The new miniPPM is there...
A unique, affordable instrument, with excellent properties, that replaces the previous series.
The new PPM-300 automatically measures light-photosynthesis curves. To determine species light climate and productivity. Also for determining screening light levels in greenhouses.
PPM and MLHD successful in China
7% Yield increase and 50-70% herbicide reduction in Maize.
1983: First chlorophyll fluorescence meausurements on grass growing on contaminated soil, with TNO-TPD
1985-93: First laser chlorophyll fluorescence measurements on trees, with IROE-CNR, Florence.
1990: Laser Environmental Active Fluorosensor LEAF developed in NL.
1992: First sale of EARS Plant
Photosynthesis Meter (PPM) to ESA.
1991-99: Several research projects with LEAF and PPM.
1998: Publication new fluorescence photosynthesis model (PDM).
1999: Patent on PPM.
2002-03: Project Plant-intelligent
Management Systems in Glass Horticulture (PIRSIG).
2004-08: PPM introduction in Chinese agriculture for reduction of herbicide use
Photosynthesis meter
The EARS Plant Photosynthesis Meter (PPM) measures the photo-synthetic light use of plants. Because of its low weight, the instrument is very suitable for use in laboratory and field. Just press the button and the measurement is completed within a second. In addition long measuring series can be done automatically. For this reason the PPM has a wide range of applications in research, education and practice. The companyEARS Plant Photosynthesis Monitoring Ltd has carried out research into the application of chlorophyll fluorescence since 1983. The first hand held photosynthesis meter was launched in 1992. Since then we have continued research and development in this field, with a focus on measuring technique and practical application. Therefore do not expect a long list of fluorescence parameters on this site. We do not refer to them if they are purely theoretical and have no practical meaning.
