Handy PEA is a compact, highly portable continuous-excitation type chlorophyll fluorimeter designed for the analysis of the fast-induction kinetics associated with chlorophyll fluorescence.
The rugged yet lightweight design makes Handy PEA particularly suitable for rapid, large scale screening of samples in the field or greenhouse in both research and teaching applications.

The HPEA/LPA2 is the second generation liquid-phase adapter for the Handy PEA chlorophyll fluorescence measuring system. It has been designed to simply connect to the Handy PEA control unit as a direct replacement for the standard sensor head. It provides measurements of the fast fluorescence kinetics from samples such as suspensions of chloroplasts or algae and any other photosynthetically active suspension. The curves are recorded by the Handy PEA control unit at acquisition rates of up to 100kHz. The key fluorescence parameters measured are displayed on the LCD display of the Handy PEA control unit before being saved to memory. Recorded traces may then transferred to the PEA Plus software for further analysis.

The FMS 2 is a lightweight, field portable fluorescence instrument which uses the pulse-modulated principle to monitor chlorophyll fluorescence. It is therefore suitable for non-intrusive sampling from tissue operating under natural light or working in conjunction with other techniques such as infra-red gas analysis (IRGA).



At the heart of the system is the field-rugged FMS2 control unit; this is a (18 x 10 x 10 cm) housing which is light enough (2.0 Kg) to be carried and operated from its shoulder bag. It contains the integral light sources and temperature compensated electronics needed for fluorescence measurement.
