Soil testing and fertilizer blending equipment

The soil fertility tester is an all-in-one device combining reagents, instruments, and equipment, making it easy to carry and equivalent to a small mobile laboratory. It does not require users to purchase additional accessories and can be used for flexible field testing. It is suitable for agricultural service departments, agricultural supply dealers, cooperatives, fertilizer manufacturers, and large-scale farmers for soil testing and fertilization.

The testing scope covers both domestic and international standards. In addition to the standard reagents, various other reagents can be purchased as optional add-ons. The instrument is easy to operate and provides quick results. It comes with a complete set of accessories and ready-to-use finished reagents, eliminating the need for preparation.

The following parameters can be tested:
1. Soil nutrients: soil ammonium nitrogen, soil available phosphorus, soil readily available potassium, soil nitrate nitrogen, soil hydrolyzable nitrogen, soil total nitrogen, soil total phosphorus, soil total potassium, soil organic matter (Choulin method), soil organic matter (extraction method), soil total organic carbon, soil carbon-to-nitrogen ratio, pH value, salinity, moisture content.
2. Soil trace elements: soil calcium, soil magnesium, soil sulfur, soil silicon, soil boron, soil iron, soil copper, soil manganese, soil zinc, soil chlorine, soil molybdenum.
3. Soil heavy metals: soil lead, soil arsenic, soil cadmium, soil chromium, soil mercury, soil nickel, soil aluminum, soil fluoride, soil titanium, soil selenium.

• This instrument integrates multiple functions into one unit, featuring a high-strength PVC engineering plastic carry case design that is durable and easy to transport. No additional accessories are required, enabling flexible mobile testing.

• It runs on an Android smart operating system, with a main control chip using the ARM Cortex-A7 architecture and an RK3288/4-core processor operating at 1.88 GHz, ensuring faster processing speeds and enhanced stability.

• It features 6 testing channels (solid-state design), enabling rapid testing of 6 samples at once, thereby improving testing efficiency and reducing costs.

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

• Built-in calibration function during testing, intelligent constant current voltage regulation, and automatic light intensity calibration to ensure testing accuracy.

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

• Built-in crop expert fertilization system, capable of calculating recommended fertilization amounts for over 100 types of national agricultural crops, fruit trees, etc., based on target yields, and providing scientific guidance for agricultural production based on fertilization formulas.

• The colorimetric cell section uses standard 1cm colorimetric cells, eliminating mechanical displacement and wear. The optical path testing and positioning are accurate, effectively shielding external light interference, ensuring detection results that exceed national standard requirements.

• Soil testing and fertilization results can be printed, with the printout including: crop type, fertilizer type, target yield, total requirement, and recommended fertilization plan.

• Multiple user accounts with passwords can be set up, featuring an intuitive UI interface. Different users can freely add and edit testing information, which can be saved for long-term use.

• The instrument is equipped with a large-capacity internal memory, supporting access to all historical testing records. Users can log in to the cloud platform via mobile devices to view historical data online and transfer all testing data.

• Equipped with a smart cloud agriculture platform, the instrument can selectively or batch-upload detection data wirelessly after connecting to a wireless network, facilitating long-term data management and visualization analysis for users.

• The instrument also features a USB interface and an Ethernet interface, and data can be copied out using a USB drive at any time.

• GPS functionality: Records latitude and longitude locations during field operations to meet the needs of special users.

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

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

• 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.

• The instrument features a Chinese-English language switching function to meet export requirements. Test items are comprehensive both domestically and internationally. In addition to standard reagents, other types of reagents can be purchased separately.

• High-sensitivity 7-inch true-color touchscreen, featuring more efficient and user-friendly operation, high-definition and high-interactivity display, significantly reducing the cumbersome operations and errors of traditional instruments.

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

• Built-in low voltage warning function to clearly indicate battery level during testing, preventing data drift. Also features power failure protection, automatically saving data in case of power loss to prevent data loss.

• Dual AC/DC power supply option, with a built-in high-capacity rechargeable lithium battery. Can operate continuously for over 10 hours on a full charge and supports external car power supply charging.
