The measurement of soil moisture can reflect the crop's need for water, and it has important guiding significance for agricultural production. Therefore, it is very important to study the method of soil moisture determination. Domestic soil moisture measurement techniques include drying method, neutron meter method, gamma ray transmission method, time domain reflectometry (instrument soil moisture real-time monitoring system based on this principle), and soil moisture sensor method (instruments represent regular positioning of soil Moisture velocity measuring instrument), while the domestic soil moisture monitoring technology time domain reflectometry, precision soil moisture detectors and so on. Why is it so important for soil moisture testing both at home and abroad?

Soil moisture affects not only the physical properties of the soil, but also the dissolution, transfer, and microbial activity of nutrients in the soil. It is also the basic condition for the survival of plants. The use of a soil moisture tester to monitor the soil moisture in real time facilitates the understanding of the different requirements of different crops on the soil water content at the same time. The different requirements for the soil moisture content of the same crop at different times and the soil moisture content on the crop yield Impact. Understanding the soil moisture content is particularly important when farming, irrigation, fertilizing and other agricultural measures are adopted. Especially when planning and designing irrigation and drainage, it is necessary to grasp the status and dynamics of soil moisture, and soil Moisture content measurement and understanding not only use the monitoring of farmland, but at the same time when carrying out some construction projects (such as railways, highways, hydropower stations, channels, houses, etc.), soil moisture status is also an indispensable data.
At this time, the detection of soil moisture is indispensable. However, when the traditional drying method is used, although the measurement results are relatively accurate, real-time performance cannot be achieved. When using a soil moisture detector to perform tests, it can not only be implemented, but also ensure the accuracy of the measurement results.
Our isostatic graphite and Molded Graphite were tested at the National Electrical Carbon Products Quality Supervision and Inspection Center. The main physical and chemical performance index as follows: the compressive strength--125 mpa, shore hardness -- 65 degrees, resistivity --12 mu Ω m. At the same time, the 10μm,8μm,6μm,4μm products have already began Large-scale production,.and unanimously acknowledged by customers. The 2μm,1μm graphite products are under trial. Our company high quality of isostatic pressing special graphite yield above 90%, far ahead of industry the yield of 70%, the first in the country.
EDM graphite, also known as graphite block for EDM, is a new type of material, which is now more and more widely used in the precision mold processing industry. At present, in mold processing plants in developed European countries, more than 90% of mold processing electrode materials are graphite. Copper, the once dominant electrode material, has almost lost its advantages compared with graphite electrodes.
