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.

General Features DIVING-PAM-II

The cylinder-shaped DIVING-PAM-II fluorometer is approved for water depth down to 50 m. Advanced sensors record pressure and temperature. A high power LED is used for actinic light and saturation pulses. A far red LED for specific PS I excitation is installed. A proven fiberoptics connects sample and DIVING-PAM-II. All relevant parameters of saturation pulse analysis are automatically calculated.
