Horiba W-21SDI Water Quality Monitoring System

Horiba W-21SDI can now interface with SDI-12 compatible data collection platforms and integrate into third party monitoring systems.

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 8 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 U-20 series is available with a detachable cable and flow through cell designed by Horiba. 

Features:

• The NEW U-20 series design W-21SDI - 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).

• Simultaneous Measurement of up to 8 Parameters

• Measurement at Depths up to 60 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.
