I. Product Introduction
JC-YLS chlorophyll analyzer can measure the relative chlorophyll content (unit SPAD) or "green degree" of plants in real time, so as to understand the actual demand for nitro-group of plants and help you understand the degree of soil nitro deficiency or excessive application of nitrogen fertilizer. You can use this instrument to increase the utilization rate of nitrogen fertilizer and protect the environment (to prevent pollution of the environment, especially water sources, by applying too much nitrogen fertilizer).

II. Product Characteristics
Two LED light sources emit two kinds of light, one is red light (650 nm), the other is infrared light (940 nm). Two kinds of light penetrate the blade and hit the receiver. The light signal is converted into analog signal, the analog signal is amplified, the analog/digital converter is converted into digital signal, the digital signal is processed by microprocessor, and the SPAD value is calculated. And displayed on the LCD screen. 
1. Calibration and calculation of the measured value of chlorophyll meter. Two LEDs emit light sequentially. The received light is converted into electrical signals. The ratio of light intensity is used to calculate. 
2. After the sample is clamped by the indenter, the two LEDs emit light again. The light transmitted through the blade strikes the receiver and is converted into electrical signals. The intensity ratio of the transmitted light is calculated. 
3. The values of steps 1 and 2 are used to calculate SPAD measurements, which indicate the current relative chlorophyll content of the clamped sample leaves.
