    Product introduction:
    The portable chlorophyll meter is used to measure the relative content of chlorophyll in plant leaves. Plant growth is inseparable from a variety of nutrients, so we will apply a variety of fertilizers to plants, of which nitrogen fertilizer is the most common fertilizer. If too little fertilizer is applied, plants need not enough nutrition; if too much fertilizer is applied, it will lead to waste of fertilizer, and even lead to groundwater pollution. By measuring the relative content of chlorophyll, we can truly understand the demand of plants for nitrogen fertilizer, so as to provide the utilization rate of nitrogen fertilizer, and also protect the water from being polluted by too much nitrogen fertilizer.
    Principle:
    Based on the principle of monochromatic light, the red light (650nm) and infrared light (940nm) emitted by LED light source penetrate the blade and hit the receiver. The optical signal is converted into analog signal, which is amplified by amplifier and converted into digital signal by analog / digital converter. The digital signal is processed by microprocessor, and the SPAD value is calculated and displayed on the LCD screen.
