Instrument use: The chlorophyll meter can measure the relative chlorophyll content or "green degree" of the plant instantly. The chlorophyll content in the leaves of the plant indicates the condition of the plant itself, and the leaves of the well-growing plant contain more chlorophyll. The content of chlorophyll is closely related to the content of nitrogen in leaves. Therefore, the measured value of chlorophyll can also explain the real demand for nitro-nitro in plants. This instrument is helpful for the rational application of nitrogen fertilizer and the improvement of nitrogen utilization rate. And can protect the environment (prevent excessive application of nitrogen fertilizer and make the environment, especially water pollution.
