Product Introduction:

Complete supporting facilities: This instrument integrates medicine, equipment, and instruments, without the need for user provided accessories, equivalent to a small mobile laboratory, convenient to carry, and can also be used for field mobile testing. Suitable for agricultural service departments, agricultural material distributors, cooperatives, fertilizer manufacturers, and large growers to conduct soil testing and fertilization.

Full testing function: The testing items are comprehensive both domestically and internationally. Except for standard reagents, all other types of reagents can be added and purchased.

Easy to operate and fast, equipped with a complete set of accessories and ready to use finished drugs upon opening, without the need for configuration.

Multi functional and complete testing items:

Soil nutrients: soil ammonium nitrogen, soil available phosphorus, soil available potassium, soil nitrate nitrogen, soil hydrolyzed nitrogen, soil total nitrogen, soil total phosphorus, soil total potassium, soil organic matter (Qiu Lin method), soil organic matter (extraction method), pH value, salt content, and moisture.

Testing efficiency:

Simultaneous extraction and determination of multiple nutrients such as available N, P, and K in soil (drafter of the industry standard for rapid testing by the Ministry of Agriculture).

Testing speed: Under normal proficiency, it takes 20 minutes to test one soil sample (N, P, K) for three items (including reagent preparation and soil sample pre-treatment time). At the same time, it takes ≤ 40 minutes to test three soil samples (N, P, K), and ≤ 1 hour to test eight soil samples simultaneously.

Functional features:

1. This instrument combines various functions in one, without the need for user provided accessories, and can flexibly flow for detection.

2. The Android intelligent operating system adopts ARM Cortex-A7 as the main control chip, RK3288/4 core processor, with a main frequency of 1.88GHz, faster operation speed, and stronger stability.

3. Six detection channels (solid-state design) can quickly detect six samples at once, greatly improving detection efficiency and reducing detection costs.

4. Built in calibration function during the detection process, intelligent constant current and voltage regulation, and automatic light intensity calibration ensure detection accuracy.

5. The built-in crop expert fertilization system can calculate the recommended fertilization amount for over a hundred national agricultural economic crops, fruit trees, and other target yields, and scientifically guide agricultural production based on fertilization formulas. The soil testing formula fertilization results can be printed, including crop types, fertilizer types, target yield, total demand, and recommended fertilization plans.

6. The instrument comes standard with WiFi wireless upload, 4G network transmission, and GPRS wireless remote transmission function, allowing for quick data upload.

7. The instrument is equipped with a large capacity memory, which supports viewing all historical detection records and transmitting all detection data.

8. Equipped with a smart cloud agriculture platform, the instrument can selectively or in bulk upload detection data wirelessly after being connected to the wireless network, facilitating long-term data management and visual analysis for users.

9. The instrument has both USB and Ethernet interfaces, and can copy data from a USB drive at any time.

10. You can log in to the cloud platform anytime with your mobile phone and view historical data online

11. Built in plant nutrition diagnostic standard map, based on images of nutrient deficiencies in various crops, leaf comparison is performed to diagnose abundance and deficiency.

12. 4 wavelength professional testing cold light source (red, blue, green, orange), stable light source wavelength, long-term continuous operation without temperature drift phenomenon, with a lifespan of up to 100000 hours, good reproducibility, and high accuracy.

13. The colorimetric cell adopts a standard 1cm cuvette, which has no mechanical displacement or wear. The optical path is tested and positioned to effectively shield external light interference and ensure that the detection results are better than the national standard requirements.

14. The instrument system comes with sample pre-treatment operation videos, and various sample detection methods can be viewed by clicking on the video module. Testing personnel do not need to self-study the manual, making teaching and guidance convenient and fast for beginners to operate quickly.

15. Equipped with a new generation of high-speed thermal printer (without ribbon), the printed content includes information such as testing unit, testing personnel, testing items, channel number, absorbance, nutrient content (mg/kg), testing time, and QR code

16. A highly sensitive 7-inch true color touch screen with more efficient and user-friendly operation, high-definition and interactive display, greatly reducing the tedious operation and errors of traditional instruments.

17. Built in clock function, convenient for time recording and long-term historical tracing.

18. Multiple account passwords can be set for login, with an efficient UI interaction interface. Different users can freely add, edit, and detect information. After saving, it can be used for a long time.

19. GPS function: It can record longitude and latitude locations during field operations to meet special user needs.

20. Equipped with a built-in low voltage prompt function, it can clearly indicate the battery level during detection, avoiding test data deviation. At the same time, it has a power-off protection function, which automatically saves data during power-off to prevent data loss.

21. The AC/DC dual-purpose power supply mode is equipped with a large capacity rechargeable lithium battery, which can work continuously for more than 10 hours when fully charged. At the same time, it can be connected to an external vehicle power source for energy storage.
