    • SPAD-502PLUS chlorophyll meter SPAD502PLUS chlorophyll meter can measure all parameters at the same time in one operation, display in real time, and can store at the same time, real-time measurement of the relative content of chlorophyll or "greenness" of plants. Research on physiological indicators and guidance of agricultural production. SPAD-502PLUS Chlorophyll Price Consultation Tel: 0571-86056609!
    • SPAD502PLUS
    • Instrument introduction:

      The SPAD502PLUS chlorophyll meter can measure the relative chlorophyll content (unit SPAD) or green degree and leaf surface temperature of plants in real time, so as to solve the plant's actual nitro requirements and understand the degree of soil nitro deficiency or whether excessive nitrogen fertilizer has been applied. A portable chlorophyll meter can be used to increase the utilization of nitrogen fertilizer and protect the environment.

      The trend graph shows that the measured multiple sets of data trends will be displayed in the graph, and those data with large differences can be found at a glance, so that they can be valued and analyzed.

      SPAD502PLUS Chlorophyll Meter is widely used in the research of plant physiological indicators and the guidance of agricultural production in scientific research units and universities related to agriculture and forestry.

      Instrument principle:

      Based on the absorption of the visible spectrum of the chloroplast pigment extract, the absorbance of the extract is measured at a specific wavelength using a spectrophotometer, and the content of each pigment in the extract can be calculated by a formula. According to Lambert-Beer's law, the absorbance A of a colored solution is directly proportional to the solute concentration C and the thickness of the liquid layer L, that is, A = αCL Formula: α proportional constant. When the solution concentration is in percent concentration and the thickness of the liquid layer is 1 cm, α is the absorption coefficient of the substance. The absorption coefficients of various colored substance solutions at different wavelengths can be obtained by measuring the absorbance of pure substances of known concentrations at different wavelengths. If there are several kinds of light absorbing substances in the solution, the total absorbance of the mixed liquid at a certain wavelength is equal to the sum of the absorbances of the components at the corresponding wavelength. This is the sum of absorbance. To determine the content of chlorophyll a, b and carotenoids in a mixed extract of chloroplast pigments, you only need to determine the absorbance A of the extract at three specific wavelengths, and according to the chlorophyll a, b and carotenoids at this wavelength The absorption coefficient can be used to determine its concentration. In order to exclude the interference of carotenoids when measuring chlorophyll a and b, the wavelength of the monochromatic light used was selected as the maximum absorption peak of chlorophyll in the red light region.
