Rentals, Sales, & Service

Environmental Equipment & Supply is your source for sales and rentals of the entire Horiba U-50 series of water quality meters. Featuring a 2, 10 or 30 meter fixed cable for easy field deployment, U-50 water quality meters give you fast and accurate readings of a number of useful parameters.


Horiba U-50 series water quality meters provide simultaneous measurements of up to 11 parameters. All units come equipped with the following sensors: pH, ORP, dissolved oxygen, conductivity, salinity, total dissolved solids (TDS), seawater specific gravity and temperature.

  • U-51: The U-51 is the most basic configuration of the Horiba U-50 series. It includes all the sensors listed above. The U-51 is available in 2 and 10 meter cable lengths only.
  • U-52 and 52G: The Horiba U-52 is the next step up from the base model, adding turbidity sensing using LED 30° scattering. The U-52 can be outfitted with an optional GPS unit (U-52G) for geotagging log data. Upgrading to the GPS-enabled unit also adds the capacity to take depth measurements accurate to ±0.3m. THE U-52 IS OUR MOST POPULAR METER.
  • U-53 and 53G: The U-53 improves on the Horiba U-52's turbidity measurement capabilities with an upgrade to a tungsten 90° scattering sensor. The U-53 is also available with GPS; both the GPS- and non-GPS-enabled models can provide depth readings.
  • U-54 and 54G: The U-54 features the most advanced turbidity sensor available, using LED 90° scattering to deliver unparalleled accuracy even in the most demanding field conditions. Like the Horiba U-52 and 53, the U-54 is available with a GPS, as well.
