MultispeQ v2.0


The MultispeQ combines the functionality of a handheld fluorometer, a chlorophyll meter, and a bench-top spectrometer into one low cost, modifiable tool that brings lab quality measurements to field applications. Measure photosynthetic phenotypes in real field conditions, identify biotic and abiotic stresses in plants or algae, and collect thousands of data points around the world using collaborators in the PhotosynQ network. The MultispeQ is what you wanted all your other tools to be - affordable, powerful, modifiable, and collaborative by design.
