PTM-48M Phytosynthesis and Transpiration Monitor

A new all-in-one instrument for monitoring plant state and environment

Overview

The PTM-48M Monitor is truly state-of-the-art system for long-term automatic recording of intact plant physiological status. 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 rate with 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. The monitor has also eleven inputs for Optional Sensors. The Monitor provides fully automatic continuous operation. Sampling rate is selectable from 5 to 120 minutes. The RS-232 and RS-485 ports may be used for communicating with the PC. The Terminal Emulator software allows controlling system setup and operation as well as data downloading and export in TXT or CSV format for further processing and analysis.

Optional Sensors PIR-1 Photosynthesis Radiation Sensor; TIR-4 Total Irradiance Sensor; ATH-2 Air Temperature and Humidity Sensor; SMS-2 Soil Moisture Sensor; LT-2M Leaf Temperature Sensor; SF-4M, SF-5M Sap Flow Relative Rate Sensors; SD-5M or SD-6M Stem Microvariation Sensors; DE-1M Electronic Point Dendrometer; FI-LM, FI-MM, FI-SM and FI-XSM Fruit Growth Sensors; SA-20 Stem Auxanometer.

See Phytomonitoring Sensors (Industrial Series) for more details about optional sensors.
