V-Lux: Multi-parameter fluorometer configured to detect either Algae, Aromatic Hydrocarbons or Tryptophan-like fluorescence
Chelsea Technologies Group’s V-Lux is a miniature multi-parameter fluorometer configured to provide high quality in situ detection of either Algae, Aromatic Hydrocarbons or Tryptophan-like fluorescence. Fluorescence is automatically corrected for turbidity, absorbance and temperature to provide robust data collection over extended deployments.
Monitoring Applications:
- Environmental pollution
- Algal monitoring
- Sewage and bathing waters
- Oil spill including road and airport apron run-off
- Point source pollution
- Biological Oxygen Demand (BOD) indication
- Coloured Dissolved Organic Matter (CDOM)
- Exhaust gas scrubber wash water
