Chlorophyll analyzer

Chlorophyll analyzer

Instrument usage

Among the factors that affect plant growth, chlorophyll is an important one because it can reflect important information about plant growth,rightNThe application of fertilizer can provide guidance.YLSChlorophyll analyzerCan measure the relative chlorophyll content of plants in real-time (unit)SPAD）Or“Green degree”This can help you understand the true nitrate demand of plants and help you understand the degree of soil nitrate deficiency or whether excessive nitrogen fertilizer has been applied. You can use this instrument to increase the utilization rate of nitrogen fertilizer and protect the environment (preventing excessive nitrogen fertilizer from contaminating the environment, especially water sources).

working principle

twoLEDThe light source emits two types of light, one is red light(650nm)One is infrared light(940nm)Two types of light penetrate the blade and hit the receiver. The light signal is converted into an analog signal, which is amplified by an amplifier and then converted into an analog signal/The digital converter converts it into a digital signal, which is processed by a microprocessor and calculatedSPADValue and display on the LCD screen.

（1）Calibration and calculation of chlorophyll meter measurement values, twoLEDSequential light emission, the received light is converted into electrical signals, and the ratio of light intensity is used for calculation.

（2）After clamping the sample with the pressure head, twoLEDOnce again emitting light, the light transmitted through the blades hits the receiver and is converted into an electrical signal, and the intensity ratio of the transmitted light is calculated.

（3）Steps1and2The value is used for calculationSPADThe measured value represents the current relative chlorophyll content of the clamped sample leaves.

（4）The measured chlorophyll value and its applicationSPAD-502PlusCompare the values measured by a portable chlorophyll meter and correct them through a program.
