For Long-term Monitoring of Photosynthesis

The chlorophyll fluorometer MONITORING-PAM is designed for unattended, long-term and multi-site monitoring of chlorophyll fluorescence in air or underwater. At each measuring site, compact and robust emitter-detector units measure modulated chlorophyll fluorescence and perform saturation pulse analysis.

Depending on system configuration, up to seven sites per MONITORING-PAM system can be measured simultaneously. At each site, photosynthetically active radiation (PAR) at sample level is recorded so that relative electron transport rates can be derived from PAR data and photochemical yields of photosystem II.
