Chlorophyll Analyzer

The use of chlorophyll analyzer_chlorophyll analyzer price_the principle of chlorophyll analyzer
Product model: YF-LS

Instrument use:
The chlorophyll analyzer can instantly measure the relative chlorophyll content or "greenness" of a plant. The chlorophyll content in the leaves of the plant shows the condition of the plant itself. The leaves of well-growing plants will contain more chlorophyll. The content of chlorophyll is closely related, so the chlorophyll measurement value can also explain the true nitro demand of the plant. With this instrument, it is beneficial to apply nitrogen fertilizer reasonably, improve the nitrogen utilization rate, and protect the environment (prevent application of excessive nitrogen fertilizer) And pollute the environment, especially water).
Measurement principle:
The chlorophyll analyzer determines the relative quantity of the current chlorophyll of the leaf by measuring the transmission coefficient of the leaf in two wavelength ranges, that is, the two wavelength regions where the chlorophyll chooses to absorb light of a specific wavelength, and the measured value is calculated according to the amount of light transmitted by the leaf .
