Heinz Walz GmbH has been serving science for more than 40 years with sophisticated measuring devices for plant research. Technical progress in LED technology and other electronic components allows us to design instruments with unprecedented analytical potential. These novel devices again drive progress in science.
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.
High-performance Field and Laboratory Chlorophyll Fluorometer.Major Points of the PAM-2500: Saturation pulse as well as polyphasic rise analysis with time resolution down to 10 μs Latest generation light-emitting diodes for all internal light sources High sensitivity enabling high quality measurements with dilute suspensions of algae and cyanobacteria.
