HORIBA sensor technology development have reached their culmination

HORIBA has designed the Multl-Parameter Water Quality Monitoring Meter to be extra durable with the convenience of the auto-calibration feature. Years of HORIBA sensor technology development have reached their culmination in the form of a single 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 PC.

  • Up to one month Data logging
    The sensor's built-in memory function enables continuous measurement for as long as one month*. Measurement data is stored in the probe therefore the probe only can be deployed at the site on a line.  Data can even be captured by personal computers in remote locations. Data storage capacity: 2880 sets.
    *With measurements every 15 minutes, shorter data collection frequencies exhaust the battery life faster.
  • Measurement at depths to 100 meters
    With its durability and capability to operate at a high pressure , the sensor enables the user to take measurements as far as 100 meters below the water surface. In addition to rivers, lakes and other shallow bodies, high-precision measurements can be readily obtained from dams and the open sea.
  • Simultaneous measurement of 13 parameters
    With the W-23XD unit (only), simultaneous measurements of up to 13 parameters to include ion measurements.  With the W-22XD, 10 parameters can be measured at one time.
  • System enables GPS and PC connectivity
    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. With the acquired longitude, latitude and depth data, subject locations can be mapped in 3-D.
