Measure and manage the unit water content that greatly affects the durability of concrete structures!
The Continuous RI Concrete Moisture Meter COARA (Soil and Rock Engineering) can measure and manage the unit water content, which greatly affects the durability of concrete structures, against the total amount of concrete actually used. This ensures the quality of concrete structures, particularly their durability. The measurement principle involves detecting the transmission of neutron rays related to moisture content and the transmission of gamma rays related to density, calculating moisture content and density based on calibration formulas, and ultimately determining the unit water content of the concrete using other physical property values. Since the density of concrete changes with moisture content and pumping pressure, it is necessary to measure density simultaneously. For more details, please contact us or refer to the catalog.
