2. The Android intelligent operating system adopts more efficient and user-friendly operation, and the instrument comes standard with WiFi networking function, 4G networking function, and wireless fast data upload.

3. The built-in crop expert fertilization system can calculate recommended fertilization amounts for over a hundred national agricultural, fruit tree, and economic crops based on their target yields, and scientifically guide agricultural production according to fertilization formulas.

4. Adopting a dual row multi-channel design, it can quickly detect 12 samples at once, and all detection items can be detected simultaneously in all channels, greatly improving detection efficiency and reducing detection costs.

5. Built in plant nutrition diagnostic standard map, based on images of nutrient deficiency in various crops, conduct leaf comparison to diagnose abundance and deficiency.

6. Adopting high-precision filter technology and independent patent analysis method (patent number: ZL 2018 2 1777724.7), the colorimetric groove adopts a standard 1cm colorimetric dish without mechanical displacement or wear, and the optical path testing positioning is accurate, ensuring that the detection results are better than the national standard requirements.

7. The instrument has 4G memory, which can store data for a long time and is equipped with an upload platform. No data cable is required, and data can be directly uploaded wirelessly, making it convenient for data management and long-term analysis.

8. The instrument is equipped with a new generation high-speed thermal printer, which can automatically print inspection reports and QR codes upon completion of testing.

9. High sensitivity 7-inch capacitive touch screen, high-definition and high interactive display, greatly reducing the tedious operation and errors of traditional instruments.

10. Each channel is equipped with a four wavelength cold light source, and all light sources achieve constant current and voltage regulation to ensure wavelength stability. Silicon semiconductors, as signal receiving systems, have a lifespan of up to 100000 hours. Good reproducibility and high accuracy.

11. The high-strength PVC engineering plastic carrying case is designed to be sturdy, durable, and easy to carry. It is powered by both AC and DC, and can be used for field testing of finished pharmaceuticals.
