1. Android 7.1 smart operating system, with an ARM Cortex-A7 main control chip and RK3288/4-core processor, operating at 1.88 GHz for faster speed and greater stability.  

2. Can test over 200 items, including soil, fertilizers, crops, food, water quality, and the environment, offering multi-functional use and comprehensive capabilities.

3. Faster testing speed! No need for blank controls or standard calibration, eliminating the cumbersome steps of previous operations. One-button operation allows direct data reading, achieving high efficiency and low consumption.  

4. Features a precision rotating colorimetric cell design for more accurate light source consistency, ensuring testing accuracy.  

5. 12 rotating detection channels enable rapid detection of 12 samples at once, greatly improving detection efficiency and reducing detection costs.

6. Utilizes high-precision filter technology and proprietary analytical methods, with authoritative certification.  

7. Features built-in protection functionality, including a facial recognition camera for login via facial recognition, or the option to set a username and password to prevent unauthorized personnel from accessing experimental data.  

8. Incorporates built-in calibration functionality during testing, with intelligent constant current voltage regulation and automatic light intensity calibration to ensure testing accuracy, and has obtained a “Calibration Certificate” from the Chinese Academy of Metrology.

9. The instrument comes standard with Wi-Fi wireless upload, 4G network transmission, and GPRS wireless remote transmission for rapid data upload.

10. Equipped with a smart cloud agriculture platform, the instrument can upload detection data selectively or in batches via wireless upload after connecting to a wireless network, facilitating data management and long-term analysis for users.

11. The instrument features both USB and Ethernet interfaces, with built-in large-capacity memory, and data can be copied to a USB drive at any time.

12. Users can log in to the cloud platform via mobile phone to view historical data online at any time.

13. The instrument is equipped with a crop expert fertilization system that can calculate recommended fertilization amounts for over 100 types of national agricultural crops and fruit trees based on target yields. It provides scientific guidance for agricultural production based on fertilization formulas. Soil testing and fertilization results can be printed, with the printout including: crop type, fertilizer type, target yield, total requirement, and recommended fertilization plan.

14. Built-in plant nutrient diagnosis standard spectrum, which compares leaf images based on nutrient deficiency images of various crops to diagnose nutrient deficiencies.

15. 4-wavelength professional testing cold light source (red, blue, green, orange), with stable light source wavelengths, no temperature drift during prolonged continuous operation, a lifespan of up to 100,000 hours, excellent reproducibility, and high accuracy.

16. The colorimetric cell section uses standard 1cm colorimetric cells, with no mechanical displacement or wear. The optical path testing positioning is precise, effectively shielding external light interference, ensuring that the test results exceed national standard requirements.

17. The instrument system includes sample pretreatment operation videos. Various sample testing methods can be viewed by clicking the video module, eliminating the need for operators to self-study the manual. This provides convenient and rapid guidance, making it easy for newcomers to operate quickly.

18. The instrument is equipped with a new-generation high-speed thermal printer (no ribbon required), which prints the following information: testing unit, tester, testing item, channel number, absorbance, nutrient content (mg/kg), testing time, and QR code.

19. High-sensitivity 7-inch true-color touchscreen with more efficient and user-friendly operation, high-definition and high-interactivity display, significantly reducing the cumbersome operations and errors of traditional instruments, and obtaining multiple software copyrights.

20. Built-in clock function for convenient recording of operation time and long-term historical traceability.

21. Supports multiple account login with password settings, featuring an efficient UI interface. Different users can freely add and edit testing information, which can be saved for long-term use.

22. GPS functionality: Records latitude and longitude locations during field operations to meet special user requirements.

23. Built-in low voltage warning function displays battery level during testing to prevent data drift. Also includes power failure protection, automatically saving data upon power loss to prevent data loss.

24. Dual AC/DC power supply mode, with a built-in high-capacity rechargeable lithium battery that can operate continuously for over 10 hours when fully charged, and can also be connected to a vehicle power source for charging.

25. High-strength PVC engineering plastic carry case design, durable and easy to carry.
