GFS-3000 Portable Gas Exchange Fluorescence System for the assessment of plant photosynthesis
GFS-3000
New
The GFS-3000 is a portable, high precision system for the assessment of plant photosynthesis (CO2-uptake) or respiration (CO2-release) and transpiration – in combination with optical measurements.

Gas exchange measurements rely on the basic principle that changes in CO2 and H2O concentrations are determined when air passes through a climate controlled chamber containing a plant sample.
The GFS-3000 is suitable for controlled laboratory settings as well as demanding field conditions.
The GFS-3000 perfectly complements with other Walz systems giving access to numerous aspects of photosynthesis research.
The Portable Gas-Exchange and Fluorescence System GFS-3000 enables wide range climate control. All environmental parameters relevant for plant photosynthesis (CO2, H2O, temperature, light, ventilation and flow) can be controlled automatically and over the full physiological range.
Optional fluorescence modules further expand the system’s capability. Experimental protocols for automatic light-curves or automatic CO2-curves can be easily programmed.
Main Components of the Basic System Package GFS-3000
• Control Unit 3200‐C containing the CO2 and H2O analyzer, as well as all components required for the CO2, H2O and flow control
• Standard Measuring Head 3010‐S featuring high application flexibility containing the ventilation system, temperature and light control
• LED Light Source 3041-L with warm white LED array providing up to 10 cm2 homogenous illumination
• AC Power Supply 3200‐N for laboratory use
• Four Li-ion eSMART Batteries 98 Wh for field work. Li-ion eSMART Quad Charger for simultanewour recharging of up to four eSMART batteries.
Modified System Package GFS-3000FL
The modified system package GFS‐3000FL contains the LEDArray/ PAM‐Fluorometer 3056‐FL instead of the LED Light Source 3041‐L. All other components remain the same as in the basic system package GFS‐3000. In terms of price, GFS‐3000FL offers an interesting option to combine gas exchange and fluorescence measurements.
Optional Components and Accessories
of the GFS-3000
• LED‐Array/PAM‐Fluorometer 3056‐FL for illumination of the leaf area and fluorescence measurements
• Fiberoptics PAM‐Fluorometer 3050‐F to analyze fluorescence in sunlight
• Miscellaneous accessories such as cuvettes and adapter plates offering user‐specific application options
• Accessories for product combinations with other Walz systems
Also, the complete equipment will be modified on customer request.
Control Unit 3200-C
Design: Aluminum housing featuring an integrated PC module, large graphical color-display well readable in sun-light with touch screen, 4-channel CO2/H2O gas analyzer, flow control, CO2 control (supplied via small cartridges or cylinders) and H2O control (for drying and humidifying). Pneumatic connectors for air inlet, measuring head and four vents. Sockets for cable connections: Cuvette: Standard Measuring Head 3010-S, DUAL-PAM Gas-Exchange Cuvette 3010-DUAL or Gas-Exchange Chamber 3010-GWK1; Aux in: two Auxiliaries; 3 Battery Slots: Li-Ion eSMART Batteries (each 14.4V/6.8Ah), Mains Power Supply Unit 3200-Nor 3200/BC adapter for 12 V or 24 V Battery; Comp (RS 485): additional component or 3010/I-Box for external PC control; 2 USB sockets (USB 2.0) to internal PC: USB storage device, other USB device or USB null modem cable (USB-NMC) for control by external PC via internal PC; Battery DC/in: two LiFePO4 Batteries 3035-A, AC Power Supply Unit 3020-N, or external DC (12-24 V)
CO2/H2O Gas Analyzer
Design: 4-channel CO2/H2O absolute NDIR gas analyzer, separate cuvettes for CO2 and H2O
CO2 measurement: Simultaneous absolute and differential measurements, absolute range: 0 to 5000 ppm, cuvette length 20 cm, cuvette volume of one cell 6 cm3, gas-filled detector
H2O measurement: Simultaneous absolute and differential measurements, absolute range: 0 to 75000 ppm, cuvette length 20 cm, cuvette volume of one cell 6 cm3, pyroelectric detector (solid state)
Max. noise in absolute mode: <0.2 ppm CO2 and <30 ppm H2O
Resolution: 0.01 ppm CO2, 1 ppm H2O
Linearization:
CO2 absolute: Max. error between 0 and 600 ppm: 12 ppm, between 600 and 3000 ppm: 2% of measured value
Deviation of differential CO2 zero with changing CO2: Typ. less than 0.5 ppm
H2O absolute: Max. error between 0 and 15000 ppm: 330 ppm, above 15000 ppm: 2% of measured value
Deviation of differential H2O zero with changing H2O: Typ. less than 150 ppm
Correction: Signal is corrected for temperature, pressure and H2O-effect on CO2 signal
Barometric air pressure measurement: Range 60 to 110 kPa, accuracy ±0.1%
