Rapid soil testing and fertilizer formula instrument

Features of the rapid soil testing and formula fertilization instrument

1. It can detect various nutrients such as quick-acting nitrogen, quick-acting phosphorus, effective potassium, total nitrogen, total phosphorus, total potassium, organic matter, pH, etc. in the soil.

2. The Android intelligent operating system adopts more efficient and user-friendly operation. The instrument is equipped with wifi network upload, 4G network transmission, and GPRS wireless remote transmission to quickly upload data.

3. The built-in soil testing and formula fertilization system can calculate the recommended fertilizer amount for the target yield of more than 100 kinds of national agriculture, fruit trees, and economic crops, and scientifically guide agricultural production based on the fertilization formula.

4. The built-in plant nutrition diagnosis standard atlas can be used to compare the leaves according to the pictures of the nutritional deficiencies of each crop to diagnose the abundance and deficiency.

5. It is equipped with 6 detection channels as standard, and 6 samples can be quickly detected at one time, which improves the detection efficiency and reduces the detection cost.

6. The colorimetric tank uses a standard 1cm colorimetric dish, without mechanical displacement and wear, and the optical path test positioning is accurate, effectively shielding external light interference, ensuring that the test results are better than the national standard requirements.

7. The instrument has 4G memory, which can store data for a long time, and is equipped with an upload platform. No data cable is required, and data can be directly uploaded wirelessly, which is convenient for data management and long-term data analysis.

8. The instrument has a built-in new generation of high-speed thermal printer, which can automatically print the test report and QR code after the test is completed.

9. High-sensitivity 7-inch capacitive touch screen, high-definition and high-interactive display, greatly reducing the cumbersome operation and errors of traditional instruments.

10. High-strength PVC engineering plastic suitcase design, durable and easy to carry, power supply mode is AC and DC, and can be used for field mobile testing of finished products.

11. The instrument host has built-in operation video, which allows you to learn while experimenting, and it is easy and fast to get started.
