Clear-top Chamber

Clear-top Chamber

The Clear-top Leaf Chamber (6800-12A) has a durable, transparent top for ambient-lighted CO₂ and H₂O flux measurements. The optional Small Light Source attaches directly to this chamber. Several options for measurable leaf area are available with aperture inserts. To fill the chamber area—and easily calculate leaf area size—swap in one of three interchangeable apertures for different leaf area apertures: 3x3 cm, 2x3 cm, and 1x3 cm.

Leaf temperature is measured by a high-precision thermocouple mounted in the chamber, while a Gallium Arsenide Phosphide (GaAsP) photodiode measures photosynthetically active radiation (PAR) inside the chamber. Plated surfaces minimize H₂O adsorption. Durable gaskets form a seal around irregular leaf surfaces.
