SPAD value determination - chlorophyll analyzer

The spad value is a parameter that measures the relative content of a plant's chlorophyll or the greenness of a plant. As our research on plants becomes more and more in depth, our understanding of plants is becoming more and more comprehensive. Here we say that the pad value, has now proved to be a very important value, it can help you understand the plant's nitro needs and guide you to fertilize.

So, how does the padding guide fertilization? It turns out that chlorophyll is the main substance that absorbs light, and the pad value is a sign of chlorophyll content. There is a certain relationship between them. If we can measure the content of chlorophyll with the instrument, we can guide the padding value, and the padding value follows. Nitrogen content has a specific proportional relationship. Nitrogen fertilizer is the main fertilizer of plants. Therefore, if the padding value is high, it means that the amount of nitrogen fertilizer is sufficient and there is no need to apply fertilizer; if the padding value is relatively low, it means that the content of nitrogen fertilizer is low, and timely fertilization is needed. .

The spad value chlorophyll meter is an instrument that can quickly determine the plant's padding value. The SPAD-502Plus measures the relative amount of chlorophyll in the current leaf by measuring the absorption of leaves in two wavelength bands. The spad value chlorophyll meter can directly display the pad value, as well as other parameters such as the number of measurements, and it can display the pad value range from -9.9 - 199.9 SPAD units. The spad chlorophyll meter is a high-precision instrument that achieves an accuracy of ±1.0 SPAD units. Therefore, if you are a laboratory worker, you have relatively high requirements for the determination of chlorophyll content, or are specialized in agricultural workers, and have relatively high requirements for the frequency and results of determination of chlorophyll content, then, the value of sap chlorophyll Instrument is a good choice, you can consult the 24-hour service hotline for further understanding.
