Handheld reflectance meter with integrated GPS module, USB/Bluetooth communication and dedicated software. Measured parameter: PRI index.
The PlantPen PRI 200 measures Photochemical Reflectance Index in two narrow wavelength bands centered close to 531 nm and 570 nm. PRI is sensitive to changes in carotenoid pigments that are indicative of photosynthetic light use efficiency, the rate of carbon dioxide uptake, or as a reliable water-stress index. As such, it is used in studies of vegetation productivity and stress.
Rugged and compact PlantPens can be favourably used in the field, in the plant biology lab, or for education. A handy leaf clip, simple two-button operation, and a bright display make the PlantPen an easy-to-use instrument that does not disturb investigated plants (no leaf detaching or damaging). It takes four AAA alkaline batteries and is supplied in a robust case.
PRI 210 PlantPen is a reflectance-based device providing a convenient, low-cost method of measuring the relative chlorophyll content of a leaf sample. PlantPen measures and calculates particular reflectance indices to assess chlorophyll content, photoprotecting carotenoids, and other important features in live foliage.
There are two models available:
The PRI 210 measures Photochemical Reflectance Index in two narrow wavelength bands centred close to 531 nm and 570 nm.
PRI is sensitive to changes in carotenoid pigments that are indicative of photosynthetic light use efficiency, the rate of carbon dioxide uptake, or as a reliable water-stress index. As such, it is used in studies of vegetation productivity and stress.
