Plant photosynthesis meters
Plant photosynthesis meters
The EARS miniPPM is a handheld chlorophyll-fluorescence meter: clip it on a leaf, press the button, and the photosynthesis of the plant is measured within a second. 250 grams, about 3,000 measurements per charge, one-year warranty, shipped from the Netherlands. Two models, depending on how deep you want to look.

What growers and researchers use it for
Herbicide efficacySee the effect of a treatment on photosynthesis within hours instead of waiting for visible damage.
Quality of plants, vegetables and fruitAn objective vitality reading for grading, storage and transport decisions.
Seedling screening for breedingRank seedlings and lines by photosynthetic performance early in the programme.
Greenhouse light climateMeasure the light level at which to start screening: screen once the yield drops below 40%.
Irrigation managementDetect drought stress in the leaf before it shows.
EducationA direct look at how healthy a plant is and how it grows.

About EARS
EARS Plant Photosynthesis Monitoring B.V. in Wageningen has worked on chlorophyll-fluorescence measurement since 1983 and patented its Plant Photosynthesis Meter in the 1990s. The miniPPM is the third generation: smaller, lighter and simpler, without compromising on accuracy. Optional on request: 12 V fast charger, RS-232 / RS-485 port, wireless PC link and a tripod stand.
