- Handy-PEA is a compact, highly portable continuous-excitation type chlorophyll fluorescence analyser.
- 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.
- Handy-PEA utilises the continuous excitation fluorescence measurement principle.
- High time resolution (100KHz initial sampling rate) electronics and saturating levels of illumination (3000µmol m-2 s-1) permit accurate monitoring of the time dependent fluorescence induction kinetics observed when a sample is strongly illuminated after a period in darkness (Kautsky effect).
- Typical measurements take only 1 second, providing a very high throughput capability for large scale screening of samples.
- Handy-PEA offers a high degree of measurement flexibility for research applications involving longer duration measurements or pre-programmed user-defined multi flash protocols
- Integral switch mode battery charger 8-13.5V input (nominal 12V input)
- Illumination -Focused array of ultra-bright red LED's with NIR short pass cut-off filters.
- Detector - Fast response PIN photodiode with RG9 long pass filter.
- Electronics - 16 bit microprocessor, 12 bit resolution, A/D 10µsec acquisition rate, 8 bit DAC for light source control, real time clock.
