branding of products, which many not be suitable for the application areas
(somewhat cynical and also will damage the reputation of the deployment of
sensors for marine applications).
• Have not had a chance to calibrate as yet.
• Not clear if wavelength of current sensors really match oil fluorescence well.
• Detecting different oil components (VIC, TPH) and phases (dispersed, dissolved).
• Some of the multi wavelength, combination sensors have inadequate dataloggers
and the software interface is very limited. The bio-wiper on these sensors are very
limited in functionality and the overall design is not robust.
Vendors:
• Interference from other fluorescent UV absorbing materials; Rated for 600
meters.
• There is no in field maintenance other than cleaning optical windows;
Instrument does not have any onboard telemetry;
No automatic calibration.
