MODULAR Version

DUAL-PAM-100

The MODULAR version of the DUAL-PAM-100 measuring system consists of the Power-and- Control-Unit DUAL-C which can be combined with various emitter and detector heads. Due to various novel opto-electronic components, specially developed for the DUAL-PAM-100 measuring system, all emitter and detector units are very compact and easy to handle.

Modularity permits to choose between blue or red modulated excitation of chlorophyll fluorescence. Also, for measurements requiring high measuring sensitivity, the Photodiode Detector DUAL-DPD and the more sensitive Photomultiplier Detector DUAL-DPM can replace the standard measuring heads.

Generally, the MODULAR version provides a very flexible design of the measurement setup depending on the scientific question posed. The subsequent table compiles a number of typical measurement setup of the DUAL-PAM-100.
