YLS-B Portable plant Chlorophyll meter
Introduction
Chlorophyll plays a crucial role in the photosynthesis of plants. Its content is an important indicator of plant nutrition stress, photosynthetic capacity, and growth conditions. Chlorophyll content measurement can be used to monitor the growth and development conditions of plants, thereby making scientific guidance of
cultivation, fertilization and management, ensuring the good growth vigor, and enhancing crop quality and yield. As a result, it is of great significance for precision agriculture and forestry.
Feature
Chlorophyll meter by measuring the leaf in two wavelength range of light transmittance relative quantity to determine the current leaf chlorophyll, which is in the chlorophyll choose two wavelength region absorb certain wavelengths of light, measured value is calculated according to the amount of transmitted light blade.
