PAM-2500

• Product of

  Walz GmbH

  The powerful chlorophyll fluorometer for field and laboratory studies.
  Das PAM-2500 fluorometer is a “high end” instrument from Heinz Walz GmbH that is characterised by high time resolution, extremely strong light pulses, different light sources and complete programmability. On the basis of its features, the instrument can be used both for studies on rapid fluorescence kinetics and for saturation pulse analysis. Its compact design makes the fluorometer mobile and therefore suitable for use in the field. In conjunction with a suitable light sensor (2030-B leaf clip accessory) it is possible to estimate the linear electron transport through photosystem II.
  The cast aluminium housing has connections for the fibre optics, communication cable, 2030-B leaf clip and battery charger or MINI-PAM/AK.
  The PAM-2500 operates with red modulated measuring light with maximum emission at 630 nm (alternatively: blue measuring light with maximum emission at 455 nm) with modulation frequencies of 10 to 200000 Hz and two photosynthetically active light sources: blue actinic light (maximum emission at 455 nm) with a maximum intensity of 800 µmol/m2s and red actinic light (maximum emission at 630 nm) with a maximum intensity of 4000 µmol/m2s. The red actinic light source is also used for saturation pulse and µ-second  bursts. There is additionally a far red light source with maximum emission at 740 nm. The fluorescence is measured using a photodiode. Optional accessories for the PAM-2500 also include the 2030-B leaf clip with micro quantum sensor to measure the photosynthetically active photon flux and Ni-CrNi thermocouple  to determine leaf temperature, a cuvette and agitator to measure suspensions and dark leaf clips to determine Fm and F0 in daylight. There is furthermore an ultra-mobile computer (Samsung Q1) which fits in the bag supplied with delivery of the PAM-2500.
