Horiba W-20XD Series

Multiparameter Water Quality System

Horiba’s W-20XD series water quality monitoring system features advanced sensors which support continuous monitoring while offering high precision and simultaneous measurement of up to 13 parameters. Includes W-22XD and W-23XD.

Horiba’s W-20XD series water quality monitoring system features advanced high-precision sensors which are ideal for use in pressurized conditions. W-20XD supports simultaneous measurements of as many as 13 parameters, including pH (option), DO (option), conductivity, salinity, TDS, seawater specific gravity, temperature, turbidity, depth, and ORP (option). The W-20XD series includes the W-22XD and the W-23XD which supports optional ion sensors and is capable of measurement at depths up to 100 meters.

The W-20XD system is optimal for measuring water quality in a wide range of saltwater or freshwater applications. Sensor electronics are housed in a 47 mm probe and are suitable for operation in pressurized conditions. It is compatible with GPS and data retrieval options for easy data management on a PC. Parameter range, resolution, and accuracy information is included in the specifications sheet.

W-20XD probes have enough memory to store data from up to one month of continuous monitoring at 15 minute intervals. Because memory is stored in the sensor probe, it can be deployed without cables and the control unit for independent monitoring. The W-22XD sensor probe includes a depth sensor, conductivity-temperature-turbidity sensors, and optional replaceable DO and pH/ORP sensors. The W-23XD sensor probe includes a depth sensor, conductivity-temperature-turbidity sensors, optional replaceable DO and pH/ORP sensors, and support for replaceable ion sensors. Optional sensors for use with the W-23XD include nitrate ion, calcium ion, fluoride ion, potassium ion, and ammonia. Cables are available in 2, 10, 30, 60, and 100 meters. Additional probes for other applications are available. A W-20XD system includes a control unit, any desired probes, and cable.

The W-20XD series includes the W-22XD and the W-23XD.
