Details
• Handy-PEA is a compact, highly portable continuous-excitation type chlorophyll fluorescence analyzer.
• 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 utilizes 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.
• Weight - 565gms
• Battery - 3 rechargeable (Ni-MH) 3.6V 1.8Ahr.
• Battery Life - Typically 8 - 9 hours when performing 1 second recordings at 120 measurements/hr.
• Integral switch mode battery charger 8-13.5V input (nominal 12V input)
• Display - 8 line x 20 character LCD display.
• Illumination -Focused array of ultra-bright red LED's with NIR short pass cut-off filters.
• Peak wavelength 650 nm.
• Spectral-line half width 22 nm.
• Max. intensity at leaf surface >3000µmol m-2 s-1.
• 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.
• Record Length - 0.1 - 300 seconds
• Memory - 512K battery backed RAM (sufficient for up to 1000 one second duration recordings with full trace data).
