The nuclear density moisture testing machine can determine the moisture, density, compactness, water content, porosity to soil, aggregate, bitumen, concrete quickly and correctly. It adopts the high accuracy imported detector. The instrument is controlled by micro-computer, the operating is very easy. It has the functions of print, inquiry, delete, communication and so on. The detect depth can be 30cm from the surface to the underground. It can be applicable for all kinds of construction material pavement quality detection, like road, airport, park, geotechnical construction, bridge and foundation, dyke, reservoir and so on.
