Description
designed to help users improve crop quality and increase crop yield by providing an indication of the amount of chlorophyll present in plant leaves. The chlorophyll content of plant leaves is related to the condition of the plant, and thus can be used to determine when additional fertilizer is necessary. By optimizing nutrient conditions, healthier plants can be grown, resulting in a larger crop yield of higher quality.
Trend graph display Changes in measurement data over time can be seen, and abnormal values can be noticed at a glance. Compact and lightweight for portability The SPAD-502Plus is small enough to fit in a pocket and is extremely lightweight (only 200 g) so it can be easily taken anywhere. Quick, easy measurements Measurements are taken by simply inserting a leaf and closing the measuring head. It is not necessary to cut the leaf, so the same leaf can be measured throughout the growing process. Water-resistant The SPAD-502Plus is water-resistant (IPX-4), so it can be used outside even in the rain. *It is not immersible, and should not be cleaned with water. Low power consumption The SPAD-502Plus uses LED light sources, resulting in extremely low power consumption. One set of two AAsize alkaline-manganese batteries can provide approximately 20,000 measurements. Small measuring area The measuring area is only 2 x 3 mm, allowing measurements of even small leaves. A sliding depth stop is included for accurate positioning on sample leaves. High accuracy High measuring accuracy (± 1.0 SPAD unit for rice-plant leaves) allows close examination of growing conditions.
