What is LabSTAF?

LabSTAF active fluorometer

LabSTAF active fluorometer by Chelsea Technologies
  • Monitoring phytoplankton primary productivity using the latest in STAF technology

  • Unparalleled sensitivity allowing measurements in extreme oligotrophic waters
  • Wide dynamic range providing reliable measurements from open ocean, coastal waters and lakes
  • Fully automated acquisition allows for continuous measurements without manual intervention
  • Compact and robust portable unit – ideal for deployment on research vessels and outdoor locations
  • Automated sample exchange and system cleaning for extended autonomous operation


Why LabSTAF?

  • Advanced corrections as standard
  • Seven waveband excitation for spectral correction of photosynthetic measurements and assessment of community structure
  • Dual fluorescence waveband measurement to compensate for the reabsorption of chlorophyll fluorescence through the package effect
  • Baseline subtraction to exclude fluorescence signal from non-photosynthetic sources


VLux AlgaePro

VLux AlgaePro is the latest advancement in in situ fluorometers from Chelsea Technologies, measuring 4 algal groups with integrated environmental corrections for absorbance and turbidity in one compact sensor. The absorbance measurements also provide a correction for CDOM interference and increase dynamic range by a factor of 20x.

PAR Sensor

Gather highly sensitive data on light irradiance with the Chelsea PAR sensor. With a depth rating of 1000 m, the PAR sensor can be fitted to profiling systems or oceanographic moorings to get a complete picture of the photic zone. The long term calibration stability and titanium corrosion-resistant housing make it ideal for long term deployments on vehicles or wider instrumentation systems in all water environments.
