location：The highly intelligent soil nutrient rapid tester integrates complex laboratory analysis processes into portable devices, integrating medicine, equipment, and instruments into one, equivalent to a portable mobile intelligent laboratory, achieving rapid, accurate, and on-site determination of soil, fertilizer, and plant nutrients, providing strong technical support for soil testing and formula fertilization.
Working principle: Integration of photoelectric colorimetric method and intelligent analysis
The core detection principle of the highly intelligent soil nutrient rapid analyzer is the photoelectric colorimetric method.
1. Optical detection system
The instrument adopts a four wavelength professional testing cold light source (red, blue, green, orange), and is designed with a precision rotating colorimetric cell (patent number: ZL 2018 2 1777724.7) to ensure that each sample is tested under consistent optical conditions. The unique high-precision filter technology (patent number: ZL 2020 2 1763837.9) can * * separate the characteristic absorption wavelength of the target element, effectively eliminating interference factors.
2. Chemical color development principle
Different soil nutrients react with specific reagents to produce colored compounds with characteristic absorption at specific wavelengths. Based on Lambert Beer's law, the depth of solution color is quantitatively related to nutrient concentration, and nutrient content can be calculated by measuring absorbance values.
3. Intelligent data processing
The instrument is equipped with an ARM Cortex-A7 quad core processor (with a main frequency of 1.88GHz), which automatically converts absorbance values into nutrient content through preset calibration curves and algorithm models. The system has intelligent constant current voltage stabilization and automatic light intensity calibration functions to ensure the stability of the detection process and the accuracy of the results.
Technical Advantage: Why is it an ideal choice for on-site testing?
1. Testing performance and efficiency
This highly intelligent soil nutrient rapid tester performs excellently in terms of detection accuracy. The detection error of soil nitrogen, phosphorus, and potassium is ≤ 1%, the error of organic matter is ≤ 2%, and the relative error of trace elements is ≤ 5%. The design of 8 rotating detection channels supports simultaneous detection of batch samples, greatly improving work efficiency. Under normal and proficient operation, it only takes 20 minutes to test one soil sample (N, P, K), and no more than 1 hour to test 8 soil samples simultaneously.
2. Coverage of testing items
The instrument supports over 100 testing items in seven categories including soil, fertilizer, plants, and water quality, covering:
Soil nutrients: basic nutrients such as ammonium nitrogen, available phosphorus, and available potassium
Medium and trace elements: calcium, magnesium, sulfur, silicon, boron, iron, copper, manganese, zinc, etc
Heavy metal indicators: lead, arsenic, cadmium, chromium, mercury, etc
Fertilizer nutrients: total nitrogen, total phosphorus, total potassium, and various trace elements
3. Intelligent operation experience
Equipped with Android intelligent operating system and 7-inch true color touch screen, with built-in sample pre-processing operation video guidance, greatly reducing the operating threshold. The smart cloud agriculture platform supports wireless data transmission and long-term management, making it convenient for users to analyze historical data and make trend judgments.
4. Portability and reliability
High strength PVC engineering plastic carrying case design, with AC/DC dual-use power supply, built-in large capacity rechargeable lithium battery, can work continuously for more than 10 hours when fully charged, perfectly adapting to the needs of field operations. The job stability is six times better than the national standard JJG179-90, ensuring reliable operation in various environments.
Application Fields and Solutions
