Overview
The PTM-48A monitoring device is a real art level measurement system used for long-term automatic monitoring of plant physiological characteristics. The monitor has four output channels for initial self positioning of the leaf air chamber. Normally, the chamber is opened and closed every 30 seconds, and readings of the carbon dioxide and water vapor exchange rates are obtained. The short measurement time has a very small impact on the natural condition of the leaf surface. Standard LC-4B gas ..
