JUNIOR-PAM

• Product of

  Walz GmbH

  The JUNIOR-PAM is the chlorophyll fluorometer used in teaching. The inexpensive instrument for teaching in schools and universities can be operated using just a notebook. The device measures pulse amplitude modulated (PAM) chlorophyll fluorescence which makes it possible to examine photosynthesis under natural light conditions. Using the “saturation pulse analysis” it is easy to establish the photosystem II efficiency. The measurements permit statements to be made on the stress and damage conditions of plants. By way of standard the device is operated with the JUNIOR-B leaf clip which measures the light intensity at leaf height and the leaf temperature. The aluminium housing has a socket for a USB cable and for the JUNIOR-B leaf clip. The control and power supply are via the USB cable type A-B.
  The internal light source generates blue modulated excitation light with maximum emission at 465 nm and two modulation frequencies (5 and 100 Hz) or blue actinic light with a maximum photon flux density of 1500 µmol/m2s; the maximum intensity of the saturation pulse is 10000 µmol/m2s. A dark red light source is available for selective excitation of photo-system I. The fluorescence is detected using a PIN-photodiode.
  Optional accessories include the “Monitoring Leaf-Clip JUNIOR-B” with micro quantum sensor for selective measurement of the  photosynthetically active photon flux density and Ni-CrNi thermocouple temperature measurement.
