NEW! FMS-300 Pulse Amplitude Modulated (PAM) Fluorometer for teaching & research


A wide range of features and capabilities allow the FMS-300 to demonstrate complex concepts, conduct experiments, collect data, analyze results, and facilitate collaborative learning or research projects.

The FMS-300 is quick and easy to acquire and analyze data associated with pulse-modulated (PAM) and fast-fluorescence (OJIP) types of fluorometry. It is also a powerful research instrument offering data acquisition of exceptional quality.

  • Fast & slow fluorescence data for every saturating flash event

  • Exceptional signal quality

  • Multiple pre-set (but configurable) protocols for light- & dark-adapted kinetics

  • Measuring light & actinic/saturating LED color options
