most of commercially available photosynthesis systems, the PM-48MB
Photosynthesis Monitor is specially designed for long-term monitoring of
CO2-exchange in several leaves simultaneously.
It is an open system with original leaf chambers. Due to
self-clamping design, the LC-4A leaf chambers do not disrupt the natural
conditions of the leaves under study. The LC-4A chamber fixes exposed leaf and keeps it open
between measurement cycles. The system operates with several chambers in
such a manner that they are sequentially closed for a few minutes and then
stay opened until the next measuring cycle starts.
Thus, the duration of
measurement is basically limited only by the natural aging of the leaf
under study, since the problem of leaf chamber effect is largely resolved
due to the LC-4A’s self-clamping design.
Data is collected in the datalogger's memory and can be transferred to PC
for further processing.
