Nuclear density Meter

Nuclear density Meter
This product is used to measure moisture density of the construction material from the surface to 300mm depth. This devise can measure and display wet density and dry density per cent moisture , moisture content and other necessary engineering parameters related to density and moisture contentmaterials.
