Testing of ground and surface water is a key part of routine testing for water companies. Depending on the need, a number of different parameters are often assessed. The Horiba LAQUA range has a meter specifically designed for this type of analysis.

The U-50 series of multi-parameter meters enables the simultaneous measurement and monitoring of up to 11 parameters with one unit, these include:
- pH and pH(mv)
- Oxygen-Reduction Potential (ORP)
- Dissolve Oxygen
- Conductivity (CON)
- Salinity
- Total Dissolved Solids (TDS)
- Seawater-Specific Gravity
- Temperature
- Turbidity
- Water Depth
- Global Positioning System (GPS)

This unit has been designed with field use in mind. The meter has IP67 rating with shock & scratch-resistant housing for the digital sensors ideal for on-site monitoring of river, groundwater, drainage water. In addition, the user interface allows simultaneous readings of multiple paraments, easing monitoring.
Below are the variations in the series, which will assist in determining the best one for your needs.
