Sea-Bird Scientific WQM
Water Quality Monitor for Maximum Deployment Times
Ideally suited for unattended monitoring the WQM X 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.
- Unattended
- Conductivity, pressure, chlorophyll, temperature, dissolved oxygen, turbidity
- Designed specifically for extended deployment in biologically rich waters
- RS-232
- Robust: excellent anti-fouling capability provided by EPA approved anti-foulant, internal, pumped flow path and external copper cladding and wiper
- Accurate: high initial accuracy and low drift rate
- Cost Effective: typical deployment duration of 3- 6 months equals fewer site visits and lower operational costs year after year
- External port enables the easy integration of an additional sensor
