Years of Horiba sensor technology development have reached their culmination in the form of a 47-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. In addition to the Water Quality Monitoring System's own capabilities, it was designed by Horiba to be compatible with GPS and other data processing techniques.  And now, the W-22 is available with a flow through cell designed by Horiba.

Simultaneous Measurement of up to 10 Parameters

pH, Dissolved Oxygen, Conductivity, Salinity, Total Dissolved Solids, Sea water Specific Gravity, Temperature, Turbidity, Depth, Oxygen Reduction Potential

The NEW W-22XD (Extra Durable) design

Includes a new 316 Stainless Steel Probe Cover, Stronger CT cell, and Pelican carrying case.

One Touch Calibration

Just submerge the probe into the calibration beaker filled with standard solution and press the button for simultaneous one-point calibration.  The system also enables two-point calibration where high precision measurement data is required.

Probe assembly fits inside 2-inch well

Data Logging Capability

The sensor's built in memory function enables continuous measurement for as long as one month (with measurements every 15 minutes).

Measurement at Depths up to 100 Meters

High-Precision Dissolved Oxygen Sensor

This quick response sensor requires no stirring.

System Enables GPS, PC, and Printer Capabilities

Dry Cell Battery Operated

Runs on standard alkaline batteries.
