Soil Nutrient Tester

I. Product Overview

Multi-channel soil-nutrient detector (popular model for agro-input dealers and agro-technical systems). A new-generation intelligent instrument with built-in soil-testing formula fertilization, atlas diagnosis, QR-code printing, data upload, and all accessories needed for testing - the user only needs to provide pure water to accurately determine nitrogen, phosphorus, potassium, organic matter, pH and salt content!

Complete accessories: This instrument integrates reagents, apparatus and meter into one unit. It is portable and convenient to carry, equivalent to a small mobile laboratory. Users need not prepare their own accessories and it can be flexibly used for on-site and mobile testing. It is suitable for agricultural service departments, agro-input dealers, cooperatives, fertilizer manufacturers and large growers for soil testing and fertilizer recommendation, and for identifying genuine/fake fertilizers and environmental-protection testing applications. Complete test functions: Test items are comprehensive, covering both domestic and international ranges; besides the standard reagents, various other reagents can be optionally purchased. Simple and fast operation: Complete sets of accessories and ready-to-use reagents are provided; no preparation is needed.

II. Test Items

Soil nutrients: ammonium nitrogen, available phosphorus, available potassium, nitrate nitrogen, hydrolyzed nitrogen, total nitrogen, total phosphorus, total potassium, soil organic matter (Kjeldahl method), soil organic matter (extraction method), soil total organic carbon (TOC), soil C/N ratio, pH, salt content, moisture. Soil medium/trace elements: calcium, magnesium, sulfur, silicon, boron, iron, copper, manganese, zinc, chlorine, molybdenum. Soil heavy metals: lead, arsenic, cadmium, chromium, mercury, nickel, aluminum, fluorine, titanium, selenium.

III. Test Efficiency

For soil, available N, P, K and many other nutrients are simultaneously extracted and determined in one step (drafting unit of the Ministry of Agriculture rapid-test industry standard). Test speed: under normal proficiency, one soil sample (N, P, K) takes 20 minutes (including reagent preparation and sample pretreatment); testing three soil samples (N, P, K) ≤40 minutes; testing 8 soil samples ≤1 hour. One fertilizer sample (N, P, K) ≤50 minutes; testing three fertilizer samples (N, P, K) ≤1.5 hours.

IV. Test Error

Soil N/P/K error ≤1%, organic matter error ≤2%, trace-element relative error ≤5%; single fertilizer item error ≤0.5%, N/P/K three-item error ≤1%; heavy-metal relative error ≤5%.

V. Key Features

1. This instrument integrates all functions into one unit; users need not prepare their own accessories and can perform flexible on-site and mobile testing.

2. Android smart operating system; the main control chip uses ARM Cortex-A7, RK3288 quad-core processor at 1.88 GHz for faster operation and stronger stability.

3. ★ 6 rotating detection channels allow up to 6 samples to be tested at once, greatly improving detection efficiency and reducing cost.

4. Built-in calibration during detection, intelligent constant-current and stabilized voltage, and automatic light-intensity calibration ensure detection accuracy.

5. Standard Wi-Fi wireless module for fast data upload; an optional 4G module enables outdoor data upload.

6. Equipped with a Smart Cloud Agriculture Platform; after connecting to a wireless network, detection data can be selectively or batch uploaded for long-term data management and visual analysis.

7. Both USB and Ethernet interfaces with built-in large-capacity memory; data can be copied anytime via U disk.

8. Built-in large-capacity memory supports viewing all historical detection records and transferring all detection data.

9. ★ Detection data can be viewed anytime on a mobile phone by logging into the cloud platform.

10. ★ Built-in crop-expert fertilization system calculates recommended fertilization amounts for target yields of over a hundred national economic crops and fruit trees, guiding agricultural production scientifically based on fertilizer formulas. Soil-testing formula results can be printed, including crop type, fertilizer type, target yield, total demand, and recommended plan.

11. ★ Built-in standard plant-nutrition diagnosis atlas; compare leaf images of crops with nutrient deficiencies to diagnose surplus or shortage.

12. 4-wavelength professional cold light source (red, blue, green, orange) with stable wavelength, no thermal drift during long continuous operation, lifespan up to 100,000 hours, good repeatability and high accuracy.

13. The colorimetric cell uses a standard 1 cm cuvette with no mechanical displacement or wear; precise optical-path positioning effectively shields external light interference, ensuring results better than national standards.

14. The instrument system includes sample-pretreatment operation videos; testing personnel can watch the video module for each method without reading the manual, enabling quick and convenient guidance for beginners.

15. New-generation high-speed thermal printer (no ribbon); print content includes testing unit, operator, test item, channel No., absorbance, nutrient content (mg/kg), test time, and QR code, etc.

16. High-sensitivity 7-inch HD color touch screen for efficient and user-friendly operation with clear, highly interactive display, greatly reducing the tedious operation and errors of traditional instruments, and with multiple software copyrights.

17. Built-in clock function for convenient operation-time recording and long-term traceability.

18. Multi-account login with user name and password and an efficient UI; different users can freely add and edit detection information for long-term use.

19. GPS function records latitude/longitude during field work to meet special user needs.

20. AC/DC dual power supply; built-in large-capacity rechargeable lithium battery with power display and low-voltage alarm; can work continuously for over 10 hours when fully charged, and can be connected to vehicle power for charging.

21. ★ The instrument has a Chinese/English switch function to meet export requirements.

22. High-strength PVC engineering-plastic carrying case, sturdy, durable and portable.
