What is C-FLUOR?
C-FLUOR Submersible Probes are sensitive, extremely low power, single wavelength in situ fluorescence and turbidity sensors available in several optical configurations. Requiring a maximum of 12mA current at 12VDC input, C-FLUOR probes can be integrated and deployed for much longer intervals than previously possible with submersible probes. And, with a very fast response time of less than 0.6 seconds, they require even less power, outputting data soon after power is applied.

HAB Monitoring Made Easy - Tech Talk
Innovative instrumentation is available for developing new age methods of monitoring for algae. Advancements in optics and electronics allow us to build specialized fluorometers that target specific marker pigments in an effort to more accurately quantify various algal groups or estimate pigment concentrations in real-time, in the field. The traditional methods of collecting grab samples from the field for processing can now take a back seat to the better resolved data sets we can compile from these new age tools.
