Instrument Introduction:
Soil nutrient rapid testing instrumentCan detect nitrogen, phosphorus, potassium, pH value, and salt (conductivity) value. The application of this instrument has alleviated the demand for soil testing and formula fertilization among farmers in various regions, and also provided a reliable basis for fertilizer production enterprises to achieve specialization, systematization, informatization, and dataization. It is an instrument for soil testing and formula fertilization in the agricultural sector. Widely used in various levels of agricultural testing centers, agricultural research institutions, fertilizer production, agricultural material management, agricultural technology services, planting bases and other fields.

Instrument features:
1. The soil nutrient rapid tester can detect five types of test results, including nitrogen, phosphorus, potassium, pH value, and salt (conductivity) value. The results can be stored and printed separately on the host, and the host stores the data. Chinese LCD backlight.
2. Has time display storage. The instrument has a memory of 73 types of nutrients required for crops, and can output fertilization guidance formulas. It has charging and printing functions, and can be used for both AC and DC.
3. The host can store no less than 1000 sets of test data, which can be accessed and viewed at any time.
4. The storage and printing content includes relevant information such as testing date, testing time, testing items, sample content, crop variety, fertilizer variety, and fertilizer quantity.
5. You can select fertilizer and crop varieties on the host, input the target yield, and automatically calculate the recommended fertilizer amount.
6. The fertilizer utilization rate can be adjusted arbitrarily on the host. The fertilization adjustment coefficient and crop fertilization parameters can be adjusted arbitrarily according to different regions.
7. The bilingual switching function between Chinese and English, with a large LCD screen displaying Chinese or English and guiding each step of the operation process.
8. During the testing process, there is a review function, which makes the product more convenient and reasonable (with backlight function, able to adapt to night use).
9. Crop varieties, crop yields, and fertilizer varieties can be set according to local conditions, and the amount of fertilizer applied can be automatically calculated.
10. The test sample results are automatically transferred to the computer for analysis, summary, and storage, with 73 types of nutrients required for crop growth and development stored in memory; It can be stored by a computer for data storage, remote transmission, and printing. It can also be used to test soil formulas on the host computer and print them out through a micro printer, with both AC and DC capabilities.
11. You can choose to add a soil moisture sensor (optional).

Instrument management cloud platform functionality
1. The instrument comes with an instrument cloud management platform that includes a C/S architecture, which can summarize and analyze data from all portable and online devices without losing data backups. The viewing and operation methods include web and mobile devices (Android system).
2. Display the detection time, detection items, absorbance, and concentration of each channel; And corresponding information such as crop types, fertilization types, and fertilization plans.
3. The data can be synchronized to the management cloud platform. Data within the platform can be downloaded, analyzed, and printed.
4. The platform supports the addition of multiple devices, supports cloud storage of device data, and provides sufficient capacity for long-term storage.
5. The platform provides report formats such as curves and tables for device data, and the data can be exported and imported.
6. The software can be upgraded online.

Expand reading:
nutrientsThe essential nutrients provided by soil for plant growth. Mineral nutrients in soil that can be directly or transformed and absorbed by plant roots. Including 13 elements such as nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), iron (Fe), boron (B), molybdenum (Mo), zinc (Zn), manganese (Mn), copper (Cu), and chlorine (Cl). Nutrients are classified into macroelements, moderate elements, and trace elements. In natural soil, the main sources are soil minerals and organic matter, followed by atmospheric precipitation, slope seepage, and groundwater. In cultivated soil, it also comes from fertilization and irrigation.
