AquaTracka III Fluorometer for in situ detection of Chlorophyll a, tracer dyes or turbidity

AquaTracka III Fluorometer (for Chlorophyll a, Rhodamine or Fluorescein monitoring) Chelsea Technologies Group’s AquaTracka III provides highly sensitive data on fluorescence parameters including Chlorophyll a, Rhodamine, Fluorescein or Turbidity, configured by factory-set fluorometer optics.

 

The AquaTracka III is available to output either an analogue logarithmic signal (4 decade) or alternatively, a digital signal which can either be RS232 or RS422. This flexibility of data output allows ease of integration to a variety of platforms including host CTD profilers, ROVs and towed vehicle systems. A flow‑through manifold is available to configure the AquaTracka III for in-line monitoring.

How does it work?

CTG’s AquaTracka III detects fluorescence. When dissolved compounds (that are of a fluorescent nature) absorb light they re-emit a fraction of this energy as fluorescence at longer wavelengths. Fluorescence intensity is directly proportional to concentration. The technique is widely recognised as one of the most sensitive detection methods available. A low power rugged pulsed xenon light source is used in conjunction with a virtually indestructible photodiode detector and a reference channel monitoring the intensity of each flash, providing excellent calibration stability over long time intervals.
