Abstract: Measuring the relative humidity of concrete is a complex process. ASTM F2170 is currently the standard for embedded monitoring relative humidity in newly placed concrete. The process requires a hole to be drilled and cleaned before inserting a relative humidity probe to begin monitoring relative humidity. The measurements are obtained within a specific volumetric space in the concrete. We believe the post-drilling process involves many dependencies, special considerations, and extreme care. With little tolerance for error, this process may lead to misleading results putting the installer at higher risk of installation failure, expensive repairs, and making project decisions based on potentially flawed data. We have invented a cast-in-place device that meets the volumetric space requirements of ASTM F2170 and does not encounter similar issues as noted with the current post-installed sensor.

Abstract: An arrangement (1) for inspecting an object (2) comprising a mobile measuring unit (13) for determining a measured value associated with the object (2). The measuring unit (13) has an interface for interchanging data with further units (12, 14-17). The arrangement also comprises a base unit (3; 12) in which data records (13) can be stored and displayed. A detection mechanism (14) is provided for detecting a measurement position (32), at which the measured value is determined, and/or a measurement time at which the measured value is determined. The measured value determined by the measuring unit (13) can be transmitted, together with measurement position and/or measurement time, as a data record to the base unit (3; 12). The mobile measuring unit (13) determines measured values for an internal structure and/or an internal state of components (8), in particular inaccessible components, of the object (2) in a non-destructive manner.
