Chlorophyll fluorometer DIVING-PAM-II

The launch of the DIVING-PAM underwater fluorometer started the era of PAM fluorescence analysis of photosynthetic organisms in their natural habitat. The second-generation underwater fluorometer, the DIVING-PAM-II, extents this era with the latest technology. The DIVING-PAM-II exclusively uses LEDs as internal light sources, which permits exact timing of switching processes, and prevents overheating by continuous illumination. A built-in PAR sensor continuously records the intensity of internal light. An energy-efficient B/W screen shows data and settings numerically and graphically. The DIVING-PAM-II system includes a Miniature Spectrometer MINI-SPEC to measures spectra of PAR, which vary significantly with water depth. The total external PAR is automatically calculated. The spectrometer also permits spectral analyses of the sample’s fluorescence emission and reflectance. Outstanding Properties of the DIVING-PAM-II •System package with underwater spectrometer •Operating range up to 50 m diving depth •Internal PAR sensor •Red or blue plus far-red light
