The chlorophyll fluorometer MONITORING-PAM is designed for long-term monitoring of chlorophyll fluorescence even under harsh weather conditions. Compact and robust emitter-detector units measure modulated chlorophyll fluorescence and perform saturation pulse analysis.
Up to seven sites per MONITORING-PAM can be measured simultaneously. At each site, photosynthetically active radiation (PAR) at sample level is measured so that relative electron transport rates can be derived from PAR data and photochemical yields of photosystem II.
