Portable Plant Nutrition Tester

Features of portable plant nutrition determination instrument

1. It can quickly detect the content of available nitrogen, available phosphorus, effective potassium, total nitrogen, total phosphorus, total potassium, organic matter, nitrite, various trace elements such as calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, and various heavy metals such as lead, chromium, cadmium, mercury, and arsenic in living crops and dry plants.

2. Android smart operating system, using more efficient and humanized operation, the instrument is equipped with wifi networking function and 4G networking function as standard, and realizes wireless 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 economic crops, and scientifically guide agricultural production according to the fertilization formula.

4. The dual-row multi-channel design 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.

5. Built-in plant nutrition diagnosis standard atlas, according to the pictures of nutritional deficiencies of various crops, leaf comparison is carried out to diagnose abundance and deficiency.

6. Adopting high-precision filter technology independent analysis method, the colorimetric tank part adopts standard 1cm colorimetric dish, without mechanical displacement and wear, accurate optical path test positioning, and ensure that the test results are better than national standards.

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 realize constant current voltage regulation to ensure wavelength stability. Silicon semiconductor is used as a signal receiving system with a life 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 pharmaceuticals.

Functions and test items of portable plant nutrition tester

Plant nutrients:

● Nitrogen, phosphorus, potassium and other items in plants.

● Medium and trace elements in plants: calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, etc.

● The content of various heavy metals such as lead, chromium, cadmium, mercury, arsenic, etc. in plants.

It can also be expanded to detect: nitrogen, phosphorus, potassium, organic matter, trace elements, heavy metals, etc. in soil, fertilizer, food, and water quality
