Contains the CO2 and H2O infrared gas analyzers (IRGA), flow control, and computer system. Standard Measuring Cuvette (3010-S):
: The actual leaf clamp cuvette. It features leaf temperature thermocouples, dual Photosynthetically Active Radiation (PAR) sensors, and an internal ventilation impeller.
The official user manual covers:
Download both the "Operation Manual" and the "Short Instructions." The short instructions are laminated and weatherproof—ideal for field use. The full manual should remain on your office computer for deep study. concentrations in a closed or open loop system
Calculated based on the difference between reference and sample gas streams. Stomatal Conductance ( ): A measure of leaf water loss.
: The clamp-style cuvette (standard volume of 40 ml) encloses plant tissue up to 8 cm2c m squared
Unlike a standard kitchen appliance, the GFS-3000 integrates gas exchange measurement (CO2 and H2O) with a pulse-amplitude-modulated (PAM) chlorophyll fluorometer. The manual is structured into logical volumes, typically covering:
Before clamping a leaf, set up your target microclimate variables within the GFS-Win interface: # Sample data data = 'temperature': [20, 21,
