1.      Tính năng kỹ thuật:

Overview:

-          Water is as precious as life itself. That's why current threats to water supplies make water quality analysis vital to our very existence. HORIBA has created the Multifunction Water Quality Monitoring System. Years of HORIBA sensor technology development have reached their culmination in the form of a 46-mm diameter sensor probe: a compact monitoring solution offering high pressure tolerance, long-term continuous measurement capability and highly accurate, simultaneous analysis of 13 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.

Features:

-          Up to one month Data logging: The sensor's built-in memory function enables continuous measurement for as long as one month*––– just by leaving the probe submerged in the sample. Personnel need not to be present during the measurement process––– the data can even be captured by personal computers in remote locations. (*With measurements every 15 minutes)

-          Measurement at depths as low as 100 meters: With its superior durability and high pressure resistance, the newly developed sensor facilitates measurements as far as 100 meters below the water surface. Thus, in addition to rivers, lakes and other shallow bodies, high-precision measurement can now be readily obtained ––– and water quality can be monitored ––– at dams, and even in the open sea.

-          Simultaneous measurement of 13 parameters: With the W-23XD unit (only), simultaneous measurements of up to 13 parameters (from pH, dissolved oxygen, and conductivity to seawater specific gravity and a variety of ions) can be obtained ––– much more quickly and easily than with conventional instruments. With its powerful measurement capabilities.

-          System enables GPS and numerous other data processing mechanisms: System capabilities can be greatly increased by installing the Global Positioning System (GPS), supplied with unit U-2002. GPS allows measurement of location and time, in addition to water quality, and enables main unit screen display of the obtained data ––– an indispensable function for maintaining detailed records. With the acquired longitude, latitude and depth data, subject locations can be mapped in 3-D.
