Model PTM-48A - Photosynthesis Monito Brochure

The PTM-48A Monitor is truly state-of-the-art system for long-term automatic recording physiological characteristics of intact plants. The Monitor has four inputs for original automatic self-clamping leaf chambers. The chamber is normally open and shuts the leaf only for 30 seconds to take readings of both CO2 and H2O exchange rates. The short measurement time provides minimal disturbance of natural leaf conditions. The standard LC-4B Leaf Chamber has a 20 cm2 aperture suitable for a wide variety of broad-leaf plants.
