Chelsea announces unprecedented interest in the new FASTtracka II Fluorimeter

Chelsea Technologies Group Ltd is pleased to announce that the new FASTtracka II Fast Repetition Rate Fluorimeter is now in full production. Several instruments have been delivered to major domestic and foreign laboratories, including existing FASTtracka Mark I customers.

The launch of the new instrument has seen unprecedented interest from both the traditional oceanographic community and fresh water monitoring groups.

The FASTtracka II offers significant improvements in performance to its predecessor, with increased sensitivity and high ambient light rejection. Beyond this, the FASTtracka II also offers additional functionality, now providing Multiple Turnover (MT) as well as Single Turnover (ST) modes. Users also now have complete control of excitation protocols, and can define variable flashlet duration and intervals. With these improvements, Chelsea has launched the new instrument at a price significantly lower than its predecessor.

The FASTtracka II is fast becoming a key tool for monitoring photosynthetic performance in phytoplankton, within primary production studies, bloom detection and toxicity monitoring. As the FASTtracka II acquires data extremely rapidly (typically 200 ìs in ST mode), the instrument lends itself to operation in many platforms including towed vehicles, fast profilers, AUVs and Gliders.
