the product introduction:
The soil non-nuclear density meter is an alternative nuclear defect meter that measures the physical properties of subgrade and foundation compacted soil. It measures the dielectric properties and density of compacted soil materials by radio high frequency between electrodes. It is a battery-powered portable instrument that can be used anywhere in the world without nuclear safety and other related issues. . EDG measures and displays dry/wet density, water content, and percent compaction. Its superior performance and accurate measurement results are comparable to traditional measurements such as nuclear density measurement, sand blasting, and drying.

♦ The software under Windows has been upgraded to simplify the installation method and data export method. The exported data is an Excel spreadsheet, and the editing and viewing operations are simpler.


四,现场使用方法:
在野外现场,依据模板用锤子将锥形电极或标块以十字式样插入土中。在两个锥形标块的底角之间进行4个点对点的测量并将电特性平均处理。用户可选择用公制SI单位或英制单位显示密度和湿度值。标插入的深度直接影响测量深度。此外,标块的锥度还通过每一次锤击与土壤保持正接触。标块的插入深度决定了测量深度—有不同长度可选。显示屏可显示菜单操作步骤,保存测量结果。
ourth, the use of the site:
In the field, the tapered electrode or the gauge block is inserted into the soil in a cross pattern according to the template. Four point-to-point measurements were taken between the bottom corners of the two tapered blocks and the electrical characteristics were averaged. Users can choose to display density and humidity values in metric SI units or imperial units. The depth of the javelin insertion directly affects the depth of measurement. In addition, the taper of the gauge block is also in positive contact with the soil by each hammering. The insertion depth of the standard block determines the depth of measurement - there are different lengths available. The display shows the menu operation steps and saves the measurement results.

五,测试原理: 
无核密湿度仪(EDG)通过电极之间的无线电高频率来测量压实土壤材料的介电性和密度,并将测量得到的介电性与“土壤模块”做比较。“土壤模块”是土壤类型的特定标准,它有一组预先测量得到的特定介电性,这组介电性代表了一系列的密度值和湿度值。野外测量结束后,利用数学运算法则会计算出干/湿密度、含水量,以及压实百分数。随附的温度探测器还可以增加测量的精确性。
Five, the test principle:
The Nuclear Free Humidity Meter (EDG) measures the dielectric properties and density of compacted soil materials by radio high frequencies between the electrodes and compares the measured dielectric properties to the “soil module”. The “soil module” is a specific standard for soil type. It has a set of pre-measured specific dielectrics that represent a range of density and humidity values. After the field measurement is completed, the dry/wet density, water content, and percentage of compaction are calculated using mathematical algorithms. The included temperature probe also increases the accuracy of the measurement.
