CHLOROPHYLL METER A lightweight handheld meter for measuring the chlorophyll content of leaves without causing damage to plants.

The SPAD-502Plus is a compact meter 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. The graph below shows the spectral absorbance of chlorophyll extracted from two leaf samples using 80% acetone. From the diagram, it can be...

Features Trend graph display Data memory Changes in measurement data over time can be seen, and abnormal values can be noticed at a glance. The SPAD-502Plus has memory space for 30 measurements.
