Accurate data, unattended
WET Labs and Sea-Bird Electronics have teamed to bring offshore research-grade measurement technology to inshore and estuarine research and ocean observing applications.

The WQM's sensors have the accuracy and precision to track subtle long-term changes in clean ocean environments. By combining multiple active and passive anti-fouling features, the WQM assures this data quality in coastal and inshore regimes. Extensively tested, field trials have demonstrated the WQM's unprecedented long-term stability in biologically rich coastal waters

Built for extended deployment
Biofouling and sediment loads are the dominant factors that degrade and limit the data quality from the WQM's sensors, not their inherent stability. These factors can overwhelm inadequately protected sensors and invalidate their data—often in just a few days. The WQM employs active flow control, passive flow prevention, light-blocking, active biocide injection and passive inhibitors to effectively and safely combat internal and external fouling. With fouling minimized, the superior inherent stability of the WQM sensors translates directly to superior long-term data quality.

Cost effective—now and later
The cost of monitoring is tied to the instrument life cycle and real value is ultimately provided only through quality data, day after day, month after month, year after year. The WQM provides quality data while dramatically reducing the need for field and factory service. The bottom line: the WQM delivers unequalled long-term data quality and minimizes operational and maintenance costs.
