product Characteristics

Chlorophyll Meter

Introduction about chlorophyll Meter:

A chlorophyll meter can instantly measure the relative chlorophyll content or “greenness” of a plant. The chlorophyll content in a plant’s leaves indicates the condition of the plant itself. The leaves of a well-growing plant will contain more chlorophyll. The content of chlorophyll is the same as that of nitrogen in the leaves. There is a very close relationship with the content, so the chlorophyll measurement value can also indicate the real nitro demand of the plant. Through this instrument, it is beneficial to apply nitrogen fertilizer reasonably, improve the utilization rate of nitrogen, and protect the environment (to prevent the application of excessive nitrogen fertilizer and pollute the environment, especially the water source)

SPAD-502 PLUS chlorophyll Meter can measure relative content of chlorophyll,non-destructive to leaves. Measured datum will be displayed in trend graph. It can be used to enhance the utilization rate of nitrogen fertilizer.
