FMS 2 Chlorophyll Fluorimeter

Soil & CropsPhotosynthesis Chlorophyll & Respiration

The FMS 2+ chlorophyll fluorimeter consists of a control unit housing all of the electronics, optics and light sources necessary to derive most common chlorophyll fluorescence parameters. These are optically linked to the sample by a statistically randomised fibre-optic cable that is positioned in the FMS/PTL PAR/temperature leafclip. The fibre-optic cable is also suitable for insertion into a range of sample containers such as oxygen electrode chambers, older gas-analysis chambers, petri dishes and microtitre plates.
