1. Rapidly detect available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, nitrite, calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, molybdenum, and other trace elements, as well as lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium, and other heavy metals.

2. Android smart operating system, featuring more efficient and user-friendly operation. The instrument is standardly equipped with Wi-Fi connectivity and 4G connectivity, enabling wireless and rapid data upload.

3. Built-in crop expert fertilization system, capable of calculating recommended fertilization amounts for over a hundred types of national agricultural crops, fruit trees, and economic crops based on target yields, providing scientific guidance for agricultural production according to fertilization formulas.

4. Features a dual-row multi-channel design, enabling rapid testing of 12 samples at once. All testing parameters can be analyzed simultaneously across all channels, significantly enhancing testing efficiency and reducing costs.

5. Includes built-in plant nutrient diagnosis standard spectra, allowing comparison of leaf images based on nutrient deficiency patterns in various crops to diagnose nutrient deficiencies or excesses.

6. Utilizes high-precision filter plate technology and proprietary analytical methods. The colorimetric cell section uses standard 1cm colorimetric cells, eliminating mechanical displacement and wear, with precise optical path testing and positioning.

7. The instrument features 4GB of memory for long-term data storage and is equipped with an upload platform, enabling direct wireless data transmission without a data cable, facilitating data management and long-term analysis.

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

9. Features a high-sensitivity 7-inch capacitive touchscreen with high-definition and high-interactivity display, significantly reducing the complexity and errors associated with traditional instruments.

10. Each channel is equipped with a four-wavelength cold light source, with all light sources maintaining constant current and voltage regulation to ensure wavelength stability. The silicon semiconductor serves as the signal reception system, with a lifespan of up to 100,000 hours. It offers excellent reproducibility and high accuracy.

11. The instrument is housed in a high-strength PVC engineering plastic carry case, which is durable and easy to transport. It supports both AC and DC power supply, enabling field testing with pre-packaged reagents.
