EARS Plant Photo Synthesis Meter miniPPM-100
The miniPPM is the third generation of the EARS Plant Photosynthesis Meter, a handheld modulated saturation-pulse fluorometer. It uses the chlorophyll fluorescence of a leaf to measure photosynthesis: hold the clip on the leaf, press the button, and the measurement is complete within a second. Laboratory tests show stable, reproducible results. Compact, light (250 grams) and simple to operate, it fits research, education and everyday practice in agriculture and horticulture.
EARS Plant Photosynthesis Monitoring B.V. (Wageningen, the Netherlands) has developed chlorophyll-fluorescence instruments since 1983 and patented its Plant Photosynthesis Meter in the 1990s. All miniPPM meters ship from the Netherlands with a one-year warranty.
What the miniPPM-100 measures
- Fluorescence in ambient light (F)
- Maximum fluorescence (Fm)
- Photosynthesis yield (Y)
- Measurements at all light levels
The miniPPM-100 is the affordable choice for growers, advisers and schools who want a quick, reliable reading of plant vitality. Results are shown on the display; for stored series, PAR, photosynthesis rate and light curves choose the miniPPM-300.
