Horiba U-20 Series Water Quality Monitoring System

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 13 parameters.

Features:

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. (10m and 30m cable units only)
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 10 Parameters
Measurement at Depths up to 30 Meters
High-Precision Dissolved Oxygen Sensor - This quick response sensor requires no stirring.
System Enables PC, and Printer Capabilities
Dry Cell Battery Operated - runs on standard alkaline batteries.

Notes: The accuracy rating value is obtained from measurements at an intermediate point of the standard solution after two-point calibration (at room temperature andpressure). The repeatability and accuracy rating percentages are based on the full scale (except for salinity).

Organic solvents, strong acids, and strong alkaline solvents cannot be measured.
The accuracy rating is obtained from measurements at an intermediate point of the standard solution after two-point calibration (at room temperature and pressure).
The repeatability and accuracy rating percentages are based on the full scale (except for salinity).
Datalogging capabilities are based on data measured automatically at 15 minutes intervals with new alkaline batteries.
Periodical electrode maintenance and multi-point calibration is necessary.
