Horiba U-22 Water Quality Instrument Rental

  • Measures pH, conductivity, dissolved oxygen (DO), oxidation reduction potential (ORP), turbidity, temperature, salinity, total dissolved solids (TDS), and seawater specific gravity.
  • Slim design allows it to fit into 2" wells and larger.
  • Optional flow-through cell available for low flow sampling measurements.

We no longer offer this product. If available, suggested replacements will be listed below.

Years of Horiba sensor technology development have reached their culmination in the form of a 46-mm diameter sensor probe. These units offer a compact, highly accurate monitoring solution with high pressure tolerance, long term continuous measurement capabilities, waterproof construction, and monitoring of up to 10 parameters. The Horiba U-22 has Flow Cell capability making it perfect for low flow sampling events.
