables you to measure up to 11 parameters simultaneously with a single submersible probe. The rugged design enables user-friendly on-site monitoring for rivers, creeks, ponds, ground water, drainage water, etc. Function and performance are optimised with this easy to use yet powerful water quality monitoring equipment.

Supplied complete with backpack carry bag and all sensors (depending on model).

Control Unit Design for Field Operations

  • Auto-calibration feature provides hassle free calibration of pH, dissolved oxygen, conductivity, turbidity, and depth.
  • Shock resistant cover designed for rough treatment in the field and is easily cleaned.
  • Cable can be easily connected and disconnected with quick-connect fitting.

Data Management

  • Auto hold function freezes average data values on the screen to offer more time to verify or transcribe data.
  • Diagnostic functions notify the user of errors.
  • Integral USB connection for data transfer to a PC. The USB download cable is sold separately and includes software.
  • Selectable measurement units allow the operator to report data without the need to convert data to desired units of measure.

Multiple Sensors Housed in Each Probe

  • Multiple sensors allow for the measurement of up to 11 parameters simultaneously (pH, pH(mv), ORP, DO, COND, Salinity, TDS, Seawater Specific Gravity, Temperature, Turbidity, Water Depth), depending on which model is used.
  • Turbidity sensor U-53 conforms to US EPA method 180.1. Precision has been improved over conventional instruments. The U-53 model has a high precision field replaceable turbidity sensor with wiper and is suitable for applications where high resolution of 0.01 NTU is required.
  • The standard turbidity sensor on models U-52 and U-52G offers turbidity measurement with resolution to 0.1NTU which is excellent for environmental monitoring
  • Improved stability of the dissolved oxygen sensor has been achieved with a new 3 electrode design for fast response and polarographic sensor for ease of maintenance.
  • pH glass electrode, pH reference electrode and ORP electrode can be replaced individually to reduce replacement costs
