The PAM fluorometry with the saturation pulse method provides detailed information on the light-energy usage of photosystem II and, thus, adds important information on primary photosynthetic reactions to the gas exchange data.
The LED-Array/ PAM-Fluorometer 3055-FL collects the fluorescence information with 6 detectors on up to 8 cm2 sample area. Therefore it allows gas exchange measurements with the complete sample area of the Standard Measuring Head 3010-S.
Its LED array provides actinic red and blue light as well as the saturating light pulses. Also, it features far-red LEDs to determine the Fo’ fluorescence. It connects with a simple snap-on mount to the Standard Measuring Head 3010-S, allowing optical control when positioning the leaf in the cuvette.
For the determination of the maximum fluorescence signal (Fm), the leaf needs to be dark acclimated. The additional light-weight Dark Leaf Clips 3010-DLC, with positioning aid and sliding shutters, made from sun reflecting material, fit to the measuring area of the 3010-S.
The system package GFS-3000FL contains the same components as the system package GFS-3000, except that it includes the LED-Array/PAM-Fluorometer 3055-FL instead of the LED Light Source 3040-L.
