Horiba U-22 Water Quality Instrument Rental
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.
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.
