1. It can detect the quick-acting nitrogen, quick-acting phosphorus, effective potassium, total nitrogen, total phosphorus, total potassium, organic matter, pH, calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon and other trace elements and various heavy metals such as lead, chromium, cadmium, mercury and arsenic in soil and fertilizers, organic fertilizers (including foliar fertilizers, water-soluble fertilizers, spray fertilizers, etc.), plants.

2. Android smart operating system, using more efficient and humanized operation, the instrument is equipped with wifi network upload, 4G network transmission, GPRS wireless remote transmission, and fast data upload.

3. Built-in crop expert fertilization system, which can calculate the recommended fertilizer amount for the target yield of more than 100 kinds of national agriculture, fruit trees, and cash crops, and scientifically guide agricultural production based on fertilization formulas.

4. Built-in plant nutrition diagnosis standard atlas, according to the pictures of nutrient deficiencies of various crops, leaf comparison, diagnosis of abundance and deficiency.

5. The dual-row multi-channel design can quickly detect 12 samples at a time, and all test items can be tested in all channels at the same time, which greatly improves the test efficiency and reduces the test cost.

6. The colorimetric tank uses a standard 1cm colorimetric dish, without mechanical displacement and wear, accurate optical path test positioning, and effectively shields 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. Highly sensitive 7-inch capacitive touch screen, high-definition and high-interactive display, greatly reduce the cumbersome operation and errors of traditional instruments.

10. Each channel is equipped with a four-wavelength cold light source, and all light sources achieve constant current voltage regulation to ensure wavelength stability. Silicon semiconductors are used as signal receiving systems with a lifespan of up to 100,000 hours. Good reproducibility and high accuracy.

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

12. The instrument host has built-in operation video, learning while experimenting, easy and fast to get started.
