Soil Test ST-4
A soil test is a fundamental agricultural and environmental analysis used to assess the chemical and physical properties of soil. By analyzing a representative sample in a laboratory, it provides crucial data on key fertility indicators such as soil pH, levels of essential nutrients (like nitrogen, phosphorus, and potassium), and organic matter content. The primary goal is to generate a scientifically-based fertilizer and amendment recommendation.
Introduction
The handheld measurement platform adopts the latest digital integrated circuit technology and international detection technology to design a new intelligent handheld detector.
The detector adopts a large-scale full-color liquid crystal display, which can display the reading in real time. At the same time,it uses the detection circuit designed by the digital chip of international large factories, which can achieve very high sensitivity and excellent repeatability. The shell is made of high-strength composite plastic for industrial use, which has a good sense of strength.
