location：In modern agricultural production, understanding the nitrogen (N), phosphorus (P), and potassium (K) content in soil is the foundation of scientific fertilization. The soil analyzer can complete the determination of three key nutrients in just 20 minutes. How does this efficient device with 12 detection channels achieve fast and accurate measurements? This article will provide a detailed analysis of the working principle and technical secrets of soil analyzers for measuring nitrogen, phosphorus, and potassium content.
The soil analyzer adopts a design of 12 rotating detection channels, and achieves synchronous extraction and color comparison of 12 samples through a solid-state optical path system. Its core advantages lie in:
Parallel processing capability: A single batch can complete the detection of nitrogen (N), phosphorus (P), and potassium (K) in 12 soil samples, which is 12 times more efficient than traditional spectrophotometry
Patent filtering technology: equipped with high-precision filters, with a wavelength accuracy of ± 0.5nm, effectively filtering out stray light interference
Intelligent constant current voltage stabilization: Equipped with an automatic light intensity calibration module, the stability calibration of the light source is completed before each batch of testing to ensure that the absorbance value CV is ≤ 1.5%
After the completion of soil analysis and testing, the data can be uploaded in real-time to the smart cloud agriculture platform through WiFi, 4G, or GPRS. Users can view historical data and trends at any time through the mobile app.
It is worth mentioning that soil analysis also integrates FDR sensors and environmental multi-element sensors. FDR sensors can synchronously measure soil moisture, temperature, and conductivity, while environmental sensors monitor six parameters including air temperature, humidity, and light. These data, combined with nitrogen, phosphorus, and potassium content, provide comprehensive decision support for precision agriculture. The instrument's built-in large capacity memory and multiple data interfaces ensure secure storage and convenient transmission of detection data, achieving seamless connection from the field to the cloud.
