Measurements may be recorded on request or automatically at predefined intervals. The data is simultaneously transferred to the RS232 interface. Analog outputs are also provided. The system can be powered either from the mains or from its own rechargeable battery. The battery is lightweight and easily replaceable, to extend the operating time in the field.
Memory is maintained during battery changeover.
A pocket PC is available for portable use, which can be attached to the front of the analyser. The air supply unit is fitted within the analyser housing. PP Systems specializes in the design and manufacture of leaf cuvettes. From this, the photosynthetic rate and stomatal conductance of the enclosed leaf is calculated, stored and displayed. Where possible, the cuvette window comprises an IR filter to minimize solar heating withing the cuvette by reducing infrared radiation.
