Surface Water & Groundwater

Hydrolab multiparameter sondes can measure a wide variety of water quality parameters via spot sampling or unattended, real-time data capture in surface water and groundwater applications, providing the flexibility to tailor sensors to the exact application need. 

Hydrolab Multiparameter Sondes:


Long Term Deployment

Sea-Bird Scientific sensors are designed for long term deployments of up to 12 months. The portfolio of monitoring solutions includes instruments for multi-parameter monitoring in the most challenging environments on earth.

Sea-Bird Scientific WQM (Water Quality Monitor) and Sea-Bird Scientific HydroCAT EP:

  • Robust designs made specifically for long term deployments in biologically rich waters
  • Anti-fouling solutions for optimized unattended monitoring
  • High accuracy instruments proven to last up to 12 months, depending on the application and aquatic conditions 


Nutrient Monitoring

Continuous monitoring of nutrient levels in water bodies provides critical information about the daily, seasonal and event based changes in water quality conditions. Nutrient levels also are key indicators on the overall health of the water body.  In recent years, monitoring nutrient levels has become standard in regulatory compliance of water quality in many regions of the world. Sea-Bird Scientific provides several solutions for long-term unattended measurement of nitrate and phosphate in real-time.

Sea-Bird Scientific SUNA: Optical Nitrate Sensor:

  • Optical measurement of nitrate for high accuracy and no need for reagents
  • Measures nitrate in increasingly challenging waters, including extremely turbid and high CDOM waters.
  • Stability over a wide range of environmental conditions, from blue-ocean nitraclines to storm runoff in rivers and streams.

Sea-Bird Scientific Cycle-P: Phosphate Sensor:

  • Provides unparalleled precision and accuracy in phosphate nutrient monitoring
  • Ideally suited for unattended monitoring the Cycle PO4 includes pre-mixed on-board reagent cartridges and on-board calibration standards
