Large Leaf and Needle Chamber

Large Leaf and Needle Chamber

The Large Leaf and Needle Chamber (6800-13) is ideal for leaves and needles that are big enough to cover most or all of the 36-cm² area leaf aperture. This large surface area gives you unparalleled flexibility to measure different leaf shapes and sizes. The large leaf aperture also improves the accuracy of all measurements. The higher signal-to-noise ratios are especially helpful for seeing differences in low-flux measurements, such as measurements of dark respiration. The high flow rates of the LI-6800—not found in any other photosynthesis system—make measurements over such a large leaf area possible.

The Large Leaf and Needle Chamber has a durable, transparent top for ambient-lighted CO₂ and H₂O flux measurements. The optional Large Light Source attaches directly to this chamber for controlled lighting with any combination of red, green, blue, and white light. The large 6x6-cm leaf area features two high-precision thermocouples for more accurate temperature data.
