High-intelligent fertilizer detector

Instrument features

1. The highly intelligent fertilizer detector can detect various trace elements such as total nitrogen, total phosphorus, total potassium, organic matter, calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, and various heavy metals such as lead, chromium, cadmium, mercury, and arsenic in chemical fertilizers and organic fertilizers (including foliar fertilizers, water-soluble fertilizers, spray fertilizers, etc.).

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 highly intelligent fertilizer detector has a 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 economic crops, and scientifically guide agricultural production based on the fertilization formula.

4. The built-in plant nutrition diagnosis standard atlas, according to the pictures of the nutritional deficiencies of each crop, the leaf surface is compared to diagnose the abundance and deficiency.

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

6. The colorimetric tank uses a standard 1cm colorimetric dish, which has no mechanical displacement and wear. 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. Highly sensitive 7-inch capacitive touch screen, high-definition and high-interactive display, greatly reducing 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 stabilization 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, power supply mode is AC and DC, and can be used for field flow testing of finished pharmaceuticals.

12. The instrument host has built-in operation video, learning while experimenting, and getting started is simple and fast.
