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.

Simultaneous Measurement of up to 13 Parameters

pH, Dissolved Oxygen, Conductivity, Salinity, Total Dissolved Solids, Sea water Specific Gravity, Temperature, Turbidity, Depth, Oxygen Reduction Potential, and a variety of ions (Nitric Acid, Chloride, Calcium, Fluoride, Potassium, and Ammonia)

The NEW W-23XD (Extra Durable) design

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.

Data Logging Capability

The sensor's built in memory function enables continuous measurement for as long as one month (with measurements every 15 minutes).

Measurement at Depths up to 100 Meters

High-Precision Dissolved Oxygen Sensor

With its membrane galvanic cell, the HORIBA dissolved oxygen sensor is virtually impervious to eddies and flows in the solution. Highly precise measurements can now be obtained with an ease.

System Enables GPS, PC, and Printer Capabilities

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.

Dry Cell Battery Operated

Runs on standard alkaline batteries.
