Hansatech FMS 2
Hansatech FMS 2

Product Features
  • FMS 2 is a lightweight, field portable fluorescence instrument which uses the pulse-modulated principle to monitor chlorophyll fluorescence.
  • It is therefore suitable for non-intrusive sampling from tissue operating under natural light or working in conjunction with other techniques such as infra-red gas analysis (IRGA).
  • 594 nm amber modulating beam
  • Optional 470 nm blue LED
  • Dual-purpose halogen actinic- 0 to 3,000 µmolm-2s-1 in 50 steps.
  • Saturating pulse lamp --0 to 20,000 µmolm-2s-1 in 100 steps.
  • 735 nm far-red LED source for preferential PSI excitation.
