MINI-PAM-II

leaf chamber with a circular 1 cm diameter sample area. Ventilated on one side by air with adjustable flow rate. The amount of water vapor released to the air flow is determined with high precision humidity sensors. The leaf temperature is measured by an IR sensor located in the chamber bottom. GPS information is tracked by a built-in GPS receiver. A mini quantum sensor is positioned on the sample plane. Ambient CO2 values are monitored by a CO2 sensor facing the outside, at the lower left side of the porometer. For chlorophyll a fluorescence measurements, a fiberoptics port aligns the MINI-PAM/F Fiberoptics at an angle of 60° relative to the measuring plane. Including tripod-mount.

MINI-PAM-II leaf clip socket; The MINI-PAM-II: the 6 AA (Mignon) rechargeable batteries (Eneloop 1.2 V/2 Ah) provide power for more than 6 hours for typical experiments. The porometer alone can be operated for more than 9 hours at maximum flow. Easy battery swap possible.
