Product description: 
 The multi-purpose all-plant leaf area, root, rings, leaf color analyzer is a convenient, in the field or laboratory use analytical instruments, the accuracy is much higher than traditional analyzer (transmission or the type of camera). Of an international standard, accurately, quickly and without damage of the blade of the leaf area and leaf color parameters, measurement area of ??the harvested plant leaves and other sheet objects, but also for leaf color analysis (including by leaf color Automatic file queries, for the rapid evaluation of the plant or crop N status). The plant ring analysis module can be used for dendrochronology, ring the ecological environment change science, dendroclimatic, the study of geographical science, archeology. Plant roots analysis module is an optional module, the professional roots for washing roots can analyze the root length, diameter, area, volume, root count, its powerful, simple operation, applied to the root morphology and tectonic studies . The instrument is a combination of plants, crops, leaf area, root, ring, leaf color and four major aspects of the analysis function, widely used in agriculture, forestry, meteorology and other departments. 
 Technical parameters: 
 ◆ leaf analysis of the measured parameters: leaf area (which can be accumulated area), leaf area (cumulative area), leaf perforation area (cumulative area), leaf length and width, petiole length, leaf perimeter (not leaves holes in impact) leaf perimeter, aspect ratio of leaves, leaf shape factor, custom length and angle measurements, the height of the blade serrated, width, measuring the number of leaves hole area measurement; envelope (between the teeth - tooth line length), coated the formation of the projection area; irregular leaf morphology analysis, secondary the truecolor pathological analysis of leaf color analysis (including the appearance of the leaf color automatically for the nitrogen status of the sub-file query evaluation). 
 ◆ plant ring measurement and analysis: the automatic interpretation of the ring number, the average width of each ring, earlywood and latewood width, ring to cut the angle and area. Can be automatically divided into the ring boundary, border of earlywood, latewood boundary, as well as to identify a very narrow tree rings, can interact to remove the pseudo-ring, insert the broken ring. Analysis of the measurement data obtained have further cross-dating, the generated chronology, data analysis and processing capacity. 
 ◆ plant root analysis of the measurements: 1) the total root length; 2) average diameter of the root; 3) the root of the total area; 4) the total volume; 5) apical count; 6) bifurcation count; 7) overlap count; 8) root diameter class distribution parameters. 
 Match the specialized lighting system, high-resolution color or black and white images to the addition to the shadows and uneven, and effectively guarantee the image quality. The non-statistical methods to measure and calculate the overlapping part of the root length can read TIFF, BMP, JPEG standard image format. Plant leaf area plant leaves than on the sub-file
