OS1p

Ultra Compact Chlorophyll Fluorometer

Chlorophyll fluorescence can be used to measure most types of plant stress. The OS1p offers a number of fast tests including Quantum Photosynthetic Yield, Fv/Fm, Quenching relaxation and Rapid light curves to analyse these stresses. Multiflash tests can be performed at high saturation light levels.
