Plant nutrient rapid tester

Plant nutrient rapid tester

Android intelligent operating system, can detect the nitrogen, phosphorus, potassium, organic matter, trace elements and heavy metal content of plants, and quickly detect 12 samples.

Features:

1. It can quickly detect the quick-acting nitrogen, quick-acting phosphorus, effective potassium, total nitrogen, total phosphorus, total potassium, organic matter, nitrite, calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, molybdenum and other trace elements and various heavy metals such as lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium in living crops and dry plants.

2. Android intelligent 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, can calculate the recommended fertilization amount for the target yield of more than 100 kinds of national agriculture, fruit trees and cash crops, and scientifically guide agricultural production according to 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. 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.

6. The high-precision filter technology independent patent analysis method (patent number: ZL 2018 2 1777724.7) is adopted. The colorimetric tank part adopts the standard 1cm colorimetric dish, without mechanical displacement and wear, and the optical path test positioning is accurate, 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 the 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 reduces 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 pharmaceuticals.

Multiple functions and complete test items:

Plant nutrients: ● Nitrogen, phosphorus, potassium in plants; nitrite, etc.

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

● The content of various heavy metals such as lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium, 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

Technical indicators:

Test speed:

Test one plant sample (N, P, K) ≤40 minutes, and test three plant samples (N, P, K) at the same time ≤1 hour.

Test error:

Test error ≤5%.

Features:

Full function: comprehensive test items at home and abroad (all kinds of agents can be purchased).

Complete supporting facilities: The instrument integrates medicine, equipment and instrument into one, which is easy to carry and equivalent to a small laboratory. It is suitable for crop nutrition diagnosis and plant physiology research in colleges and universities and scientific research institutes. Agricultural service departments or agricultural material dealers, fertilizer manufacturers, etc. for soil testing and fertilization.

Easy to operate and fast, the finished medicine is ready to use after opening the bottle, and no configuration is required.

Reliable performance: The working stability is 6 times better than the national standard JJG179-90 index, and the repeatability reaches the index level of grating spectrophotometer.
