Field-swappable battery system for FMS 2 Pulse-Modulated Chlorophyll Fluorescence Monitoring System | Hansatech Instruments | Oxygen electrode and chlorophyll fluorescence measurement systems for cellular respiration and photosynthesis research

The FMS 2+ chlorophyll fluorimeter is powered by a 2.0 Ahr lead-acid battery, capable of >5 hours of continuous actinic illumination of 3,500 µmol m-s s-1 or of delivering approximately 4,000 saturating pulses of 13,000 µmol m-2 s-1 at the sample surface.

Up to four batteries may be charged in the FMS 2+ multi-charger overnight and easily exchanged in the field as they become discharged.

5 batteries are supplied with the FMS 2+ which, when all fully charged, easily provide several full days measurement in the field. The FMS 2+ carrying bag has space in the bottom to carry one spare battery.
