Classic Submersible Fluorometer
Aquation’s Classic Submersible Fluorometer combines the simplicity of the Classic Fluorescence Sensor with the utility and rugged design of the Submersible Datalogger. The Classic Submersible Fluorometer measures the effective quantum yield of PSII energy conversion, and can provide actinic light treatments such as Rapid Light Curves or other light treatments at any time of the day or night. Up to three Classic Submersible Fluorescence sensors can be easily operated automatically from one Submersible Datalogger. Optical signals are transmitted to and from the sample and sensor via a light pipe. The sample is held in a fixed position with respect to the light pipe with a sample holder. Use of this light pipe assembly ensures the sample is not shaded by the Classic Fluorescence Sensor.
This system has already beeen sucessfully used in seagrass studies in both Sydney Harbour and Corsica. A primary advantage of this system is the ability to take continuous measurements of the same sample over a 24 hour period. This provides pre-dawn values of Fo and Fm, enabling one to easily calculate photochemical and nonphotochemical quenching parameters (qP and qN). The Far Red Light option is also available, and can be used at any time to determine Fo’.
