ECA-051 chlorophyll analyzer Introduction: This instrument adopts a photoelectric non-destructive testing method to measure chlorophyll content: based on chlorophyll absorbing red light with a wavelength of 650 nm, but not infrared light with a wavelength of 940 nm. The emission and reception of infrared light are mainly to eliminate the influence of leaf thickness and other factors on the measurement results. After the red light reaches the leaves, some of it is absorbed by the chlorophyll in the leaves, and a small amount is reflected. The rest is converted into corresponding electrical signals through the leaves by the receiver, and then converted into digital signals through an A/D converter. The microprocessor uses these digital signals to calculate the relative content of chlorophyll, which is represented as SPAD value, displayed and stored. Technical parameters: 1. One screen can display parameters such as measurement values, battery usage, sample number, group number, time and date; 2. Large storage capacity: 4G TF card, 5 million sets of data, EXEL format 3. Measurement accuracy: ± 1 SPAD (SPAD reading between 0 and 50) 4. Measurement range: 0-99.9SPAD 5. Measurement area: Ф 6mm 6. Reproducibility: ± 0.5 SPAD (SPAD reading between 0 and 50) 7. Measure light at 650nm and 940nm 8. Minimum measurement interval: less than 2 seconds, display resolution: 0.1 9. Can calculate the average value of a plant's leaves 10, 4 No. 7 batteries 11. Boundary dimensions: 150 * 60 * 35 (mm) 12. Weight: 350g
