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 location with measurements every 15 minutes.

Simultaneous measurements of up to 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 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.
