JUNIOR-PAM

Teaching Chlorophyll Fluorometer

Pulse-amplitude modulated (PAM) chlorophyll fluorometry in combination with saturating pulse analysis of fluorescence quenching is now a standard technique to assess plant photosynthesis.

In the 1990s, the Walz Teaching-PAM fluorometer (PAM-200) carried PAM fluorometry into university classrooms. Since then, there has been considerable progress in LED and PC technology, enabling the development of a powerful and versatile, and at the same time compact teaching fluorometer: the JUNIOR-PAM.

Peculiar Properties

The JUNIOR-PAM features the smallest size and best price-performance ratio of all PAM fluorometers. It excels by its simplicity and ease of operation.

The JUNIOR-PAM is controlled by PC via USB interface: the fluorometer does not require a separate power supply as it is powered by the PC via the USB line.


The same WinControl-3 software is provided as for research PAM fluorometers like the MONITORING-PAM. In addition, WinControl-3 can be operated in a simplified mode to assist teaching in elementary courses.

The JUNIOR-PAM is particularly well suited for teaching classes and workshops, where availability of a larger number of instruments is essential for gaining hands-on experience.
