The GFS-3000 is a WALZ portable gas-exchange and fluorescence system designed for advanced photosynthesis research. It quantifies CO₂ and H₂O changes in controlled air streams across a measuring chamber containing plant tissue, enabling accurate assessment of assimilation, transpiration and physiological performance.

The platform provides automatic control of key environmental variables (CO₂, humidity, temperature, light and flow), allowing highly reproducible protocols in laboratories and demanding field environments. It can be used as a pure gas-exchange setup or combined with PAM fluorescence modules.

GFS-3000 base package:

3200-C control unit with integrated CO₂/H₂O NDIR analyzer and CO₂, H₂O and flow regulation.
3010-S measuring head with clamp cuvette, temperature and light control.
3041-L LED light source for homogeneous chamber illumination.
3200-N AC power supply for lab use.
Li-ion battery system and charger for extended portable operation.

Configurations and expansion:

GFS-3000FL configuration with 3057-FL for advanced fluorescence workflows.
Compatibility with 3050-F fiber-optics fluorometer.
Cuvettes, adapter plates and user-specific accessory setups.
